A colorimetric immunoassay based on an enzyme inhibitor method

Hollow PDA-Au nanoparticles-enabled signal amplification for sensitive nonenzymatic colorimetric immunodetection of carbohydrate antigen 125

“…Thanks to research efforts contributed by many groups, up to date, there have been various types of immunoassays reported and developed. Typical examples include electrophoretic immunoassay Tang et al 2010;Wangoo et al 2010), enzyme-linked immunosorbent assay Zhao et al 2011b), chemiluminescence immunoassay (Huang et al 2013;Liu et al 2014), fluorescence immunoassay (Garden and Strachan 2001;Hou et al 2012), colorimetric immunoassay (Place et al 1983;Tang et al 2010), mass spectrometric immunoassay ), among others.…”

“…As compared to other counterparts, colorimetric immunoassays have gained increased attention as a promising approach for visual analysis due to their high selectivity and ease of detection (Gao et al 2014;Place et al 1983;Qu et al 2011;Zhou et al 2012). For typical colorimetric immunoassays, detection probes are usually included to monitor the signal change as induced by cancer biomarker.…”

Influence of Iodothyronine Conjugates of Bovine Serum Albumin and Horseradish Peroxidase on Enzyme Immunosorbent Assay of Thyroid Hormones

“…Non isotopic methods adopting enzymes, [1][2][3][4][5][6][7][8][9][10][11] fluorescent, [12][13][14][15][16][17][18] and chemiluminiscent [19][20][21] labels, using competitive format for measuring T 4 and T 3 , were reported. Due to the presence of three available functional groups in T 4 and T 3 , the necessity to select the group that needed to be attached to carrier protein for raising antibodies, as well as the functional group that had to be labeled with the enzyme, needed specific consideration.…”
