MSE professor Douglas A. Loy has developed microscopic particles of ultraviolet-absorbing plastics prepared by the copolymerization of phenols with aromatic and conjugated aldehydes, like cinnamaldehyde and benzaldehyde, for use as sunscreens.
The resulting sunscreens provide an inexpensive and nontoxic alternative that is capable of absorbing both UV-A and UV-B wavelength radiation.
“Making sunscreens from solid, microscopic particles of UV-absorbing plastics provides better protection for longer than commercial sunscreens, while avoiding exposure to the organic chemicals used in traditional sunscreens,” said Loy.
The new technology, which is available for licensing through Tech Launch Arizona, may be fast-tracked for FDA approval.

Most people aren’t accustomed to hearing “organic” and “semiconductor” in the same sentence. But the words flow naturally for Erin Ratcliff, a University of Arizona assistant professor of materials science and engineering with a chemistry background.
Ratcliff is co-principal investigator on a new research project funded by the National Science Foundation to better understand and improve the viability of organic semiconductor materials, which are being used more and more in the manufacturing of digital display screens and new electronic devices.
The $590,000, three-year award teams Ratcliff with Jeanne Pemberton, a UA Regents’ Professor of chemistry and biochemistry in the College of Science and principal investigator on the study.
