It was found that such zeolites can be obtained using a zeolite synthesis method comprising the preparation of a gel or solution for the synthesis of a zeolite, said gel or solution comprising appropriate amounts of (i) a conventional monomeric or polymeric silica source and (ii) a molecular template as a microstructuring agent, characterized in that said gel or solution further comprises an organosilane compound having limited self-assembling capacity.

Preferably, prior to reaction of the first protected amino acid, the organofunctional silica is reacted with at least one linking compound to form a linker-modified organofunctional silica with which the first protected amino acid is reacted. A method for preparing an organfunctional silica by the co-hydrolysis of an alkyl silicate and an organofunctional silane is depicted below. The wavy line represents the silicon atom on or within the resulting silica material formula (I). A reaction of a protected amino acid with an organofunctional silica to provide a tethered protected amino acid is depicted below formula (II).

The method of synthesis of such sensors preferably includes use of controlled free radical polymerization techniques, which allows for controlled architecture polymers to modify the surface of the substrate, and the use of monomers possessing functional groups which do not require activation prior to probe attachment. In this manner functional groups in the polymer chain are removed from the surface, which allows for solution chemistry to be more realistically reproduced with the benefits of a solid bound probe.
