Sers low concentration
WebPortable surface-enhanced Raman spectroscopy (SERS) capable of various analyte detection with low concentration in a convenient manner shows advantages in sensing … WebIn the case of CaCl2, viscosity measurements resulted in a larger critical concentration, 0.7 mM. It turned out that actin filaments formed in a low concentration of CaCl2 were easily fragmented by shearing force. The higher the actin concentration, the lower the critical metal concentration was.

WebSurfaced enhanced Raman scattering, or spectroscopy, (SERS), is an enhancement technique used to overcome the challenges seen with weak Raman scattering. SERS provides all the advantages of Raman spectroscopy whilst also offering higher sensitivity thorough scattering enhancement and fluorescence quenching. Web12 Oct 2024 · The first SERS substrate was fabricated using the electrochemically roughened metal electrodes, and the main limitations are the reduced control on plasmon resonance as well as the hotspot due to the aggregation with low tenability, even though one can produce a large-area SERS substrate using this technique [ 15 ].
