A signal transmission strategy driven by gap-regulated exonuclease hydrolysis for hierarchical molecular networks

“…3c , lane 9 in A1B16 of Supplementary Fig. 15b ), which is an effective method to inhibit the leakage from the unexpected hydrolysis of Exo III 40 , 41 . The fluorescence of mismatched AB2 is shown in Supplementary Fig.…”

Recent Progress on Nanomaterial‐Facilitated Electrochemical Strategies for Cancer Diagnosis

“…1) A variety of effective strategies have been developed and adopted to synthesize electrochemical cancer biosensors with high sensitivity, fast response, low cost, and ease of carrying; thus, they display good application prospects in practical applications. [150] 2) Nanomaterials have the advantages of strong catalytic activity, good electrical conductivity, high biocompatibility, and large specific surface area, which can effectively amplify the electrical signals of the electrochemical sensor to achieve highly sensitive detection of cancer markers for early cancer diagnosis. Modification of nanomaterials on the surface of the electrode can increase the effective area of the electrode.…”

A sensitive sandwich-type electrochemical aptasensing platform based on Ti3C2Tx/MoS2/MWCNT@rGONR composites for simultaneous detection of kanamycin and chloramphenicol in food samples

“…Aptamers are single-stranded DNA or RNA oligonucleotides that can specically bind to not only various veterinary molecules such as antibiotics, estrogens and sulfonamides but also ions, proteins, and even whole cells. 8,[10][11][12][13][14] Moreover, unlike other recognition elements, e.g. antibodies, it is more physiochemically stable, easier to synthesize in vitro, cost-effective with longer shelf-life and simple to modify.…”
