Although real-time PCR (RT-PCR) has become a diagnostic standard for rapid identification of bacterial species, typical methods remain time-intensive due to sample preparation and amplification cycle times. The assay described in this work incorporates on-chip dielectrophoretic capture and concentration of bacterial cells, thermal lysis, cell permeabilization, and nucleic acid denaturation and fluorescence resonance energy transfer assisted in-situ hybridization (FRET-ISH) species identification. Identification is achieved completely on chip in less than thirty minutes from receipt of sample compared to multiple hours required by traditional RT-PCR and its requisite sample preparation. |
