Abstract

The use of a combination of low-cost technologies to both extract and detect anthrax DNA from spores and vegetative cells in two steps within 1 min is described. In a cavity, microwave energy is highly focused using thin-film aluminum “bow-tie” structures, to extract DNA from whole spores within 20 s. The detection of the released DNA, from less than 1000 vegetative cells, without additional preprocessing steps is accomplished in an additional 30 s by employing the microwave-accelerated metal-enhanced fluorescence technique. The new platform technology presented here is a highly attractive alternative method for DNA extraction and the fast detection of Gram-positive bacteria and potentially other pathogenic species and cells as well.
