Abstract

Here we report on the covalent attachment of photoresponsive azobenzene moieties to cowpea chlorotic mottle virus (CCMV). The modified virus capsids can be reversibly immobilized on cucurbit[8]uril (CB[8]) bearing surfaces via supramolecular complexation.

Abstract

In this communication we report for the first time the use of azobenzene modified glycoconjugates to establish optical control over bioactive ligands at a supramolecular β-cyclodextrin (β-CD) surface. Several studies were conducted to investigate the photoresponsive immobilization of proteins and bacteria on these supramolecular surfaces.

Abstract

A new monolayer platform based on pyrylium has been developed which is reactive towards amine-terminated (bio)molecules. Upon reaction, a switch in fluorescence properties of the monolayer signifies successful immobilization of these molecules.
