Abstract:
Fluid transport approaches are described that operate without the need for precise displacement of an actuator and with little or no sensing in the flow path. In certain implementations, a gas phase in a fluid reservoir is compressed by a pressure source such that releasing the pressure, such as by opening a valve to an intermediary conduit, displaces fluid to the intermediary chamber. Closing that fluid path and opening a different fluid path to a chamber at ambient temperature causes the fluid to be displaced to the chamber.

Abstract:
Techniques and devices are provided related to insert assemblies that may be used in conjunction with microfluidic devices. In one embodiment, the insert assemblies include a functional material, such as a solid stationary phase, that may be coupled to a microfluidic pathway via the insert assembly. In this manner, solid stationary phase materials that may be challenging to directly apply to a microfluidic device may be separately enclosed inside the insert element prior to assembly into a microfluidic device, such as a microfluidic chip.
Abstract:
Disclosed are microfluidic devices and kits for containing radioisotopes. The devices and kits comprises at least one confining geometry having a cross-section dimension below the beta(+) or beta(-) range of a radioisotope, when containing the radioisotope configured in such a way that neighboring segments of the confining geometries are isolated from its nearest neighbor such that no measurable kinetic positron energy transfer occurs between the segments when containing the radioisotope. Methods of storage and synthesis of radiopharmaceuticals are also disclosed. In another aspect, the present invention relates to methods of storing radiotracers and synthesizing radiopharmaceuticals, using the aforementioned device. The radiotracers and radiopharmaceuticals comprises 18 F, 11 C, 14 C, 99m Tc, 123 I, 125 I, 131 I, 68 Ga, 67 Ga, 15 O, 13 N, 82R b, 62 Cu, 32 P, 89 Sr, 153 Sm, 186 Re, 201 Tl, 111 In, or combinations thereof.
