US Patent 9556360 Silane mixtures

Silanation compositions containing a mixture of two or more silanation reagents, where at least one silanation reagent includes a functional group capable of supporting polymer synthesis and at least one silanation reagent includes no functional group capable of supporting polymer synthesis are useful in modulating the active site density and hydrolytic stability of a surface. These compositions are particularly useful in silanating a surface prior to preparation of a polymer array and provide for increased hybridization results.
