Projects per year
Dr. Guy's research focuses on skin barrier function characterization, transdermal drug delivery, enhancement of percutaneous absorption, iontophoresis, noninvasive biosensing, and the prediction and assessment of skin penetration and topical bioavailability. Dr. Guy has published 350+ peer-reviewed articles and over 70 book chapters. He has co-authored one book and co-edited 7 others. He is also co-inventor of 12 patents. Specific ongoing projects include: measurement of the skin's biomechanical properties at the nanoscale using atomic force microscopy; exploring in vitro - in vivo correlations to faciltate the determination of of topical drug product bioavailability and bioequivalence; the potential of polymeric film-forming systems as sustained release platforms for topical drugs; determination of the disposition of drug and formulation excipients (including nanoparticles) post-application to the skin using coherent Raman scattering and confocal microscopy; examination of a graphene-based biosensor for noninvasive, transdermal glucose monitoring; quantification of dermal absorption from pesticide residues from treated plant surfaces; and derivation and evaluation of predictive models of percutaneous penetration for pharmaceutical and cosmetic 'actives', and for potentially toxic chemicals, which come into contact with skin.
