Feasibility of colorimetric detection of biothiols using AgNPRs in 1% human serum (pH 7). (a) Absorption spectra and corresponding photograph images and (b) TEM images of AgNPRs in 1% human serum (pH 7). (1) indicates the absence of target (control), and (2–5) indicates the presence of Hcy, Cys, GSH, and His, respectively. The final concentration of Hcy, Cys, GSH, and His was 6 µM.
