Chemistry of the Air-Water Interface
Field induced droplet ionization facilitates studies of chemical and photochemical reactions at the air-water interface of hanging and acoustically levitated droplets. These have provided important insights into lipid oxidation in molecular biology and aerosol oxidation in environmental chemistry.
Acoustic Trapping of Droplets
An array of 72 40 KHz transducers on two partial hemispheres form a resonant cavity that can levitate droplets, single crystals, and live bugs at nodes in the acoustic field. The mechansism of photodynamic cancer therapy has been elucidated in studies with acoustically levitated droplets.
Astrobiology - Life Detection on Icy Worlds
We work closely with planetary science groups at JPL to conceive and test new instruments and methods for life detection, focusing on icy worlds such as Enceladus and Titan. We are interested in chemistry at the low temperatures of these environments that might lead to molecular precusors to life.
Reagents for Glycan Structure Determination
Glycosylation plays a vital role in biology as one of the most important forms of protein post-translational modification. We have developed novel reagents for glycan capture, isolation and structure analysis.
