We developed a novel solid-state cell-free protein synthesis (CFPS) system using porous parylene. This material enables stable, on-demand protein production and programmable biosensing for portable diagnostic devices.

Area of Science:

  • Biotechnology
  • Materials Science
  • Synthetic Biology

Background:

  • Cell-free protein synthesis (CFPS) offers advantages for biosensing but requires integration into portable formats.
  • Existing 2D CFPS platforms lack the stability and spatial control needed for practical point-of-care (POC) applications.
  • Embedding CFPS machinery in 3D matrices that maintain activity is a key challenge.

Purpose of the Study:

  • To develop a stable, solid-state CFPS system for POC applications.
  • To demonstrate the potential of this system for programmable biosensing and on-demand protein production.

Main Methods:

  • Fabrication of a parylene-based scaffold using ice-templated chemical vapor deposition (CVD).
  • Loading the scaffold with CFPS machinery to create the CFPS in porous parylene (CinPP) system.
