1. A method for making array plates comprising:

  • (a) coating a glass support surface with a positive or negative photoresist substance which is subsequently exposed to light and developed to create a patterned region of a first exposed surface and a photoresist coated surface on the support;

    (b) reacting the first exposed surface with a fluoroalkylsilane to form a stable fluoroalkylsiloxane hydrophobic matrix on the first exposed surface;

    (c) removing the photoresist coat on said photoresist coated surface so as to form a second exposed surface; and

    (d) reacting the second exposed surface with a hydroxy- or aminoalkylsilane so as to convert the second exposed surface to a derivatized hydrophilic binding site region and thus form the array plate.
