1. A method of packaging probe arrays, comprising the steps of:
- forming a plurality of probe arrays on a surface of a rigid and flat substrate having a plurality of alignment marks disposed on the surface, by coupling selected monomers or biopolymers to said substrate whereby a plurality of different biopolymer sequences are formed at different known locations each having area of less than 10-1 cm2 on said surface of said substrate;
separating said rigid and flat substrate along lines determined by the alignment marks into a plurality of individual probe arrays, said individual probe arrays comprising greater than 100 probes; and
inseparably mating at least one of said individual probe arrays to a housing, said housing comprising a reaction chamber, said reaction chamber comprising an inlet for flowing fluid into said reaction chamber, and said at least one probe array being in fluid communication with said reaction chamber.
