Sangmin Jeon 교수의 연구실은 나노입자 기반의 생물학적 감지 기술과 에너지 변환 소재 개발에 중점을 두고 있습니다. 금속 나노클러스터와 자기 나노입자를 활용한 감염병 원인 병원체 및 종양 마커의 고감도 진단 기술을 개발하며, 동시에 태양열 증발 소재로서의 다공성 탄소 구조체의 수송 메커니즘을 연구하고 있습니다. 특히, 나노입자 상호작용을 기반으로 한 동적 빛산산란 기반 진단법과 원자력현미경에서의 진동 유도 마찰 저감 메커니즘에 이르기까지 다학제적 접근을 통해 응용 기초 연구를 수행하고 있습니다.

A novel method was developed for the detection of <italic>Salmonella</italic> bacteria using gold-coated magnetic nanoparticle clusters (Au/MNCs) and lateral flow filters.
We developed a 3D solar steam generator with the highest evaporation rate reported so far using a carbonized luffa sponge (CLS). The luffa sponge consisted of entangled fibers with a hierarchically porous structure; macropores between fibers, micro-sized pores in the fiber-thickness direction, and microchannels in the fiber-length direction. This structure remained after carbonization and played an important role in water transport. When the CLS was placed in the water, the microchannels in the
A facile and sensitive immunoassay protocol for the detection of alpha-fetoprotein (AFP) was developed using gold-coated iron oxide magnetic nanoclusters and dynamic light scattering (DLS) methods. The increase in the average particle size due to AFP-mediated aggregation was measured using DLS, and the detection limit was better than 0.01 ng mL(-1).
We studied the effect of periodic normal (out-of-plane) surface vibrations on friction in an atomic force microscope experiment. Vibration frequency was varied in the range of 1–100kHz, and vibration amplitude was varied in the range of a few nanometers. We observed a reduction of a few orders of magnitude in friction coefficient due to the periodic vibrations. Friction reduction is over a wide range of vibration frequencies and amplitudes. Very low values (of the order of 0.01) of friction coef
