| Research Abstract |
In this research project, we have developed a novel detection system using plastic microbeads, which was coated with gold nanoparticles. The gold nanoparticle coated beads had an electrical conductivity ranging from 30 to a few mega ohm, and ligand coating was made on the gold layer by the self-assembly process. We have confirmed that the formation of a ligand-analyte linkage led to an increase in the electrical resistance of the microbeads.
