摘要: A dropping tool for transferring drops of a liquid onto a substrate wherein a surface of the dropping tool for contact with the liquid has a first region which exhibits an affinity to the liquid to be transferred directly surrounded by a second region which exhibits a lower affinity to the liquid to be transferred than the first region; the topography of the first and second regions and the relative affinities of the first and second regions for the liquid to be transferred being selected such that when the dropping tool is dipped into and then removed from a source of the liquid to be transferred, the liquid adheres to the first region without substantially any adherence of the liquid to the second region. A dropping tool for transferring drops of liquid onto a substrate, the dropping tool comprising a tip, at least one surface tapered towards the tip, and a capillary channel which leads from a position of the tapered surface remote from the tip to a reservoir located within the dropping tool. A method for transferring drops of liquid carried on a dropping tool onto a substrate to form an ordered array of drops thereon wherein the drop of liquid is transferred without contacting the dropping tool with the substrate either directly or indirectly via the drop of liquid.
