POLYMERIC SUBSTRATE WITH A SURFACE HAVING REDUCED BIOMOLECULE ADHESION, AND THERMOPLASTIC ARTICLES OF SUCH SUBSTRATE

摘要

A substrate is described having a treated contact surface comprising a carbon or silicon compound comprising from 1 to 30 atomic percent oxygen, from 0.1 to 30 atomic percent nitrogen, or both, each as measured by XPS. The treated contact surface has a biomolecule recovery percentage greater than the biomolecule recovery percentage of the surface before treatment according to the method.
