Monitoring of transdermal drug delivery in skin using the Renishaw Biological Analyser

Detecting the presence and depth of penetration of drug compounds in skin can prove challenging, current technologies fail to achieve adequate penetration through layers of dermal tissue. In this study, Raman spectroscopy using the Renishaw Biological Analyser - RA816 confirmed the presence of a topical compound in the epidermis and reticular dermis with high specificity and sensitivity.
