Pesticide detection on a chip Nanotechnology can be applied to make high-throughput tests, for example for pesticides or other contaminants, that are smaller, faster and more sensitive than conventional assays. UC Davis researchers led by Ian Kennedy, professor of mechanical and aeronautical engineering, and Bruce Hammock, professor of entomology, have made fluorescent nanoparticles of lanthanide oxide and europium oxide that can be coupled to biological molecules and used in antibody-based assays for pesticide residues. The nanoparticles can also be sorted magnetically. The researchers are currently investigating carrying out these assays in microdroplets and in microchannels on etched chips.
These presentations will discuss the development of these fluorescent assays and their possible applications in environmental testing and other areas.
