Description

As the agency reported it.

In phase I we developed a novel approach to surface enhanced raman spectroscopy (SERS) for detecting human pathogens in cultured bacteria, mixtures of organisms and in oyster tissue. Our approach uses a higher energy laser wavelength (405NM) compared with the lower energy of more the common lasers at 633 and 785NM, a novel mixture and preparation of AG-coated nano-particles passed through a microfluidic mixing platform, and classification of raman spectra with a novel 1D convolutional neural network (CNN). Through serial dilutions of cultured bacteria, the detection limit of the SERS platform was evaluated at a dilution of 1:100, which was equivalent to ~100 CFU/ML and a MPN of 44.8 /ML. In phase II we will further refine the approach and build several units for testing by managers in the field. The…
