a Time-dependent rheology showing the autonomous change in mechanical strength in the unbuffered system. b Time-dependent change in fluorescence intensity in the unbuffered system using DPH (λex = 350 nm). c pH-dependent color change of Methyl Red indicator in unbuffered system. d Time-dependent 1H NMR in unbuffered medium. e Time-dependent HPLC showing the generation of C in unbuffered system. Inset shows the first derivative plot for better visualization of the increased hydrolytic rate (blue and gray bands). Error bars represent standard deviations of triplicate experiments. f Concentration of BC required for gelation at different pHs (red square) and concentration of BC in unbuffered system measured from HPLC at different pHs (black square).
