Vladislav Yakovlev, professor in the Department of Biomedical Engineering at Texas A&M University, is part of a multiuniversity team researching how electrical and optical pulses can benefit cell absorption of materials, including vaccines.
The team investigated the optical and electrical breakdown of materials. Those effects, which describe material modification in the presence of extreme optical or electrical fields, have been studied since the 1950s. However, the simultaneous application of optical and electrical fields, especially to biologically relevant systems, hasn’t been explored before.
Yakovlev said by investigating the synergistic action of electrical and optical pulses, the researchers were able to promote highly localized breakdown while reducing the threshold for such breakdown.
