a Filtering membranes made of recombinantly produced spider silk proteins. (i) Scheme of the spider silk non-woven mesh used as filter membrane. (ii) SEM image of an electrospun spider silk protein filter mat. (iii) The e-spun meshes were tested in air filtering applications, showing a higher filter efficiency than tested commercial filters. (iv) Filter mat production was scaled-up using centrifugal electrospinning together with a roll-to-roll process. Model showing the spinning device: scaffold support bracket (1), spinning chamber (2), collector (3) and winding unit (4).

(i) Scheme of the production and application of the composite meshes. (ii) SEM image of the particle-loaded e-spun fibers. (iii) degradation kinetics of pyraclostrobin upon photolysis.
