The invention relates to a method of clamping a substrate on a surface of a substrate support structure. First, a liquid is applied on a surface of the substrate support structure. The surface is provided with a plurality of contact elements. The liquid is applied such that the contact elements are fully covered by a liquid layer. Then the substrate is provided and placed onto the liquid layer. Finally, liquid underneath the substrate is removed such that the substrate rests on the plurality of contact elements and is clamped by means of a capillary clamping force exerted by a capillary layer of the liquid between the substrate and the surface of the substrate support structure.

To provide a PCR method utilizing electrostatic transportation which allows separate control of individual DNA-containing droplets by accurately transporting the droplets, suitably controlling the temperature thereof and allowing a primer to react therewith; a hybridization method utilizing electrostatic transportation which allows rapid and easy detection of hybridization; and devices therefor. A biological sample (droplets containing DNA and primer) (9) is prepared in a chemically inert liquid layer (8), is electrostatically transported by the action of an electrostatic transportation plate (1) with electrostatic transportation electrodes (2) and is heated at a predetermined position of the electrostatic transportation plate (1), thus carrying out PCR.

A liquid zoom lens mounted on a portable terminal is provided. In the liquid zoom lens, a cylindrical body has upper and lower openings to which one pair of lenses is coupled. An auto-focus lens part includes a first insulating liquid layer, a first electrolyte layer, and a first lens. The first insulating layer and the first electrolyte layer are disposed to form an interface at a lower portion of the body. The first lens is disposed on the first electrolyte layer and has a periphery closely attached to a lower portion of an inner periphery of the body. An optical zoom lens part includes a second insulating liquid layer, a second electrolyte layer, and a second lens. The second insulating liquid layer and the second electrolyte layer are disposed to form an interface on the first lens. The second lens is fixed to be movable within the second insulating liquid layer, such that a periphery is closely attached to the inner periphery of the body. Accordingly, the auto-focus function and the optical zoom function can be simultaneously achieved through a single liquid lens whose curvature is varied by the difference of the inherent refractive index between the electrolyte and the insulating liquid.
