1. A process for producing a multiple antibody patterned substrate comprising:
- A. coating an antibody-adsorbent substrate with an antibody-resistant material that is resistant to adsorption of antibodies;
B. removing a portion of the antibody-resistant material to produce a bare site on the antibody-adsorbent substrate having a precise size, shape, and location on the substrate;
C. adsorbing molecules of a selected antibody on to the bare site on the antibody adsorbent-substrate;
D. rinsing the substrate to remove unadsorbed antibody molecules;
E. coating the antibody-adsorbent substrate with more of the antibody-resistant material to cover the bare surface of the substrate between the newly adsorbed antibody molecules; and
F. repeating steps B through E until each of the antibodies has been adsorbed at its specific site on the antibody adsorbent substrate.

Abstract
A patterned multiple antibody substrate for use in biosensors or immunosensors is produced by (1) coating an antibody-adsorbent substrate with a material that resists antibody adsorption, (2) using ion beam sputtering, laser ablation, or mechanical scribing to remove the coating at specific sites on the substrate, and then (3) adsorbing specific antibodies at the sites. The substrate is capable of detecting multiple chemical species simultaneously.
