Solution Overview

Problem

Current methods for producing collagen-coated surfaces for cell culture are costly and not suitable for large-scale manufacturing, particularly in human therapeutic applications, due to the high cost of animal-derived collagen and peptide sequences that mimic collagen.

Innovation Solution

The development of animal-free, synthetic, chemically defined surfaces using plasma polymerization of prolinol or proline to create a surface that mimics collagen-coated surfaces, allowing for human hepatocyte attachment without additional extracellular matrix proteins, utilizing plasma polymerization or chemical vapor deposition techniques.
