Figure 4From: Synthesis of mixed-sequence oligonucleotides on mesoporous silicon: chemical strategies and material stabilityReflectivity spectra of APTES- and APDMES-modified PSi microcavities before and after incubation in K 2 CO 3 /MeOH dry. (A) Left: reflectivity spectra of APTES-modified PSi microcavity before (red solid line) and after (dashed line) incubation in K2CO3/MeOH dry at 55°C for different times. Right: corresponding peak shift vs incubation time. (B) Left: reflectivity spectra of APDMES-modified PSi microcavity before (red solid line) and after (dashed line) incubation in K2CO3/MeOH dry at 55°C for different times. Right: corresponding peak shift vs incubation time.Back to article page
