First Claim
1. A method for synthesizing a nucleic acid probe array, comprising the steps of:
- (1) providing a substrate;
(2) providing nucleotides or nucleosides that are protected by a photo-protecting group;
(3) directing a light beam onto a plurality of optical transfer elements;
(4) selectively switching the optical transfer elements between substantially light-passing and substantially light-not-passing states in response to gating data;
(5) disposing light passed through optical transfer elements in the substantially light-passing state onto the substrate to provide a reactive group; and
(6) contacting the nucleotides or nucleosides with the reactive group.

Abstract
Systems and methods are described for synthesizing probe arrays of polymers. In one such system, a network server processes customer orders to provide data indicative of at least one probe array sequence desired by the customer to be included in a synthesized probe array. A probe array design and control computer executes a probe array design application that processes the probe and array configuration data to provide probe array design data that is then processed by a manufacturing control application to provide gating data. A probe array manufacturing apparatus selectively switches optical transfer elements between substantially light-passing and substantially light-not-passing states in response to the gating data. Light from those optical transfer elements in the light-passing states strikes one or more biological probe array substrates, thereby enabling selective addition of monomers, such as nucleotides, amino acids or saccharides, to the substrate.
