Viscoelastic parameters for LPG and silica-binding interactions obtained by fitting the raw QCM-D data using the Kelvin–Voigt model for three sample replicates.

	Thickness (@Req)a nm	Thickness (@kd)b nm	Mass Deposited (@Req) ng/cm2	Mass Deposited (@kd ) ng/cm2	Viscosity (@Req) × 10−4 kg/ms	Viscosity (@kd) × 10−4 kg/ms
LPG/SiO2	7.84 ± 0.22	5.59 ± 0.22	862.95 ± 42.43	615.13 ± 58.06	24.70 ± 0.50	20.57 ± 0.45

^a @R_eq, frequency shift at equilibrium; ^b @k_d, equilibrium achieved after dissociation.
