In this research, combined effect of chlorin e6 and noninvasive 20 kHz, lowpowered ultrasound on melanoma cells is proposed for the first time. The proposed combination incorporates the application of safe low-frequency ultrasound that is used for transdermal drug delivery. We demonstrate that impact of the 20 kHz ultrasound on chlorin e6 leads to strong sonodynamic effect in melanoma cells. We also show that chlorin e6 keeps its monomeric form in the cells and does not aggregate after exposure to ultrasound. We propose a two-step model where sonoluminescence serves as an internal light source for the chlorin e6 photoactivation.

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.
