Oligonucleotide microarray fabrication by chemical synthesisusing photoacid generators in solid films could have advantages over existing methods, but has not matched the accuracy of conventional synthesis where detritylation is performed with acidsolutions. To address this problem, we explored the kinetics and equilibria of nucleoside detritylation in solid films, using trichloroacetic acid (TCA)
