Methods for applying small volumes of reagents |
摘要 |
Methods, devices and apparatus are disclosed for carrying out multiple chemical reactions, such as in situ synthesis of polynucleotides, on a surface comprising an array of discrete sites. Molecules are deposited at a predetermined number of the discrete sites on the surface for reaction at the discrete sites. The surface is positioned relative to an outlet of a fluid ejection device, which is activated to dispense a small volume of a fluid through the outlet to the surface to provide uniform coating of a continuous region of the surface comprising a multiple of the discrete sites. The fluid is dispensed as uniform particles having a diameter such that the uniform particles form a sheet to coat the continuous region of the surface. In one embodiment of the present invention, liquid is dispensed as uniform particles through a fluid ejection device activated by means of ultrasonic energy. The invention has particular application to the in situ synthesis of polynucleotides in arrays on a surface.
