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.

Abstract: The invention relates to a method for producing derivatives of O-?-glucosylated flavonoid, comprising at least one step of incubating a glucansucrase with a flavonoid and at least one sucrose, the flavonoid being a flavonoid which is monohydroxylated or hydroxylated in a non-vicinal manner on the B cycle. The invention also relates to novel O-?-glucosylated flavonoid derivatives, and to the use thereof.
