- Capstone Design Team Wins Gold Medal At 2017 iENA
- SKKU's Capstone Design Team (SKKU LINC+ Team) won a gold medal in the field of Inventions/New Products at the 2017 International Trade Fair for Ideas - Inventions - New Products (iENA 2017) held in Nuremberg, Germany from November 2nd to 5th. Germany's iENA, which celebrated its 69th anniversary since its first exhibition in 1948, is one of the world's 3 largest invention exhibitions, along with Pittsburgh (USA) and Geneva (Switzerland). This year, 745 teams from 29 countries participated in the event. The SKKU Capstone Design Team that participated in iENA took the Global Capstone Design course (advising professors: Sang Do NOH, Kwan Soo HAN) during the 1st semester of the academic year. Through this course, they developed a Safety Intelligence Module that can be attached to a personal mobility device such as a bicycle or a Segway. Afterward, in the 2nd semester Deep Convergence Capstone Design course (advising professors: Jun-Dong CHO, Ji Sook CHUNG), through a connected course they have developed prototypes that are close to actual commercialization. Prof. Jun-Dong CHO, who supervised the Capstone Design Team, said, "As the domestic and overseas personal mobility market grows rapidly and the number of related safety accidents soars, the need for active safety devices to prevent accidents will become increasingly important. We will go through practicality and safety verification steps through test drives on the roads, and we will connect with start-ups to further raise the degree of completion through continuous mentoring." Meanwhile, this year's LINC+ Project has been strengthening its support for outstanding capstone design projects through patent applications, participating in domestic and overseas competitions, and industrializing start-up connections. This has resulted in excellent achievements at competitions such as the 'PACE Annual Forum' held in Toluca, Mexico, and the 'Seoul Idea Competition (I Digital U).'

- Prof. Soong Ho UM Discriminates a Tumor Heterogeneity Using a Fluorescence-encoded DNA Nanostructure
- A tumor is a devastating disease, and it is important to apply appropriate therapeutic and diagnostic tools to accurately detect the cancer stage and type. Early detection of cancer is associated with a higher percentage of recovery after treatment, and it is more important to identify the molecular signature of cancer as early as possible. Micro-RNA, which is abbreviated miR or miRNA, has recently been known as a potential tumor-associated signature that can indicate early cancer development. In addition, because miRNAs regulate transcription of mRNA in the upper level of the cascade, a miRNA network significantly influences cellular metabolism, development, differentiation, establishment, and even stress response. miRNA profiles provide essential clues about metabolic heterology in tumorigenesis. Types and mechanisms of cancer-specific miRNAs can be identified for clinical index. Quantification of multiple miRNAs in a living cell leads to better understanding of cancer. Significant correlation of specific miRNA variances that exist during progression from primary tumor to metastasis can be used to predict the effective diagnosis of whole-stage cancer. Moreover, in addition to a change of tumor concept, in which there is a successive process of clonal evolution at the tumor site, cell-to-cell variation and interfacial communication should be detected for personalized medicine. Several nanotechnology-based systems were developed for miRNA detection at the cellular level. However, quantitative analysis of multiplex miRNAs in a living cell is difficult due to the cellular transport kinetics of each cell type. To date, Prof. Soong Ho UM and Dr. Seung Won SHIN present a novel miRNA detection platform using fluorescence-encoded nanostructured DNA probing for quantitative analysis of multiplexed miRNAs in living cells. His research group has been working for over a decade to design novel molecular diagnostic tool kits based on DNA nanotechnology for biomedical purposes. Nanotechnology-engineered platforms as synthesized can provide highly programmable and predictable labeling of various miRNAs specific to the type of cancer in a technically simple manner at the molecular scale. In this study, Prof. UM and his colleagues demonstrate that it is eventually possible to encode fluorescence colors of cancer-specific miRNA signatures in cells using new DNA nanotechnology and to track the presence of fluorescent cells in in situ. Prof. UM speculates that this novel nanostructured DNA-based diagnosis can provide not only important information for tumorigenesis, but can also be applied in personalized medicine as an easy-to-use tool kit. This demonstration of efficient cancer cell labeling and its in situ cancer-staged tracking and tumor heterogeneity, which may be not easy to be realized without this new scientific tool kit, will be of great interest to anyone who is seeking for a new scientific report for progressive technology developments at a cutting-edge cancer diagnosis. This work was supported by a grant from both the Korea Health Technology R&D Project through the Korea Health Industry Development Institute (KHIDI) funded by the Ministry of Health & Welfare and the Basic Science Research Programs through the National Research Foundation of Korea (NRF) funded by the Ministry of Science, ICT, and Future Planning, Republic of Korea.

- Prof. Gi Ra YI Develops New Method for Mass Production of Patchy Particles
- □ Associate Professor Gi-Ra YI in School of Chemical Engineering, Sungkyunkwan University and Assistant Professor Stefano SACANNA at chemistry department of New York University developed together new method for mass production of patchy particles which can be assembled as do molecules. □ Researchers began with a set of four large solid polystyrene spheres arranged in a tetrahedral manner around a smaller, softer silicone oil droplet. These two components are oppositely charged and thus spontaneously assemble into clusters. They then add a plasticiser (terahydrofuran), which allows the polystyrene spheres to flow and reconfigure into a single, bigger sphere thanks to surface tension. This process can be likened to the way balls of playdough can be squashed together. As the outer spheres fuse together to form a single sphere, the inner silicone oil droplet in fact deforms to fill the spaces inside the sphere. It is eventually pushed out to form a tetrahedral pattern of patches on the sphere’s surface. These patchy spherical-shaped particles are produced in over 90% yield. □ Adding patches to self-assembling systems in this way could allow us to produce colloidal nanostructures. Until now, however, it was not easy to yield enough particles to make a material big enough to hold in their hands. □ On the other hand, at low pH, oil droplets surrounded with four spheres can be stayed in the center during deformation by adding plasicitizer, in which oil droplets are first faceted into tetrahedra and then become spheres. Researchers can polymerized in the middle of deformation which produced uniform tetraheron particles. □ The research is detailed in Nature doi:10.1038/nature23901. □ “Mass production of patchy particles has been one of most important problem in fabricating nanostructured materials by self-assembly” says Prof. Gi-Ra Yi. This will be used now for builidng up new colloidal structures which may be used for even 3D printers with complex internal nanostructures.

- Development of X-ray Material with Almost No Radiation Using Microcrystalline Halide Perovskites
- A collaborative research project with Samsung Electronics A semiconductor material that can reduce the amount of radiation exposure while taking medical X-ray images to less than 1/10 has been developed. On the 11th, it was announced that an ‘X-ray detector’ that can increase sensitivity by over 20 times more than conventional flat X-rays by using perovskites semiconductor material was developed. An X-ray detector is a kind of image sensor that absorbs X-rays. The new material developed by the research team has high sensitivity, so it is possible to obtain a clear medical image while reducing the radiation dose. The cost of production is also low. Unlike conventional detectors, which are made by vacuum processing used in semiconductor manufacturing, the new detector can be made through a liquid process, so a large screen can be made. If this technology is commercialized, it will be possible to make X-ray devices that can take an image of the whole body at once. Perovskite has excellent characteristics of converting light into an electric current, so it is a material that is very popular in the fields of solar cells and X-rays. X-ray devices are widely used for medical purposes because they can convert X-rays transmitted through the human body into pictures and images, but they are expensive and result in large doses of radiation. For this reason, research and development projects to reduce X-ray exposure are being widely carried out in the United States, European Union, etc. The research team expects that X-ray devices that can dramatically reduce X-ray exposure will be developed in a few years. If the remaining technical problems are improved, X-ray medical imaging technology that reduces the radiation dose to less than 1/10 is expected to be available in the practical field of medicine. The results of this research have been published in the online edition of the worldwide scientific journal Nature, titled "Printable organometallic perovskite enables large-area, low-dose X-ray imaging."

- Prof. Nam Gyu PARK was selected for “2017 Potential recipients of the Nobel Prize"
- Clarivate Analytics announced its 2017 Citation Laureates The only known Korean awardee, Prof. PARK is receiving recognition for his study on highly efficient perovskite materials Clarivate Analytics recently announced its 2017 Citation Laureates. Each year since 2002, analysts at Clarivate Analytics have mined millions of citations in the Web of Science to identify top-tier researchers in physiology or medicine, physics and chemistry – fields recognized by the Nobel Prizes in science. It also names Citation Laureates in economics, since the Swedish National Bank established an award in this domain, in memory of Alfred Nobel, in 1968. Citation Laureates are scientists and economists whose publications have been cited so often by their colleagues – and thus who have been so influential – that they are forecast as potential recipients of the Nobel Prize in this year or in the future. This year, Clarivate selected 22 researchers for their ‘2017 Citation Laureates’ and Prof. Nam Gyu PARK at SKKU School of Chemical Engineering was the only known Korean awardee. He is receiving recognition for his study on highly efficient perovskite materials. Below is Prof. PARK's interview. “It is my honor to be selected as a potential Nobel Prize awardee” Although I have not yet been selected as a Nobel Prize winner, it is a great honor to have my name on the list of researchers expected to receive a Nobel Prize. There is no special secret to obtaining this kind of result. To be honest, I think that research is interesting and enjoyable. It’s always a pleasure to discover new things and to challenge oneself to be the first and the best. Above all, I am fortunate to have been able to conduct research in the field of solar cells for more than 20 years. I have been able to meet outstanding researchers from all over the world and had many opportunities to collaborate with them because I have been conducting research in only one field. Today’s research results would not have been possible without the help or cooperation of the students and researchers around the world who have collaborated with me. Korean Nobel Prize Winner It seems that the whole nation thinks it’s a pity that a Nobel Prize has not come out of Korea yet, and that we have no Nobel Prize winners compared to our neighboring country Japan. However, compared to other places like Japan and Europe, Korea does not have a long history in the field of science and technology. As many Nobel Prize winners and countries have done, at the foundation of every field we will need a culture that waits for long research periods and does not demand results in a short period of time. Most researchers in Korea are pouring all of their passion into their research and hoping that the results of their research will elevate the nation’s status and contribute to the happiness of humankind. Suggested direction for research development For long-term academic advancement, it will be necessary to create an environment where researchers can be at ease and enjoy their research. There is a need to develop measures such as strengthening rewards for researchers to create more valuable research results. We also need large-scale group research such as the Global Frontier project, and we need to discover excellent researchers by further expanding creative tasks that help individual researchers conduct creative research. Above all, continuous development of science and technology is possible in a culture where scientists are respected and researchers take pride in their studies. The need for global researchers Science and technology are progressing exponentially in the 21st century. We are living in an era where new technologies are constantly emerging and existing technologies are rapidly disappearing. We need researchers to be able to plan out the present and accurately perceive the future society. No new technology is created overnight. Multiple improvements can create an entirely new kind of technology. When integrated knowledge in one field is combined with surrounding technology, completely new technologies can be created. In order for all of this to be possible, we should break down the walls between individual researchers and countries and conduct joint research. I think that the life of the technology we have developed today is not so long, and I am confident that if we continually challenge ourselves, we can create a lot of outstanding new technologies.

- Profs. Gi-Ra YI & Jaeyun KIM's Study on Vanishing Colloidal Mesoporous Nanoparticles to Heal Wounds
- The research team under Profs. Gi-Ra YI and Jaeyun KIM at Sungkyunkwan University's Department of Chemical Engineering have developed a colloidal mesporous nanoparticle solution that has the potential to rapidly and and effectively close wounds in the skin when it spreads, then degrades away after the wound heals. Figure 1. Schematic illustration of wound healing process on mouse skin by applying mesoporous nanoparticles The fundamental research behind the rapid wound closure is the high surface area of the colloidal mesoporous silica nanoparticles in which extracellular matrixes within biological tissues are strongly absorbed on the surface of the nanoparticles; therefore, the wound is rapidly closed. By introducing the mesopores and controlling the average diameters on the surface, the research team has shown increases of up to 10 times more adhesion energy compared to nonporous silica nanoparticles, even at 10 times lower concentration. Figure 2. Graphical illustration of extracellular matrixes interacting on the surface of mesoporous nanoparticles The team has also compared the use of colloidal mesoporous silica nanoparticles with conventional suturing and chemically treating agents in wound closure. The result confirmed that the colloidal mesoporous silica nanoparticles are much more convenient to use, the adhesion was stronger, and most importantly, there were no signs of inflammation or scars. Figure 3. In vivo comparison of wound healing on mice by methods and time Once the wound is closed and healed, the colloidal mesoporous silica nanoparticles degrade easily in biological media. The fact that colloidal silica nanoparticles degrade is advantageous, confirming the possibility of being used as biocompatible adhesive material. The research was supported by the Engineering Research Center and the Bank of Porous Nanoparticles from the National Research Foundation (NRF) of Korea, and was published in the journal ACS Applied Materials and Interfaces (Impact Factor 7.504) on August 24th, 2017. Title: Colloidal Mesoporous Silica Nanoparticles as Strong Adhesives for Hydrogels and Biological Tissues Authors: Joo-Hyung KIM (Research Assistant), Hodae KIM (M.S.), Youngjin CHOI (Ph.D), Doo Sung LEE (Professor), Jaeyun KIM (Associate Professor), and Gi-Ra YI (Associate Professor) The research team is currently continuing this study to combine wound healing agents for colloidal mesoporous silica nanoparticles capable of dual rapid closure/healing treatments.
