Surface-enhanced Raman spectroscopy (SERS) is a vibrational spectroscopy method with sensitivity down to the level of a single molecule that generates fine molecular fingerprints, enabling for direct identification of target analytes.
The area of study for SERS has been greatly expanded through extensive theory and experimental research, as well as the ongoing advancement of nanotechnology, and has become a popular area of study in the fields of chemistry, physics, materials, biomedicine, and other sciences.
The issues preventing SERS’s use in the actual world are still being worked on, but it has not yet become a standard analytical method.
The Global Surface Enhanced Raman Spectroscopy (SERS) Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
For uses involving Raman spectroscopy, Ocean Optics introduced a new substrate. With the help of a patented gold-silver nanosponge alloy, the new RAM-SERS-SP Surface Enhanced Raman Spectroscopy substrates can generate measurements that are incredibly sensitive and accurate down to the atomic level.
Food safety, anti-counterfeit tagging, biological study, explosives and drug detection, among other uses, are all covered by SERS.
Raman emissions are greatly amplified by SERS substrates, which are very weak signals. Even at parts-per-trillion levels, quick, repeatable measurements of analytes that are SERS-active are feasible.
Raman excitation at 532 nm works best with silver-only SERS substrates, while 785 nm Raman devices work best with gold substrates.
The novel SERS nanosponge substrates work effectively with either wavelength by combining the silver and gold on one substrate.
Furthermore, the sensitivity of the nanosponge substrates is increased to an even higher degree when used with 638 nm Raman excitation.
The deposition of delicate samples is handled more skillfully on RAM-SERS-SP nanosponge substrates than on other choices due to their greater robustness.
The increased sensitivity of these substrates creates new possibilities for SERS applications, especially in addressing the increasing demand for quick, accurate detection of explosives and pesticides.
Ocean Optics now provides 638 nm modular Raman solutions and 638 nm variations of its miniature handheld IDRaman spectrometers to users so they can fully benefit from the sensitivity of the RAM-SERS-SP nanosponge substrates.
