with defined peptide sequences and from OBOC combinatorial peptide libraries. Although amine loading of blank TentaGel beads was found to be uniform, peptide loading among beads of OBOC peptide libraries varied substantially, particularly for those libraries with long sequences. Construction of OBOC libraries can be monitored with this novel analytical technique so that synthetic conditions can be

azo-enhanced Raman imaging (DAERI), to couple the new class of azo-enhanced Ramanprobes with a high-speed line-scan Raman imaging system. DAERI achieved high-resolution low-power imaging of fast cellular dynamics resolved at ∼270 nm along the confocal direction, 75 μW/μm2 and 3.5 s/frame. Based on the azo-enhanced Ramanprobes with characteristic signals 102–104 stronger than classic Ramanlabels, DAERI
