We report a highly sensitive, rapid and reliable method for the detection of Bacillus Anthracis spores at 300/mL using a piezoelectric-excited millimeter-sized cantilever (PEMC) sensor. Antibody specific to Bacillus anthracis (BA, Sterne strain 7702) spores was immobilized on PEMC sensors, and exposed to spores (300 to 3x10 spores/mL). The resonant frequency decreased at a rate proportional to the spore concentration and reached a steady state frequency change of 5 ± 5 (n=3), 92 ± 7 (n=3), 500… CONTINUE READING
