a Variations in the critical pressure of the gas with CTAB concentration. b Ability of different cucurbiturils (CB8 and CB6) to shield the surface activity of the surfactant (CTAB = 0.1 mM). c Influence of the CB8: CTAB molar ratio on the surface tension at different CTAB concentrations. d Influence of the target molecules on the gating behavior of gas in the HG-LGS. Left: Illustration of the gating behavior of the target molecules. Different concentrations of Phe-Gly-Gly modulate the critical pressure of the gas. Right: Critical pressure of gas as a function of the Phe-Gly-Gly concentration at different CB8: CTAB ratios, where, P and P0 are the critical pressures of gas with and without Phe-Gly-Gly. e Effect of the pore size on the critical pressure of the HG-LGS for detection of Phe-Gly-Gly (CB8: CTAB = 1.5: 1, CTAB = 0.1 mM). Error bars represent standard deviations (n = 3).
