Figure 7From: Synthesis of mixed-sequence oligonucleotides on mesoporous silicon: chemical strategies and material stabilityReflectivity spectra of APTES- and APDMES-modified PSi microcavities before and after the deprotection process. (A) Reflectivity spectra of APTES-modified PSi microcavity functionalized with oligonucleotides before (solid line) and after (red dashed line) the deprotection process with gaseous ammonia solution. (B) Reflectivity spectra of APDMES-modified PSi microcavity functionalized with oligonucleotides before (solid line) and after (red dashed line) the deprotection process with gaseous ammonia solution.Back to article page
