Nano Structure Research Lab

In our group, Bio-modified electrode fabricate by SAMs(Self Assembled Monolayers) on the electrode surface, at which the aptamer that has specific affinity for the disease marker can be immobilized through the introduction of a functional group. We aim for POCT(Point-Of-Care Test) that can maker early diagnosis through electrochemical analysis(EX : Nyquist plot, Bode plot) by charge transfer reaction on the electrode between marker-aptamer. To control the properties of neural probe, the electrode is modified by different materials. The materials are coated by CVD, electro-deposition, dip coating as their usage. Using the neural probe, we can record signal from nerves and stimulate to the target point. For recording gold, platinum, carbon materials (graphene, graphite) are coated to reduce the impedance and increase the bio-compatibilty. For stimulating the materials with high capacitance or low resistance are coated to reduce the impedance and increase the stabiltiy. This project aims to enhance cognitive functions in humans by stimulating the hippocampus, a deep region of the brain, using various nanoparticles. The hippocampus is a critical area associated with memory formation, and by stimulating it, we aim to improve learning abilities, memory retention, information processing speed, and other cognitive functions. We are synthesizing a diverse range of nanoparticles based on ferrite for this project. These nanoparticles have various characteristics such as size, shape, and composition, and they possess the ability to effectively stimulate specific neural circuits within the hippocampus. The synthesis of these nanoparticles is carried out using advanced materials science technology and chemical synthesis methods, with the goal of developing nanoparticles with optimal
