Nanotechnologies associating surface resonant light to probe the displacement of interfaces and the sedimentation of fragmented matter: towards blood viscosity measurements by resonant photonics
Résumé
Resonant light signals have already proven their ability to follow phase transitions of products in biology [1], agri-food and cosmetics [2]. These phase transitions may or may not present an enthalpy variation, being only a conformation/structural change [2] of the product. We will present that the processing of such resonant light signals could recently allow the detection of interface approach between fluids [3], the sedimentation rate of nanoparticles in colloids [4]; this kind of application is useful in many areas as galenic pharmacology with colloids, energy and electronics with oils, agri-food with cream and foam. We will conclude with the application of such resonant surface light technology to possible differential measurements of blood viscosities (poultry, goat, human) [5].
