Spectroscopy advances dermatological and drug delivery research

The use of Fourier transform infrared (FTIR) spectroscopy in various areas of dermatological and drug delivery research is discussed. FTIR imaging provides information on the protein phase and crystallinity indices. Imaging IR allows mapping of external substances introduced into the skin, thus enabling the spatial relationships between the external substances and internal skin components to be monitored and correlated. The scientists are planning to use liposomes, microscopic lipid membrane vesicles that provide a strategy for topical, dermal delivery of biologically active molecules.
