Researchers from the Swedish SLU & Karolinska mass produce synthetic spider silk

Some time ago MPI Halle, Germany, produced super strong spider web by coating it with ALD (Mato Knez et al). At that time the research seemed like a peculiar thing. Now however, Swedish researchers from SLU and Karoliska can mass produce synthetic spider silk at high rate and in large quantities. So all you have to do now is to integrate an ALD reactor into the machine below ...
