Methods are provide for modifying a solid support, such as a glass slide, by silylating with an agent having the formula H2N-(CH2)n-SiX3 where n is between 1 and 10, and X is independently chosen from OMe, OEt, C1, Br, or I, then activating with a crosslinking reagent, followed by reacting with an amine- containing polymer. The support can optionally be reacted wiht a crosslinking reagent again. The support thus modified may be used to make arrays and microarrays where a plurality of targets are stably associated with the support and arranged in a defined manner.

L'invention concerne des procédés pour modifier un support solide, tel qu'une tranche de verre, par silylation avec un agent de formule H¿2?N-(CH¿2?)¿n?-SiX¿3?, dans laquelle n oscille entre 1 et 10, et X est choisi indépendamment de OMe, OEt, C1, Br, ou I, puis par activation avec un réactif durcissable et par mise en réaction avec un polymère contenant de l'amine. Le support peut éventuellement être remis à réagir avec un réactif durcissable. Ce support ainsi modifié peut être utilisé pour effectuer des échantillons et des micro-échantillons, où une pluralité de cibles est associée de manière stable avec le support et disposée selon des critères définis.
