  • INSTALLATION AND METHOD FOR DETERMINING THE DIFFUSION PROFILE OF AT LEAST ONE MOLECULE THROUGH SKIN
    Publication number: 20160139020
    Abstract: The invention relates to an installation (1) for determining the diffusion profile of at least one molecule through skin, comprising: a microfluidic chip (4) comprising: a donor compartment (10) intended to contain a test solution comprising the or each molecule; a receptor compartment (12) intended to contain a receptor solution; and a membrane (14) with skin-mimetic barrier properties arranged between the donor compartment (10) and the receptor compartment (12) so that the test solution diffuses through the membrane (14) from the donor compartment (10) into the receptor compartment (12); and an analyzer (8) for measuring a physical parameter of the solution contained in the receptor compartment (12) as the test solution diffuses through the membrane (14), and said analyzer (8) being configured for measuring the physical parameter in the receptor compartment (12), the analyzer (8) being further configured for calculating the diffusion profile of the or each molecule through skin from the measured physi
