Trifunctional integrated DNA-based universal sensing platform for detection of diverse biomolecules in one-pot isothermal exponential amplification mode

Abstract

A biosensor with all the advantages of ultra-high sensitivity, easy operation, straightforward signal output and universal applicability is introduced. The biosensor was demonstrated to work well in the detection of polynucleotide kinase and DAM methyltransferase, thus providing a powerful tool for clinical diagnosis, drug screening and disease therapeutic assay.
