The present disclosure describes methods of producing colloids of precise sizes and shapes using temperature responsive block copolymers. A method of precise size control of colloids may include producing colloids in a solution of block copolymers, and POSS colloids. The temperature of the solution may be increased at a set rate to swell mesoscopic droplets to a precise size. A method of precise shape control of colloids may include polymerizing colloids in a solution of block copolymers, and POSS colloids and manipulating the temperature of the solution. In particular, the temperature of the solution may be increased at a set rate to swell and polymerize mesoscopic droplets and subsequently decreased at a set rate to collapse the colloids into a precise shape.
