The linear regression equation was I (μA) =0.0031 C (μM)+1.6968 (R 2 =0.9916), the detection limit (S/N=3) was 15μM. Meanwhile, EDAPbCl 4 @ZIF-67/GCE can effectively detect PCA in green tea and cough syrup.It
3 Electrochemical biosensors for virus detection Electrochemical biosensors are the biosensing devices containing electrochemical transducer that transforms biochemical information and possess advantages as simple instrumentation, high sensitivity, cost-effectiveness and the possibility of miniaturization (Silvestrini ...
Under optimal conditions, the immunosensor has a wide sensitivity range from 1 pg/L to 10 ng/L and low detection limit of 0.33 pg/L (S/N = 3) for HIgG. The immunosensor has high sensitivity, fast assay rate, as well as good reproducibility, specificity, and stability ...
For instance, a NaNO3/NaCl solution, as a milder oxidizing agent in combination with AuNPs functionalized with PEG-based ligands to produce a less compact functionalization layer, has been proposed for the direct electrochemical detection of AuNPs with commercial carbon SPEs [56]. Results o...

Previously, a couple of DNA based bio-electrochemical sensors were developed for the WSSV detection17,18. Zhang et al reported a thiol functional group modified ssDNA (probe) self-assembled monolayer micro-electromechanical system as a sensor electrode and ferricyanide as a transducer for hybridization...
