We will discuss the stable and selective photogeneration of aminium and aminyl radicals from the same amine precursor via tunable charge carrier imbalance condition enabled by the photoinduced anion exchange that opens unconventional but highly effective pathway of removing electrons irreversibly from the NCs. The coupling between the radicals photogenerated by CsPbX3 NCs, for which II-VI semiconductor NCs are catalytically inactive, will also be discussed.

In this talk, first, I will go over some of my past research on “Trehalose Glycopolymers and Hydrogels for Enhancing Protein Stability”. Then I will focus on my career journey by sharing my experience throughout Yonsei University, University of California, Los Angeles (graduate school), California Institute of Technology (post-doctoral), and being part of the US Biotech industry, Moderna. The talk will be informal, engaging, and interactive by encouraging active participation and questions from the audience.

지난 2022년 5월 20일 금요일, 연세대학교 본관에서 연세대학교와 기초과학연구원(IBS)의 기관장 간담회가 개최되었다. 이번 간담회를 통해, 세계적 수준 기초과학 창출 및 진흥을 위한 연세대와 IBS의 협력관계의 고도화에 대해 논의하는 시간을 가졌다.

천진우 교수는 우수한 연구 업적을 달성한 공로를 인정받아, 2021년 연세대학교 언더우드 특훈교수로 임명되었다.

On the 13th of May 2022, the Teacher's Day Ceremony and Happy Hour of IBS CNM was held at the Auditorium and IBS Lounge at IBS Hall.

The presentation will explain timeresolved and time-gated FRET and the specific benefits for spectral and temporal luminescence multiplexing with different materials and instruments. Then, recent applications concerning multiplexed FRET biosensing and bioimaging in solution, in-vitro, in-situ, and in-vivo with a special focus on optical barcoding and molecular logic gates will be discussed.

Quantum dot is a semiconductor nanoparticle having a size of 1 to 10 nm, and it is easy to control color by size or composition, and has the advantage of high luminous efficiency and narrow peak width. Color is very important factor to realize images in the display, so superior quality values of displays are not achievable without a higher color gamut. Quantum dot is very promising emission material to realize high color gamut. In this seminar, I would like to talk about the application of QD to display and how Samsung has developed advanced display with QD.

On Tuesday, May 10th, 2022, the 6th Special Seminar of IBS CNM & NanoBME will be held at the Auditorium at IBS Hall at 4:30 p.m.

My academic journey with Bio AFM started with dendron-coated AFM probes that enable truly one-to-one interaction leading to enhanced accuracy and reproducibility. Such approach enables direct quantification of DNA, mRNA, microRNA, and proteins of low abundance without amplification or labeling. Also, we are pleased to demonstrate that the force mapping visualizes various biomolecules on cell surface at the nanometric resolution. The highest sensitivity and spatial resolution pave a new avenue for the bioanalysis. In particular, application for liquid biopsy is quite attractive because direct and sensitive nature allows us to diagnose cancer at early stages with the minimal false signals.
