The use of alternating current (AC) electrokinetic forces, like dielectrophoresis and AC electroosmosis, as a simple and fast method to immobilize sub‐micrometer objects onto nanoelectrode arrays is presented. Due to its medical relevance, the influenza virus is chosen as a model organism. One of the outstanding features is that the immobilization of viral material to the electrodes can be achieved...
We present, for the first time, a simplified and ultrarapid (∼ 1s) approach for synthesis of microbeads with thiol-functionalized surfaces as potential binding sites, whose density can be tuned according to the ratio of two components in the prepolymer. We verify the successful generation of microbeads and their tuneable surface density resulted from different prepolymer off-stoichiometric ratio....
For the investigation of alternating current electrokinetic effects, a system is presented that allows for the simultaneous observation of fluid flow above and around microelectrodes in all three directions in space. Beside the usual microscopical view from top, lateral observation through the same objective is made possible by two small mirrors that are placed next to the electrodes. Fluid flow and...
