Abstract: An apparatus for microdroplet generation via liquid bridge breakup, which can efficiently generate microdroplets using liquid bridge breakup without using a complicated mechanical device. The apparatus includes: two substrate plates having respective hydrophilic surfaces; a protrusion provided on a side surface of either of the two substrate plates so as to maintain a predetermined space between the two substrate plates; and a spacer provided on ends of the two substrate plates and spacing the two substrate plates from each other, thereby inducing liquid bridge breakup.

Abstract: A method of printing droplets using capillary electric charge concentration includes: providing a capillary nozzle comprising a back-end part and a front-end part disposed substantially opposite the back-end part; spacing a target member apart from the front-end part of the capillary nozzle at a predetermined distance; immersing the back-end part in a solution; and supplying a voltage to the solution. The back-end part transmits the solution to the front-end part.

Abstract: 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.

Abstract: Provided are a droplet emitting apparatus and a method of emitting droplets using the same. The apparatus includes a solution tank for containing a solution; a nozzle including an opening through which at least a droplet of the solution is emitted; and a voltage generator including a piezoelectric material for generating a voltage by instantaneous pressure application, wherein the voltage generated by the pressure to the piezoelectric material is applied to the solution in order for the at least a droplet of the solution to be emitted through the nozzle.

Abstract: A droplet printing apparatus using capillary electric charge concentration includes a reservoir which contains a solution, a capillary nozzle comprising a back-end part and a front-end part disposed substantially opposite the back-end part, a target member spaced apart from the front-end part of the capillary nozzle at a predetermined distance, and a voltage supplier which supplies a voltage to the solution, wherein the back-end part is immersed in the solution and transmits the solution to the front-end part.
