Description

Researchers at the National Institute of Standards and Technology (NIST) are working on the following technologies: A laser used to modify the charge on the surfaces(s) of a preformed polymeric microchannel (e.g. imprinted, embossed, injection molded, ablated, etc.). It is shown that the fluid flow induced by an electric field applied along the length of the channel increases in velocity in the regions that have been exposed to the laser, therefore indicating a change in the surface charge. Furthermore, the laser can be used to create well-defined spots within the channel that have a higher surface charge than the surrounding material. These spots have been shown to selectively bind proteins in a linear or 2-dimensional microarray pattern. For further information, contact: National Institute of Standards and Technology, Office of Technology Partnerships, 100 Bureau Drive, Stop 2200, Gaithersburg, MD, 20899; This is not an announcement of a contract action or a grant.
