Key Points

  • A highly porous thin film developed as a biomaterial substrate
  • Thinner structure of films makes cell culture simpler than 3D porous scaffolds and enables better cell recovery for downstream analysis
  • Compatible with high-throughput screening systems


The University of Central Florida invention relates to the development of biomaterial substrates known as frozen films. The frozen films are highly porous thin films with micron-scale porosity and fibrous struts. The frozen films are expected to be compatible with high-throughput screening systems used by pharmaceutical companies and biotech companies for pre-clinical drug development applications.
