Densely packed co-adsorbed ultrathin mono molecular layers of short tri(ethylene glycol)-alkanethiolate (for repelling proteins) and maltoside terminated alkanethiolate (for capturing lectin) provided an extremely high signal to noise ratio surface: the repelling molecules, which had two different functions (highly flexible-hydrophilic arm and rigid packing tail group), worked as “nano barriers” in the recognition monolayer.
Provided is a capsule having a shell of material that is a supramolecular cross-linked network. The network is formed from a host-guest complexation of cucurbituril (the host) and one or more building blocks comprising suitable guest functionality. The complex non-covalently crosslinks the building block and/or non-covalently links the building block to another building block thereby forming the supramolecular cross-linked network. The capsules are obtained or obtainable by the complexation of a composition comprising cucurbituril and one or more building blocks having suitable cucurbituril guest functionality thereby to form a supramolecular cross-linked network.

A gold nanoparticleâpolymer composite material has been prepared in water using cucurbit[8]uril as a supramolecular âhandcuffâ to hold together viologen-functionalised gold nanoparticles and a naphthol-functionalised acrylamide copolymer.
