Pack of 5 Gold SERS Substrates (5 mm x 5 mm Active Area) – Ultra-Sensitive Surface Enhanced Raman Scattering Substrates with Fluorescence Quenching & Broad Excitation Range
Description
A pack of 5 gold SERS substrates with a 5 mm by 5 mm active area.
Part Number: P-Au-SERS-5mm
Nefer Ka’s gold SERS substrates are engineered for ultra-sensitive Surface Enhanced Raman Scattering (SERS) spectroscopy, offering high reproducibility, uniform signal, and minimal background noise. Fabricated using a scalable, patented technology, these nanocaps-based SERS substrates enable molecular detection at extremely low concentrations (nano-molar sensitivity demonstrated). Ideal for chemical analysis, biosensing, environmental testing, and forensic applications, Nefer Ka’s gold nanocaps SERS substrates provide consistent, high-quality Raman signal enhancement, making them a valuable tool for researchers and industry professionals.
Fluorescence quenching: One of the key advantages of Nefer Ka’s Surface Enhanced Raman Spectroscopy (SERS) substrates is fluorescence quenching, which allows for higher signal-to-noise ratios even at short excitation wavelengths. As the intensity of a Raman signal is inversely proportional to the excitation wavelength (λ_exc) to the fourth power (I_Raman∝1⁄(λ_exc^4) ), the use of a shorter excitation wavelength is essential to obtain a large signal-to-noise ratio. However, as the excitation wavelength decreases, fluorescence from the analyte under test becomes problematic. Nefer KA’s SERS substrates resolve this problem by quenching the fluorescence while operating at a shorter wavelength. Raman measurements of Rhodamine B and Rhodamine 6G using Nefer Ka's substrates at the excitation wavelength (λ_exc = 632 nm) exhibit minimal fluorescence.
Broad excitation bandwidth: Nefer Ka’s SERS substrates can be excited within a wavelength continuum that spans the range for from 500 nm to 800 nm.
Flexible substrates: Nefer Ka’s pack of 5 SERS substrates are produced on a flexible polymer and are then affixed to a rigid glass microscope slide for ease of handling. If required, the SERS substrates can instead be affixed onto a larger flexible polymer substrate.
