in this study, a simple and reliable square wave voltammetric (swv) method was developed and validated for determination of diclofenac in pharmaceutical preparations and human serum. the proposed method was based on electrooxidation of diclofenac at platinum electrode in 0.1 m tbaclo4/acetonitrile solution. the well-defined two oxidation peaks were observed at 0.87 and 1.27 v, respectively. cal...

a new competitive immunochromatography (icg) strip test based on polyclonal antibody (pab) conjugated with gold nanoparticles (nps) was developed and its applications for primary screening of immunoglobulin (ig) a in serum were evaluated. nanocolloidal gold as the detection reagent, with an average particle diameter of 20 nm, was synthesized and labelled pab. the antibody-nanocolloidal gold pro...
