Controlled Optofluidic Crystallization of Colloids Tethered at Interfaces
Alessio Caciagli, Rajesh Singh, Darshana Joshi +2
We report experiments that show rapid crystallization of colloids tethered to an oil-water interface in response to laser illumination. This light-induced transition is due to a co…
Optical trapping of colloids at a liquid-liquid interface
Alessio Caciagli, Darshana Joshi, Jurij Kotar +1
We demonstrate the realization of (laterally) optically bounded colloidal structures on a liquid-liquid interface of an emulsion droplet. We use DNA tethers to graft the particles…
Kinetic control of the coverage of oil droplets by DNA-functionalised colloids
Darshana Joshi, Dylan Bargteil, Alessio Caciagli +7
We report a study of reversible adsorption of DNA-coated colloids on complementary functionalized oil droplets. We show that it is possible to control the surface coverage of oil d…
