<p>There is disclosed process for preparing a substrate 1. Process for preparing a substrate having thereon sites reactive with the reactive groups of a molecular probe, the process comprising the steps of applying to the substrate surface a material comprising one or more reactive sites having an activated ethylenically unsaturated double bond of the formula I: Wherein, if n= 0, m= 1, X3 is carbon and X1 is nitrogen, the bond between them being triple, and X4 does not exist; if n= 1, m= 1, X3 is carbon and X1 is oxygen or sulphur, the bond between them being double, and X2 is oxygen or sulphur or nitrogen substituted by an organo substituent; if n= 1, m= 1 or 2, X3 is sulphur and X1 is oxygen, the bond between them being double, and X2 is nitrogen substituted by an organo substituent; R¿1?, R2, each independently represent hydrogen, hydroxyl or organo group, R3 and R4 each independently represent hydrogen or organo group, eventually containing a silicon atom R1 and R2 being not linked to R4. and, in a further step, of covalently binding the reactive group of the molecular probe to the activated ethylenically unsaturated double bond of the reactive sites having formula I. Preferred activated unsaturated moiet(ies) comprises unsaturated ester moiet(ies) such as (meth)acrylate moiet(ies). Preferred probes comprise amino groups thereon. Preferred strong links are covalent bonds. Preferred linking reactions are Michael addition reactions. The substrate having probes deposed thereon may be used to interact with a target. Other aspects of the invention relate to substrates and multi-reactive systems (such as microarrays) so prepared; uses thereof; and products and information obtained therefrom.</p> |
