Abstract

This paper reports the design and fabrication of a micromachined silicon pin that serves as a novel contact-printing tool. More specific application is in the DNA and protein microarray field for small and precise droplet printing onto a solid support. Our goal is to develop low cost, high performance silicon pins as simple replacement of the stainless-steel pins used in typical microarray robots. The test results show an average droplet size of 38 μm in diameter, compared with over 100 μm for the commercial pins, as well as more consistent droplet sizes.
