Abstract

 

In this presentation, I will begin by discussing the definition and the real meaning of nanotechnology.  Then, I will introduce the methods for making highly luminescence semiconductor nanoparticles and for nanoparticle bioconjugation.  Next, I will focus on my projects for using infrared and upconversion nanoparticles for in vivo cancer imaging, particularly for tumor vascular imaging.  Further, I will present the basic concepts for nanoparticle photodynamic therapy in combination with radiation therapy for cancer treatment.  Finally, I will discuss the application of nanoparticle systems for bacteria and virus detection based on energy transfer and antigen-antibody interaction.

 

 

Refreshments will be served in the Physics Library at 3:30pm, Room 108 Science Hall.
