Zusammenfassung: | A method for carrying out a chemical transformation of a target molecule immobilised at a given location on a solid support is provided. The method is characterised by the steps of (a) generating a stream of microdroplets each comprised of a medium capable of causing the chemical transformation to occur; (b) contacting each microdroplet in turn with the target molecule at the given location and for a given period of time under conditions where the chemical transformation can occur, wherein the method further comprising the step of synchronising the microdroplets flow over the particle; (c) at the end of the given period removing the microdroplet from the given location; wherein the microdroplets are caused to move over a surface chemically modified to have areas of locally increased level of wettability and wherein such an increase in wettability is used to mediate the wetting of the microdroplet around the target molecule; and wherein the electrowetting or optically-mediated electrowetting effects are used to locally modify the wettability of a region of the surface around the particle. |
