Abstract

Nanocone structures were fabricated by a unique etching-passivation process as the substrates for Surface Enhanced Raman Spectroscopy (SERS). This novel nanostructured SERS substrate allowed reaching unprecedented detection limits (fM of Rhodamin6G; pM of crude peptides), and supported the detection of subtle changes in peptide probe sequences, such as single amino acid phosphosphorylation or mutation. Thus, surface-conjugated peptides could be used as highly potent biological nano-sensors for sensitive profiling of specific protein-mediated chemical changes on nano-sensing probes. We hope such kinase-enzyme activity screening array device and technology will advance all aspects of Life Sciences, and potentially be applied to environment monitoring.
