Benefits of technology

This patent is about a new way to make better SAMs (semi-solid matrices) by printing reactive peptides onto solid supports. These SAMs are easy to make and can be designed to bind to different targets like cells or antibodies. The method involves using microcontact printing to put the peptides onto the support and keeping them there to bind to the target. The invention has various uses and applications, and the patent also describes a method for making the SAMs. The technical effect of this patent is to provide a new and improved way to make SAMs that are easier to make and can be designed for different targets.

Problems solved by technology

However, these molecules, and the resulting SAMs, can be difficult and / or expensive to manufacture.

Preparation of Patterned SAMs Glass Chip

[0069] A 10:1 (w:w) mixture of Sylgard Silicone Elastomer 184 and Sylgard Curing Agent 184 (Dow Corning Corp., Midland, Mich.) was casted over a master, which was generated by photolithography, and pressure degassed. After sitting at room temperature for 1 hour, the PDMS was cured at 60° C. for 2 hours. The stamp was carefully peeled off the master after cooling to room temperature and rinsed with ethanol. The PDMS stamp was inked by a cotton swab which has been moistened with a 5 mM solution of (1-mercaptoundec-11-yl)hexa(ethylene glycol) (HO(CH2CH2O)6(CH2)11SH) in ethanol. The resulting stamp was placed on the gold substrate (125 ★ gold on a titanium-primed 24×50-2 microscope cover glass) and gentle hand pressure was applied to aid in complete contact between the stamp and the glass chip. After 1 minute, the stamp was peeled off the glass chip and the resulting substrate was immersed directly in a 2 mM solution of (RADC)3 AAAC (SEQ ID NO: 1...

Description

RELATED APPLICATIONS [0001] This application is a continuation of U.S. application Ser. No. 10 / 317,838, filed Dec. 11, 2002, which is a continuation of U.S. application Ser. No. 10 / 071,500, filed Feb. 8, 2002, which is a continuation of U.S. application Ser. No. 08 / 882,415, filed Jun. 25, 1997. The entire teachings of the above applications are incorporated herein by reference.GOVERNMENT SUPPORT [0002] The invention was supported, in whole or in part, by a grant (Grant No. DAAH04-94-G-0407) from the Army Research Office. The Government has certain rights in the invention.BACKGROUND OF THE INVENTION [0003] Organic surfaces have been employed in numerous methods and systems, including as substrates for ELISA, cell and tissue culture. Self-assembled monolayers (SAMs) are a class of organic surfaces manufactured by imprinting a monolayer of organic compounds with reactive moieties onto a solid support under conditions wherein the compounds react with and bind to the solid support in a s...
