(A) Functionalized MoS₂ interactions with different charges and different proteins. (B(a and b)) Enzymatic activity of ChT as a function of inhibitor concentrations in sodium phosphate buffer (pH 7.4) using SPNA as a substrate. The activities were normalized to that of only ChT. (c and d) Enzymatic activity of β-Gal as a function of the same inhibitor concentrations in sodium phosphate buffer (pH 7.4) using o-nitrophenyl-β-D-galactopyranoside as a substrate. The activities were normalized to that of only β-gal. Reprinted with permission from Karunakaran S, Pandit S, De M.
