Congratulations to Kieran whose work on light-responsive Pickering (particle-stabilised) emulsions has been published in Soft Matter. We identify a series of design rules to enable the preparation of light-responsive Pickering emulsions. Using a model system based on silica particles functionalised with a photoresponsive azobenzene chromophore, we demonstrated that reversible emulsification/demulsification can be achieved through the application of light.
