This study aims to characterize the tungsten-urea analyte indicator electrode. The method used is biosensor potentiometry with urease enzyme immobilization technique. electrode was coated PVA-enzyme glutaraldehyde (GA) 2.9% PVC-KTpClPB- o-NPOE variation of 61% and 66%. Characterization electrodes using SEM-EDS, FTIR XRD analysis. A1-4 sample 1x 1x, 61%. A3-4 3x Likewise, reasoning samples 66% T...

We fabricate α-terthiophene single-molecule junctions (SMJs) and characterize their conductive states by the simultaneous measurements of surface-enhanced Raman scattering (SERS) electronic conductance. The SMJ showed broad conductance distribution due to different portions multiple aromatic rings connected electrodes. SERS spectra obtained measurement vibrational energy C−C stretching mode dep...
