Encapsulation at the nanoscale

Encapsulation underpins a number of fundamental processes in living systems and occurs on multiple length scales, ranging from the inclusion of small molecules within enzymatic pockets to the compartmentalisation in cells by lipid bilayers.
My group is interested in building and studying novel nanoconfined systems including molecular host-guest complexes, core-shell nanostructures and other self-assembled constructs (e.g. micelles and vesicles).
These nanoconfined systems can be used as nanoreactors for catalysis, nanocarriers for cargo delivery, plus nanoarmour for ultrastable nanoparticles.
