Abstract
Microarrays are frequently prepared on microscope glass slides. However, glass substrates can break or cut and thus can lead to the contamination of the manipulator during the analysis of biological samples. Alternately, bisphenol A polycarbonate (PC) is shock-resistant and, in addition, is easily eliminated by incineration. We show here that PC is a useful substrate for peptide microarray preparation. We describe in particular the preparation of peptide microarrays on PC using semicarbazide-functionalized silica nanoparticles and in situ semicarbazone ligation with glyoxylyl-peptides. The microarrays were used for the detection of antibodies using fluorescence detection.
