    Engineering SERS Substrates for Bioelectrochemical Studies

    Philip N. Bartlett*, School of chemistry, University of Southampton, Southampton, SO17 1BJ, UK

    *[email protected]

    Templated electrochemical deposition through close packed monolayers of unform polystyrene colloidal particles followed by dissolution of the template produces structured thin films containing an array of interconnected spherical segement voids. The diameters and organisation of these voids replicate the diameter and packing of the colloidal particles used to form the template and the thickness of the film is controlled by the charge passed to deposit the film. It is thus possible to simply and predictably control the geometry of the film. These structured metal films have interesting magnetic [1], superconducting [2] and optical properties [3] that are determined by their precise geometry. Using templates with diameters between 450 and 1200 nm we are able to produce surfaces that show significant enhancement in surface enhanced Raman spectroscopy (SERS). We have investigated the origins of this surface enhancement by varying the film thickness, template sphere diameter and looking at the angular dependence. We find that the intensity of the SER spectra varies with all of these factors indicating that the precise geometry of the structured surface and the excitation of surface plasmons is important. In contrast to electrochemically roughened surfaces the intensity of the SERS spectra on the structured surface is reproducible from place to place across the surface and from sample to sample. This is a significant potential advantage. The structured surfaces are also robust and stable under laboratory conditions and ideally suited as electrodes for electrochemical SERS experiments. Visible excitation laser sources commonly used in SERS experiments can cause photochemical reactions on the surface as well as fluorescence from the adsorbed molecules, such problems are prevalent in the study of biomolecules. A way to circumvent this possibility is the use of Near Infra-Red (NIR) laser sources. This demands appropriate design of substrates for NIR-SERS in order to obtain the maximum enhancement. Results will be presented for a series of adsorbed analytes and biologically relevant molecules. References [1] P. N. Bartlett, M. A. Ghanem, I. S. El Hallag, P. de Groot, A. Zhukov, J. Mater.

    Single-molecule “Transistors” from Au-nanoparticles to Proteins and DNA in Electrochemical Environment

    J. Ulstrup

    Department of Chemistry, Building 207, DTU, DK-2800 Lyngby, Denmark

    Scanning tunnelling microscopy (STM) to molecular resolution in aqueous solution under substrate and tip double potential control (in situ STM) is established and has recently been extended in our group to ionic liquid media. In situ STM extends beyond imaging, and offers two kinds of tunnelling “spectroscopy”, the tunnelling current/bias voltage relation at constant electrochemical overpotential, and the tunnelling current/overpotential relation at constant bias voltage. These are equivalent to the current/bias and current/gate voltage relations of molecular transistors. In contrast to reported cases of single-molecule transistors, in situ STM-based molecular transistor function operates at room temperature in condensed matter environment. The accessibility of a chemical redox centre in the molecule is crucial in this respect. In situ STM-tunnelling spectroscopy with “on-off” ratios up to two orders of magnitude is established in our group, with transition metal complexes and a redox metalloprotein (Pseudomonas aeruginosa azurin) as prime targets. New results apply to Coulomb blockade effects in Au-nanoparticles (1.6 nm) and to redox-marked oligonucleotides. These quite different systems display molecular electronic amplification features that, however, differ in details of the physical mechanisms. Some perspectives of this will be noted.
