The goal of this project is to design a portable Surface Enhanced Raman Scattering (SERS) analyzer compatible with the paper-based SERS substrate. We seek to reduce the complexity of existing Raman systems while maintaining high sensitivity and accuracy. A photon detector provided by our client, Dr. Singamaneni, will be incorporated into our design. This detector comprises a diffracting grating, a collimator lens, a CCD array detector, and a Wi-Fi transmitter that enables data transfer to external devices for analyzing and displaying the spectrum. Our design will include a sample holder for the paper substrate, an optical pathway that directs the flow of photons to the spectrometer entrance slit, an electrical control system, and safety features that minimize the risk of injury, all encompassed in a ruggedized casing.
The final product to be developed in the future is expected to fulfill the need of adequate spectral resolution for on-site chemical detection in various fields, ranging from academic, pharmaceutical, security, and quality control, while reducing the cost by applying the novel sampling method. The inherent cost-efficiency will make the product a competitive alternative to other spectrometers in the market.
