(a) UV-Vis spectra of selectivity study using different amino acids and the inset show color noticed for CAE-Ag colloid after the addition of nine amino acids (I- Ala, II- Ba, III- Gly, IV- Cys, V- Arg, VI-Trp, VII- Ga, VIII-Val and IX- Ils), respectively. (b) UV-Vis spectra of sensitivity study of L-Cys at different dilutions. (c) - (d) TEM images of CAE-AgNPs after adding L-Cys.
