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.

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.

On the 10th of January 2022, the Kick-off Meeting of IBS CNM was held at the Auditorium at IBS Hall.

The presentation will highlight recently demonstration of the anticipated benefits of the upconverted hot electrons in several photocatalytic reduction and redox-neutral reactions. Development of new material platform for more efficient hot electron upconversion and the prospects of expanding the application of the energetic hot electrons in beyond photocatalysis will be discussed.

In this talk, we discuss the recent progress in the design and fabrication, modeling and simulation, and actuation and control of magnetic soft materials and robots. We discuss the continuum mechanical framework for hard-magnetic soft materials and design guidelines for optimal performance of magnetic soft actuators. We then discuss the potential of magnetic soft robots for biomedical applications, focusing on our example of magnetic soft continuum robots towards telerobotic neurointervention for treating stroke and aneurysms.
