Assessment of a Grism-based spectrometer design for neurotransmitter detection: preliminary results

The sensing of neurotransmitters is currently a difficult task for scientists in the field of biomedical research. The design of a new compact and accurate sensor would benefit greatly the research being done on neurotransmitters. In this effect, optoelectronic sensors are ideal candidate as they are non-invasive and non-reactive to the test sample. This work describes the design, fabrication, calibration, and tests of a new type of neurotransmitter sensor using spectral analysis based on a Grism. This new optical sensor was fitted with a self calibrating algorithm and showed superior resolution as well as a smaller footprint than previously observed.
