Detection of biologically important substances using in-situ spectroelectrochemistry
Original language description
Surface-enhanced Raman scattering (SERS) spectroscopy is a technique appropriate for detection of low amount of various analytes. Molecules of analyte can be adsorbed on surface either by physisorption or by chemisorption. For detection of different substances we have used combination of SERS spectroscopy with potentiostatic technique. An in-situ spectroelectrochemical cell was constructed as the three-electrode cell and is designed for connection to Raman probe of Raman spectrometer Dimension P2 (excitation wavelength 785 nm). The SERS-active electrode is based on Pt target electrochemically coated by copper. In our previous studies we demonstrated that copper substrates are suitable for SERS spectroscopy exhibiting surface enhancement factor higher than 105. Copper is from chemical point of view more reactive material than silver or gold that means a variety of analytes can be chemisorbed. Potential values from 0 mV to -1000 mV were applied for each of studied analytes. Analytes were
