Described here is a device comprising a microfluidic chip and an acoustic transducer external to the microfluidic chip, wherein the microfluidic chip comprises a channel in communication with a microwell having a volume less than one microliter, and wherein the acoustic transducer is coupled to the microfluidic chip via a coupling medium. Also described here is a method for analyzing a cell or a biomolecule, comprising applying a focused acoustic beam to a microfluidic chip comprising a channel in fluid communication with a microwell having a volume less than one microliter, wherein the microwell comprises an aqueous compartment comprising a cell or a biomolecule, wherein the channel comprises a non-aqueous liquid phase immiscible with the aqueous compartment which encapsulates the aqueous compartment in the microwell, and wherein the acoustic beam displaces a meniscus at an interface of the aqueous compartment and the non-aqueous liquid phase thereby ejecting the aqueous compartment from the microwell into the channel as an aqueous droplet.
