Photo acids and bases are compounds that undergo chemical transformations upon exposure to light, invoking the ability to control chemical processes with both spatial and temporal precision. In materials science, photo acids and bases have been used in the development of photoresists for microfabrication processes, enabling the creation of ever-smaller semiconductor chips and electronic devices. Additionally, they can be used in life sciences to modulate pH in organelles, usually via two-photon excitation. Some of their applications are for 3D optical data storage, modulation of ion transport in acid-sensitive ion channels, and circumventing chemoresistance of certain cancer cells.
Dr. Belfield is one of the pioneers in two-photon absorbing materials, two-photon photochemistry, and two-photon photophysics. His research spans a number of disciplines including organic, polymer, and physical chemistry, as well as optics, optical microscopy, and bioimaging. Dr. Belfield currently has funding from the National Science Foundation, the National Institutes of Health, the National Academy of Sciences, and the Arnold and Mabel Beckman Foundation with support for a Postdoctoral researcher from the James and Ester King Foundation for Biomedical Research. In 2011, he received the Pegasus Professor award, the highest distinction awarded to a faculty member at the University of Central Florida.
