The interface of silica nanochannel of 10 nm was studied by molecular modeling and experimental methods. Molecular Dynamics study on glucose solution revealed that 2–3 nm of interface solution to silica walls has reduced glucose diffusivity. That reduction affects the effective diffusivity of glucose in silica nanochannel. Experimental results show Fickian-like release of glucose through 13 nm nanochannel. Molecular modeling and experimental results suggest that glucose is not sufficiently confined to possess non-Fickian behavior.
