Dr. Dong Sup Kim has focused on developing highly sensitive and selective biosensors grounded in his chemical engineering expertise, and has earned a strong reputation for pioneering innovative sensor platforms based on nanomaterials and organic-inorganic hybrids. From the early stages of his academic career, Dr. Kim has devoted himself to researching sensor technologies capable of precisely detecting trace amounts of biomolecules (proteins, DNA, and metabolites). To achieve this, he has applied a wide range of detection principles, including electrochemical and optical signal transduction methods. More recently, he has proposed next-generation wearable biosensor platforms.
