Abstract

Replication, precipitation, and amplification: Polymerase or reverse transcriptase induced replication of DNA/RNA on a transducer (electrode or piezoelectric crystal) leads to the ultrasensitive specific electronic transduction of viral genomes. Biotin tags (B) on the double-stranded assembly provide docking sites for a conjugate between avidin (A) and an alkaline phosphatase (AP). Enzyme biocatalysis of substrate (S) to the insoluble product (P), which precipitates onto the transducer (yellow surface), provides amplification in the analysis of the target DNA.
