演 題：Synthesis and applications of multicomponent nanoparticles
講演概要：Over the past several decades, a great deal of research in nanoscience has been on
multicomponent nanoparticles. The incorporation of multiple chemical species into a single particle
can provide multiple functionalities, as well as new properties not observed for the individual components.
However, understanding how different molecules can be assembled into a single solid phase is not always
straightforward, since the formation often occurs under inhomogeneous and/or nonequilibrium conditions.
My lab has been studying a number of methods for creating multicomponent nanoparticles for different applications.
I will present an overview of the issues involved in getting multiple components to colocalize into nanoparticles
and show several examples from my lab: the synthesis of nanoparticle contrast agents for magnetic resonance
imaging using miniemulsion polymerization, the formulation of novel copolymer nanoparticles for treating acute
kidney injury, and the synthesis of liquid-core polymer-shell nanocapsules using the reprecipitation method.
