The porous carbon 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.
Combine with the BaySpec’s SERS reader – a mini wearable analyzer, which provide a full analytics solution. SERS readers feature proprietary miniaturized optics, highly efficient detector, and maximum sensitive with ultrafast acquisition. The full fingerprint coverage and high resolution delivers the best-in-class performance in a variety of applications, from detection of illicit drugs, toxic industrial chemicals (TICs), pesticides, urine drug testing, microplastic detection, chemical warfare agents, biological warfare agents, explosives, infectious disease sensing and many other detection applications.
