Fluorescence lifetime imaging microscopy along with non-Euclidean phasor analysis for visualization of drug distribution of a topical drug in human facial skin (Conference Presentation)

Paper Abstract

We recently proposed a method for selective visualization of topical drug distribution within human facial skin using two-photon fluorescence lifetime imaging along with non-Euclidean phasor analysis as a pharmacokinetics and pharmacodynamics imaging toolkit. In order to improve the efficacy of topical drug delivery toward the treatment of inflammatory acne, we have now developed a combination topical gel containing both minocycline and a retinoid. Since both drugs have unique fluorescence lifetimes compared to skin, we were able to selectively visualize the distribution of minocycline and the retinoid within ex vivo human facial skin while isolating the contributions of the three components.
