Inactivation of Planktonic Microorganisms by Acoustic Shock Waves

Effects of acoustic shock waves on membrane permeability of Gram-negative bacteria P. aeruginosa for an anionic photosensitizer, such as erythrosine, were studied. Shock waves were generated by rapid local medium heating due to nonradiative relaxation of high electronically excited states of photosensitizer molecules introduced with a high-power laser pulse. It has been shown that upon exposure to shock waves bacteria display an increase in membrane permeability; erythrosine enters the cells, followed by an increase in the photodynamic efficacy on microorganisms.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
