    Snippet: A AuNPs-based colorimetric lateral flow assay (LFA) assay was developed for the detection of HBsAg. This assay relies on the characteristic red color of different sized AuNPs to label HBsAg on an immunochromatographic test strip. A strip composed of a sample pad, conjugation pad, control line, test line and absorbent pad was used to capture HBsAg labeled with AuNPs and the test line becomes red in color. The results showed that the signal visibil.....
    Document: A AuNPs-based colorimetric lateral flow assay (LFA) assay was developed for the detection of HBsAg. This assay relies on the characteristic red color of different sized AuNPs to label HBsAg on an immunochromatographic test strip. A strip composed of a sample pad, conjugation pad, control line, test line and absorbent pad was used to capture HBsAg labeled with AuNPs and the test line becomes red in color. The results showed that the signal visibility of LFA could be improved by increasing the diameter of AuNPs, and ~43 nm AuNP enabled LFA assay with a detection limit of 100 ng/mL [16] .
