19. 3 and i-PrOH and dried in a gentle stream of nitrogen.
20. 2 plasma etch for 30 s. Finally, the resist was removed with acetone, and the sample was further cleaned in acetone, isopropyl alcohol, and deionized water.
21. Array imaging was performed using the Cy3 channel of an Affymetrix 418 array scanner at a resolution of 10 μm.
22. The oxide patterns were amine-terminated by reaction with 3% aminopropyltriethoxysilane (APTES) in 95/5 v/v memanol/water for 1 h under stirring. The resulting surfaces were washed with methanol (two times) and isopropanol and then dried in a gentle stream of nitrogen.
