Overview
The conducting polymer SERS substrate provides not only high signal enhancement due to its strong broadband charge-transfer resonance for large chemical enhancement (as opposed to electromagnetic enhancement in traditional metal-based SERS substrates), but also extraordinarily high reproducibility or substrate-to-substrate, spot-to-spot, sample-to-sample, and time-to-time consistency in SERS spectrum (which is not possible with traditional metal-based SERS) due to the absence of "electromagnetic hot spots" by making the entire surface of the substrate "chemically hot", high durability due to no oxidization, and high compatibility to biomolecules due to its fluorescence quenching capability.
