Dr. James B. Delehanty, Ph.D.

Our laboratory develops nanoparticle systems for a variety of applications including imaging, sensing drug delivery, and control of cellular function.  This talk will detail several nanoparticle-bioconjugate systems we have realized for use in biology and biomedicine.  These include semiconductor nanocrystal systems for enhanced visualization in in vivo electrophysiology, imaging the developing nervous system, voltage sensing in neurons and enhanced drug delivery to drug-resistant cancer cells.  Additionally, the use of photothermal gold nanoparticles to stimulate neuronal cells will be discussed.
