제목 Sensitive multiplexed Immunoassay using Silica coated gold nanoparticle based on MEF effect in shape-coded hydrogel
초록 MEF has been widely studied to improve the sensitivity of protein based bioassays. MEF is a well-known technology, wherein at the certain distance between metallic nanoparticle and fluorophores result in fluorescence enhancement. Silica coated goldnano particle is a promising candidate for fluorescence biosensing owing to their high enhanced-fluorescence intensity and low toxicity. In addition, hydrogel is the three dimentional structured soft and elastic material that absorbs water providing biological enviroment. In our study, AuNps were coated with different thickness of silica to optimize the MEF effect. We also prepared different shapes of PEG hydrogel microparticles for multiplexed suspension immunoassaays. After confirming immobilization of IgG on the surface of maximized MEF effect SiO2@AuNPs, entrapped in the different shape of hydrogel microparticles. It is expected to utilize for high sensitive multiplexed immunoassay detecting various analytes.
