Abstract

A method and apparatus for selectively applying a print material onto a substrate for the synthesis of an array of oligonucleotides at selected regions of a substrate. The print material includes a barrier material, a monomer sequence, a nucleoside, a deprotection agent, a carrier material, among other materials. The method and apparatus also relies upon standard DMT based chemistry, and a vapor phase deprotection agent such as solid TCA and the like.
