The Park group, Department of Chemistry, University of Pennsylvania

Goal

To generate multifunctional nanoparticles with controllable structural parameters for their bioanalytical applications

Main Achievements

Synthesized composite nanoparticles of fluorescent core and gold shell that retain the light emitting properties of core particles and the useful surface properties of gold (left).

Demonstrated the use of the multifunctional nanoparticles in a proof-of-concept DNA detection application (right).
