A lithium-air flow battery has minimal cathodic product precipitation, thus extending capacity. The lithium-air flow battery includes a flow electrolyte, flowing proximal to the air cathode, the flow electrolyte having little to no intrinsic lithium ion content. Operation of the lithium-air flow battery generates a lithium-ion concentration gradient across the flow electrolyte, with the lowest lithium-ion concentration adjacent to the air cathode. The extremely low lithium-ion concentration at the cathode, combined with the flow condition at the cathode, results in a minimum of solid product accumulation at the cathode, enabling the cathode to catalyze oxygen reduction for an extended duration.

An electrostatic actuator is provide that can include a fluidic line, a first electrode, and a second electrode such that a gate chamber portion of the fluidic line is sandwiched between the first electrode and the second electrode. The electrostatic actuator can also include a pressure-balancing channel in fluid communication with the gate chamber portion where the first electrode is sandwiched between the pressure-balancing channel and the gate chamber portion. A pneumatic valve system is provided which includes an electrostatic gate and a fluidic channel fluidly separate from a fluidic control line. A pneumatic valve portion of the fluidic control line can be positioned relative to a portion of the fluidic channel such that expansion of the pneumatic valve portion restricts fluid flow through the fluidic channel. Methods of using an electrostatic actuator and a pneumatic valve system are also provided.

A microreactor for preparing a radiolabeled complex or a biomolecule conjugate comprises a microchannel for fluid flow, where the microchannel comprises a mixing portion comprising one or more passive mixing elements, and a reservoir for incubating a mixed fluid. The reservoir is in fluid communication with the microchannel and is disposed downstream of the mixing portion. A method of preparing a radiolabeled complex includes flowing a radiometal solution comprising a metallic radionuclide through a downstream mixing portion of a microchannel, where the downstream mixing portion includes one or more passive mixing elements, and flowing a ligand solution comprising a bifunctional chelator through the downstream mixing portion. The ligand solution and the radiometal solution are passively mixed while in the downstream mixing portion to initiate a chelation reaction between the metallic radionuclide and the bifunctional chelator. The chelation reaction is completed to form a radiolabeled complex.
