SUBSTRATE FUNCTIONALIZATION METHOD FOR HIGH SENSITIVITY APPLICATIONS

摘要

A method for functionalizing substrates such as magnetic beads and glass slides is provided. The method involves providing substrate surfaces with activated polyacrylic acid (PAA) and attaching one or more desired capture probes. Substrates prepared by the method are particularly useful in ultrasensitive detection assays as they exhibit very low specific binding and high binding efficiency relative to conventional substrates.
