1. A method for preparing a planar, rigid porous glass substrate for attachment of biomolecules, the method comprising:

  • treating a porous glass substrate with a cationic polymer wherein the step of treating said porous glass substrate further comprises;

    coating said porous glass substrate by applying a layer of cationic polymer, the cationic polymer having at least one amino group and dissolved in a buffer at a pH above the pKa of the amino group;

    washing said porous glass substrate such that said cationic polymer electrostatically interacts with pores and surface of said porous glass substrate;

    rinsing said porous glass substrate with water; and

    drying said porous glass substrate.
