Abstract

A process for detecting the sensitivity of one or more polymers and/or of one or more mixtures of polymers to a compound, including the steps of exposing a plurality of individualized micro-deposits including the polymer(s) and/or the mixture(s) of polymers to the compound, and detecting, by interferometry, a variation in appearance of an assembly of micro-deposits exposed to the compound and/or a variation in the dimensions and/or refractive index of at least one of the micro-deposits exposed to the compound, linked to an interaction between the polymer(s) and/or the mixture(s) of polymers and the compound.
