Research Abstract

The purpose of this study is to develop gold or platinum nano-colloid particles with high antioxidant activity and functionality by using monomeric and gemini-type amphiphilic dendrimers with one or two alkyl chains and two dendron skeletons and their sugar-modified amphiphilic dendrimers as protected agent. We investigated their solution properties and aggregation behavior, and discussed catalytic activities for their gold or platinum nanoparticles.
