Welcome to Food Materials and Safety Lab, Kyung Hee University. Our interests span a range of topics that are related with the Nanomaterials and its application to the Food Science and other biological research. It includes the development of food grade nanomaterials for the advancement of food system and human health. We are working on a variety of problems related with the synthesis of biocompatible nanomaterials, integration of these materials with biological molecules, and confer them specific functions that can be deliverable to our body through food system. Upon scaling down the size of macroscopic materials into nano scale, the physical principles that determine the overall property of the system changes, and we are utilizing this phenomenon to develop an advanced food materials. We also develop various biosensors (electrochemical, colorimetric and SERS based) for the detection of pathogenic microorganisms in food.
