Outline of Final Research Achievements

Analyses of protein localization and interactions in biological cells are very important on tumor marker targeted medical diagnostics and profiling of some series of diseases. Nanoparticles receive an enormous attention in various biomedical applications since their sizes are similar with biological molecules and structures. Gold nanoparticle (AuNP) possesses unique optical properties based on localized surface plasmon resonance (LSPR) and functionalizability with self-assembled monolayers, thus they have utilized in biosensing and gene delivery applications.
We studied to develop a light-scattering microscopy to probe AuNP internalized into biological cells. The optimum condition for surface modification of AuNPs and intracellular introduction by protein coated AuNP were investigated. Resonant light scattering imaging of AuNPs in a cell was also demonstrated in this study. Cellular uptake and fate of AuNPs were analyzed.
