Experimentally selected single-stranded DNA and RNA aptamers are able to bind to specific target molecules with high affinity and specificity. Many analytical methods make use of affinity binding between the specific targets and their aptamers. In the development of these methods, thrombin is the most frequently used target molecule to demonstrate the proof-of-principle. This paper critically reviews...
A binding-induced DNA assembly (BINDA) strategy is able to covert target-binding to amplifiable DNA assembly, thereby extending advances in DNA amplification to the detection of other non-amplifiable molecules. We describe here the concept of solid phase BINDA and demonstrate an approach of detecting proteins using affinity capture of the specific proteins on magnetic beads followed by BINDA. The...
