Aptamer raman signal
WebRaman signal stems from photon scattering caused by a molecule’s electric cloud. The signal is unique for each analyte. While Raman scattering signal was originally too low for sensitive detection, the addition of colloidal nanoparticles offers enhanced signal generation and improved sensitivity. Web5 nov 2024 · Preparation of Self-Assembled Raman Signal Molecules Same amounts of Vibrio parahaemolyticus aptamer (10 μM) and TECP (1 mM) were mixed. Then, the mixture was stood for 30 min. The 40-μL mixture was added to 1 mL gold nanoparticle solution and reacted for 12 h at 180 rpm on a 37 °C oscillator.
