We experimentally actuate mechanical whispering-gallery modes and wineglass modes in ultra-high-Q microfluidic optomechanical resonators by means of the electrostrictive Brillouin scattering nonlinearity. These devices mechanically oscillate at frequencies ranging over several orders-of-magnitude (7.4 MHz - 11 GHz). We test the devices with sucrose solutions to determine sensitivity of the mechanical frequency to various liquid parameters.
