LATEX BASED ADSORBENT CHIP

摘要

The present invention provides an adsorbent chip, which includes three components, a substrate, an intermediate layer of linker arms and an adsorbent film, which is attached to the linker arms. The adsorbent film is made up of a plurality of adsorbent particles, each of which includes a binding functionality. The invention also provides a method of making the chips of the invention in which the substrate-intermediate film cassette is formed and the adsorbent film is subsequently immobilized thereon. When the adsorbent film is from the same preparation across a particular batch of chips, the chips provide for the acquisition of data that are highly reproducible from one chip to the next throughout the particular batch of chips. Additionally, the invention provides methods for using the chips to perform assays.
