I will describe a new program of measurements in fundamental physics using optically levitated dielectric microspheres. While the investigation of gravity at short distance is the primary goal of this program, I will show an array of intermediate results, including searches for millicharged particles, Chameleon fields and techniques to manipulate the various degrees of freedom of the trapped microspheres.
