Idealphotonics' has launched a surface-enhanced Raman spectroscopy (SERS) substrate, a functionalized surface with a nanoscale plasmon resonance structure. Through the synergistic effect of localized electromagnetic field enhancement and chemical enhancement, it amplifies the Raman signal of adsorbed molecules by millions to trillions of times, enabling fingerprint identification and ultrasensitive detection of trace substances.By leveraging the synergistic effect of the plasmon resonance effect (electromagnetic enhancement) of noble metal nanostructures and the molecular-substrate interaction (chemical enhancement), it achieves ultra-strong Raman signal amplification (10⁶-10¹⁴ times) and single-molecule-level detection, combining fingerprint specificity with ultra-high sensitivity.
