Chemical-biological sensing using directly fabricated Au(Pd) core@layer NPs for enhanced SERS detection of low bacterial concentrations
The Au(Pd) core@layer colloidal nanoparticles were paired utilizing the pulsed laser ablation method to reduce a PdCl₂ solution to develop SERS substrates with high enhancement factors for detecting low bacterial concentrations on nanopyramidal Si. Surface plasmon resonance tests were performed using a UV-Vis spectro...
