In the three past decades, tissue engineering allowed to develop skin models with characteristics close ex vivo skin, particularly at level of epidermis. The main function epidermis is protect body against environmental damage (UVs, pollution, microbial pathogens…) and prevent water loss. Keratinocytes, major cellular component epidermis, proliferate differentiate form in fine a physical barrie...

A closed-cell photothermal detector for aqueous analytes has been evaluated at 254 and 678 nm. We used a detector with a water meniscus as a pressure sensor, whose periodic deflection was measured using a low-finesse optical fiber Fabry-Perot interferometer. Performance was compared with a commercial diode array spectrometer and found to be similar for absorption measurements in nonturbid sampl...
