The fun part here is that, technically, once they get a 'good enough' product and workflow up and running, adding/changing/incorporating biological properties is (mostly) just a DNA-based bit-flip away. We at Serotiny are already collecting protein domains from organisms with various capabilities - including water solubility, hydrophobicity, enzymatic capabilities, covalent attachment sites (for dyes), light-activated properties/crosslinking/dissociation/etc. And all of those protein domains we're collecting should be 100% compatible (+/- a fair bit of a tooling-exercise) with both Bolt's leather and their silk. So it should get fun once they have a solid and stable 'platform' up and running. They will be able to incorporate most any property from nature with an existing proof of principal, not just any property form mammalian hides. Congratulations guys!
