Bottom-Up Instructive Quality Control in the Biofabrication of Smart Protein Materials

Abstract

The impact of cell factory quality control on material properties is a neglected but critical issue in the fabrication of protein biomaterials, which are unique in merging structure and function. The molecular chaperoning of protein conformational status is revealed here as a potent molecular instructor of the macroscopic properties of self-assembling, cell-targeted protein nanoparticles, including biodistribution upon in vivo administration.

Keywords: biodistribution; biofabrication; cell quality control; nanoparticles; protein materials.
