Stratum corneum is the outermost skin layer, and the water content in stratum corneum plays a key role in skin cosmetic properties as well as skin barrier functions. However, to measure the water content, especially the water concentration depth prof

This latest study on in vivo transdermal drug delivery by using opto-thermal radiometry and a capacitance-based fingerprint sensor is presented. A small amount of solvent was applied on the test sites of a volar forearm for a few minutes; opto-therma

Solvents penetration through in vivo human stratum corneum (SC) has always been an interesting research area for trans-dermal drug delivery studies, and the importance of intercellular routes (diffuse in between corneocytes) and transcellular routes

Synopsis We have developed a new method for studying human hair and nail water-holding capabilities by using the condenser-chamber trans-epidermal water loss (TEWL) method. Healthy hair and nail always contain certain amount of water, and they will l

The condenser method with a closed chamber is a novel technology for measuring water vapour flux density, especially for trans-epidermal water loss (TEWL). Although it is originally designed for skin measurements, it can be used for many other materi

Opto-thermal radiometry and the condenser-chamber TEWL (trans-epidermal water loss) method are two novel technologies for in-vivo skin studies. In this paper, for the first time, we combine the measurement results of the two technologies, and study t

We present a theoretical study for opto-thermal measurements on non-homogenerous materials, namely the optical gradient materials and the thermal gradient materials. We first present a general opto-thermal mathematical model for gradient materials. T

The use of opto-thermal transient emission radiometry (OTTER) for non-invasive measurements of water concentration depth profiles in human skin is important for developing an understanding of its barrier function. In this paper, a new inverse method

Optothermal transient emission radiometry (OTTER) was used to determine the mean surface hydration and the hydration profile of three mutants (beefsteak, slicing and salad) of harvested tomatoes (Lycopersicon esculentum) that were kept under ambient

We report a new spectroscopic technique that combines step-scanning Fourier transform infrared spectroscopy with opto-thermal transient emission radiometry (OTTER) in order to provide near-surface depth-resolved spectra in the range 700-1800 cm(-1).
