A MICROFLUIDIC MICROARRAY WITH HIGH SURFACE AREA ACTIVE REGIONS

摘要

Described herein is a method of providing three dimensional structures in a fluidic channel. The assay system comprises a channel, for example, a microfluidic channel, and a plurality of posts mounted to a support and arranged for insertion into the channel. The posts may be treated such that the posts are microporous, thereby greatly increasing the surface area of the posts. The posts are then treated with an agent that either activates the surface of the posts or facilitates immobilization of biomolecules of interest on the surface of the posts.
