Integration of curli fibers with textiles via vacuum filtration. (a) A scheme of the vacuum filtration protocol adapted for textile–protein composite fabrication. (b) SEM images of textile–protein composites created using 0, 45, 60 and 90 mL of curli producing bacterial cultures. The protein content in the composites are 63 mg/cm2, 185 mg/cm2 and 500 mg/cm2 for 45, 60 and 90 mL of culture filtered, respectively. Scale bars: 300 µm. (c) Surface porosities of the different composites and acrylic control analyzed using ImageJ. Inset: Surface porosities of acrylic–curli composites only, excluding the acrylic control with high porosity.
