Food quality is a major issue for public health, as many outbreaks of foodborne illness are associated with consumption of "fresh" food contaminated by bacteria. Current methods for pathogen detection are time consuming and complicated. SERS is one of promising methods for real-time rapid detection of foodborne pathogenic bacteria. Normal Raman scattering utilises the inelastic scattering interaction of excitation light and vibrational modes of molecular bonds and therefore obtains unique "fingerprint" peaks to identify the particular molecule(s) (Vibrational spectroscopic technique). Surface-enhanced Raman spectroscopy (SERS) is a highly sensitive Raman detection technique based on metallic nanostructured substrates. Many different methods have been employed to produce these nanostructured noble metal arrays, e.g., colloidal lithography for discrete nanostructure arrays, colloidal mask templates for nanostructured films, nanovoid arrays from electrodeposition and electron beam lithography. However, these methods have various issues in expense, efficiency, reproducibility or quantity production. To overcome these disadvantages, we developed a novel method using nano-imprinted polymer substrates and an oblique angle vapour deposition (OAD) method. The project's aim, by collaborating between multiple disciplines in Scottish Universities, is to optimise our substrates' nano-structure and develop a rapid, non-invasive, non-destructive and reliable detection method for foodborne pathogen detection. These sensor substrates have significant advantages of low cost, high efficiency and reproducibility in large-scale production. Initial bacteria measurement with existing templates has shown encouraging results. This technique will reduce risks to national security in terms of intentional food contamination and public health. It is also felt that the initial research would lead to research council or Scottish Government funding.
