Abstract

Techniques for the delivery of metered amounts of liquid material include the use of a pin, such as an optical fiber. A sample of the liquid material may be placed on the tip of the pin for delivery to a target area, such as a specific location on a microarray, in a contactless manner. Light transmitted through the pin may be detected to facilitate accurate measuring of the pin's position.
