Photopolymerisation prepared nanoparticles

In recent years, polymeric nanoparticles (PNPs) have found diverse applications in fields such as diagnostics, catalysis and drug delivery. Polymerisation-Induced Self-Assembly (PISA) is a technique that uses a living polymerisation process to drive the self-assembly of PNPs to occur during the polymerisation.

In this research area, we are exploring the potential of synthesising colloidal micro/nanoparticles using visible light mediated CLRP techniques. The use of visible light enables us to finely control the size and morphology of these particles by judicious variation in the irradiation intensity and wavelength. Currently, our research is primarily focused on conducting these photopolymerisations under either (mini)emulsion conditions or dispersion polymerisation conditions (such as PISA).
