A Schematic diagram of the infection process of influenza A virus entering the cell by first binding to α2-6-linked SG on voltage-dependent Ca2+ channel CaV1.2. B Chemical structures of α2-3/α2-6-linked sialyllactose and lactose. C Molecular design of a functional polymer capable of recognizing sialyllactose; maltose is grafted onto the polyethyleneimine main chain. D α2-6 sialyllactose-triggered globule-to-coil transition of the polymer chains immobilized on the inner surface of the conical nanochannel, which impacts ionic transport passing through the nanochannel.
