摘要： An electrochemical system with reduced limiting-current behavior is disclosed. The electrochemical system is useful for fuel cells and bio-sensors. In part, the invention relates a method of reducing or eliminating limiting-current behavior in the operation electrochemical systems, in particular those with ion-selective membrane or electrochemical electrodes, by spatially reducing the convection near the membrane or the electrode. The invention further relates to electrochemical systems in which micropores, microarrays or pillar arrays are used to reduce convection in comparison to conventional systems without microarrays, micropores or pillar arrays.

摘要： This invention provides a device and methods for increasing the concentration of a charged species in solution, wherein the solution containing the concentrated species is exposed to the environment. Such solution can be formed on a surface or on a tip of a measurement device. The open-environment concentration technique overcomes the disadvantages of in-channel concentration devices, especially by eliminating flow-induced delivery processes that lead to concentration losses. Combined with direct contact dispensing, methods of this invention can be used for various applications such as immunoassay and MALDI-MS.

摘要： The present invention provides a device and methods of use thereof for desalting a solution. The methods, inter-alia, make use of a device comprising microchannels, which are linked to conduits, whereby induction of an electric field in the conduit results in the formation of a space charge layer within the microchannel. The space charge layer provides an energy barrier for salt ions and generates an ion depletion zone proximal to the linkage region between the microchannel and the conduit. The method thus enables the removal of salt ions from the region proximal to the conduit and their accumulation in a region distant from the conduit, within the microchannel.
