Concentration, detection and discrimination of Bacillus anthracis spores in orange juice using aptamer based surface enhanced Raman spectroscopy

Herein, we developed an innovative label free platform for concentration, detection and discrimination of Bacillus anthracis spores. Based on aptamer capture and surface enhanced Raman scattering detection, we were able to detect 10(4) CFU spores spiked in orange juice and discriminate between spores B. anthracis and B. mycoides within 40 min.
