These nanoparticles could be used both to fluorescently label biological molecules and as a means to transport them in an electric field, Patten said. A proposed device would use microscopic needles to take up very small volumes of tissue fluid through the skin, mix it with nanoparticles designed to detect particular molecules, and move them to another part of the device for detection.
The work is funded by an NSF grant, the NSF IGERT grant to UC Davis' NEAT (Nanophases in the Environment, Agriculture and Technology) center and a collaborator's DARPA grant. Contact: Timothy Patten, Chemistry, (530) 754-6181, patten@chem.ucdavis.edu .
