Research Interests

Nanobiofabrication, Biosensing, Smart Biomaterials
Professor Hyunmin Yi's general research interests are in understanding and exploiting selective and programmable properties of biological materials and interactions for controlled fabrication of functional materials at micro and nano scales (nanobiofabrication) such as multifunctional biosensors, biophotonic devices and precious metal nanocatalysts for biomedical, environmental and biotechnology applications.

Nanobiofabrication with Genetically Modified Viral Nanotemplates
Professor Yi's group has developed efficient synthesis routes for small (1-2nm) palladium, platinum and silver nanoparticles via spontaneous reduction with genetically modified tobacco mosaic viruses (TMV) as biologically derived nanotubular templates. These biotemplated nanoparticles exhibit very high catalytic activity and stability for a range of catalytic reactions in environmental and chemical synthesis applications. Combining various characterization techniques (e.g. SAXS, AFM, hrTEM, XPS, ICP), robust assembly schemes and reaction kinetics studies, his group aims to gain deep understanding of nanoparticle formation mechanisms, nanocatalyst synthesis-structure-reactivity relationships and selective reaction pathways.

Biofabrication of Biosensing Platforms with Smart Biomaterials
Professor Yi's group develops facile fabrication-conjugation strategies for multifunctional hydrogel microparticles by integrating robust soft-lithographic micromolding techniques, smart biomacro/supramolecules and bioorthogonal conjugation chemistries. Specifically, his group utilizes a simple and robust replica molding technique to fabricate highly monodisperse and shape-controlled biopolymeric-synthetic hydrogel microparticles that possess unique core-shell structures and abundant primary amine functionality rising from the naturally derived polysaccharide chitosan. In-depth conjugation kinetics studies are being carried out on biomolecular conjugation reactions between these hybrid hydrogel microparticles and functionalized proteins via bioorthogonal chemistries such as strain-promoted cycloalkyne-azide (SPAAC) reaction toward rapid protein sensing and bioprocess monitoring applications. TMV templates drastically enhance the biomolecular probe density by serving as a nanobiotemplate with a robust structure, controlled dimensions and precisely spaced chemical functionalities for programmable conjugation and assembly.
