Microcontact Printing Pins (Image 1)
November 16, 2012
These micromachined silicon pins can imbibe solutions of DNA or proteins and, by virtue of their precisely fabricated tips and reservoirs, can accurately and precisely deliver small drops (~200pL) of these solutions to a substrate to create a so-called "DNA Microarray." This work was supported by a grant from the National Science Foundation's Small Business Innovation Research (SBIR) Program. (Date of Image: 2004) [One of four related images.
