[Event] [Event] 2022 ASI/IBS CNM Kick-off Meeting (Jan 11, 2022) Hot

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

[Seminar] [Special Seminar] Prof.Dong Hee Son (Texas A&M/Yonsei ASI), Jan/11/2022 "Hot electrons generated via upconversion for enhancing photoinduced chemical processes" (Dec 31, 2021)

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.

[Seminar] [Special Seminar] Yoonho Kim, Ph.D (MIT), Dec/21/2021 "Magnetic Soft Materials and Robots for Biomedical Applications" (Dec 17, 2021)

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.

[Seminar] [Special Seminar] Prof.Donghoon Son (Pusan National University), Dec/08/2021 "Minimally Invasive Mobile Medical Robots" (Nov 26, 2021)

In this seminar, magnetically actuated small scale magnetic robots will be presented. The magnetic actuation has advantages over conventional robotic actuation methods based on linkages, because of directly and remotely addressable magnetic forces and torques. In medical robotics, such favorable properties can minimize the invasiveness of diagnostic and surgical procedures. In this talk, this will be shown in two applications: magnetically actuated soft capsule endoscopes and magnetically actuated milli-scale robots for neural navigation. By applying the magnetic principles to the robotics methods, such as design, localization, calibration and control methods, the magnetically actuated robots are designed, fabricated, and controlled at our command. This talk will focus on the use of magnetics into robotic systems, dealing with interesting properties of magnetic actuation, and showing how this technology can be seamlessly combined with the current medical technologies.

[Forum] IBS Conference on Nanomachines for Biotechnology and Medicine (Nov 15, 2021)

IBS Conference on Nanomachines for Biotechnology and Medicine was held at The Plaza and Yonsei University between two days 8-9th November 2021.

[Seminar] [Special Seminar] Prof.Eui-Cheol Shin (KAIST&IBS), Nov/23/2021 "Phenotypes and functions of SARS-CoV-2-specific T cells" (Nov 15, 2021)

In this lecture, I will review immune responses against SARS-CoV-2 and VOCs. In particular, I will focus on SARS-CoV-2-specific CD4+ and CD8+ T cell responses that have been detected and characterized among not only COVID-19 patients and convalescents but also unexposed individuals. I will lecture on phenotypes and functions of SARS-CoV-2-specific T cells in COVID-19 patients and the relationships between SARS-CoV-2-specific T cell responses and the severity of COVID-19. In addition, I will lecture on phenotypes and functions of SARS-CoV-2-specific memory T cells after recovery from COVID-19. I will also discuss the presence of SARS-CoV-2-reactive T cells in unexposed individuals and SARS-CoV-2-specific T cell responses elicited by COVID-19 vaccination.

[Seminar] [Special Seminar] Prof.Kwanghun Chung (MIT&Yonsei), Jul/06/2021 "Technologies for illuminating health and diseases: from ideas to impact" (Jun 30, 2021)

Understanding disease mechanisms and developing new therapeutic strategies requires holistic measurement of diverse anatomical and molecular traits that span multiple levels, from cells to an entire system. In this talk, I will discuss new technologies for studying organ-scale biological systems and how we can accelerate the technology adoption to maximize the impact.

[Seminar] [Special Seminar] Prof. Jayoung Kim (Yonsei), 23/Mar/2021 "Wearable biosensors for healthcare applications (Mar 17, 2021)

Wearable biosensors represent a promising opportunity to continuously and non-invasively track human physiology through dynamic measurements of chemical markers in bio-fluids such as sweat, tears, saliva and interstitial fluid. Such biosensing platforms can thus offer real-time biochemical information toward a more comprehensive view of a wearer’s health, performance or stress at the molecular level. The growing recent interest in wearable and mobile technologies has led to increased research efforts toward development of non-invasive biomarker monitoring platforms. Continuous biomonitoring addresses the limitations of finger-stick blood testing and provides the opportunity for optimal therapeutic interventions. The research during PhD is focused on developing wearable sensors and biosensors along with non-invasive biosensing opportunities and the potential impact of such wearable devices on our daily life....

[Seminar] [Special Seminar] Prof. Sung-Yon Kim (SNU), 4/Feb/2021 "How do we stop eating when we are full?" (Feb 4, 2021)

Mechanosensory feedback from the digestive tract to the brain is critical for limiting excessive food and water intake, but the underlying gut–brain communication pathways and mechanisms remain poorly understood. Here we show that, in mice, neurons in the parabrachial nucleus that express the prodynorphin gene (hereafter, PBPdyn neurons) monitor the intake of both fluids and solids, using mechanosensory signals that arise from the upper digestive tract. Most individual PBPdyn neurons are activated by ingestion as well as the stimulation of the mouth and stomach, which indicates the representation of integrated sensory signals across distinct parts of the digestive tract. PBPdyn neurons are anatomically connected to the digestive periphery via cranial and spinal pathways; we show that, among these pathways, the vagus nerve conveys stomach-distension signals to PBPdyn neurons....
