Microarray technologies have received considerable attention owing to the fact that they serve as effective tools for high-throughput analysis of boimolecular interactions and the identification of bioactive substances that bind to biomolecules. Most of the current methods used to construct microarrays rely on the immobilization of substances on properly derivatized surfaces. Among various functional groups used for this purpose, the N-hydroxysuccinimide (NHS) ester group has been largely employed since it can be readily reacted with amine or hydrazide functionalities in substances of interest. However, the NHS ester group is usually introduced onto the surface of a glass slide by employing inconvenient and time consuming multi-step processes. In recent studies, it was developed an efficient, single step method for derivatization of glass surfaces with NHS ester groups that takes advantage of an acid-mediated reaction of NHS ester functionalized dimethallysilanes with silanols on the glass surface. Conditions for the surface modification procedure that utilize TfOH rather than Sc(OTf)3 were found to be superior. Protein and RNA-binding experiments show that glass surfaces modified by employing this method are suitable for efficient immobilization of various substances that are appended by amine, hydrazide and alcohol functionalities. The newly developed acid-mediated, glass surface modification method should be generally applicable to the preparation of various functional group-modified surfaces.
