Instantaneous in-line heating of samples on a monolithic microwave integrated circuit microfluidic device

A micro-electro-mechanical system for heating a sample including a substrate, a micro-channel flow channel in the substrate, a carrier fluid within the micro-channel flow channel for moving the sample in the micro-channel flow channel, and a microwave source that directs microwaves onto the sample in the micro-channel flow channel for heating the sample. The carrier fluid and the substrate are made of materials that are not appreciably heated by the microwaves. The microwave source includes conductive traces or strips and a microwave power source connected to the conductive traces or strips.

Microfluidic platform for synthetic biology applications

This invention provides methods and compositions for assembling biological constructs (e.g., plasmids, transformed cells, etc.). In certain embodiments the methods involve encapsulating separate components of the biological construct each in a fluid droplet confined in a fluid channel; optionally mixing droplets from different fluid channels to form a sequenced order of droplets carrying different components of the biological construct in a channel or chamber; and optionally combining two or more droplets each containing different components of the biological construct to permit the components to react with each other in one or more reactions contributing to the assembly of the biological construct.

Microfluidic aspirator and methods of making and using the same

Disclosed herein are devices that include a top chamber including at least one port, a bottom chamber including at least one inlet and at least one outlet, wherein the opening of the at least one inlet is smaller than the opening of the at least one outlet, and a membrane located between the top chamber and the bottom chamber, wherein the membrane is fluidly coupled with the top chamber and the bottom chamber. Also disclosed herein are systems including the disclosed devices. The systems include liquid in one or more of the chambers of the device. Methods of using the devices and systems include producing a vacuum by flowing a liquid through the bottom chamber of the system. Due to the difference in size of the inlet and outlet in the bottom chamber, a vacuum is produced in the top chamber.
