Cost-Effective Tween 80-Capped Copper Nanoparticles for Ultrasensitive Colorimetric Detection of Thiram Pesticide in Environmental Water Samples

Figure 3

(a) UV-vis spectra of Tween 80-functionalized CuNPs in the presence of thiram or other pesticides (the concentrations of thiram were 10 μM and other pesticides were 50 μM); insert a photographic image of selectivity; (b) the bar graphs exhibiting magnitude of change ( was the change in absorbance at 575 nm of CuNPs in the presence of different pesticides); (c) the chemical structures of all the pesticides used for the selectivity study.
