🚀 Kickstart 2025 – We present: BioPoly!
As part of our early-stage funding program KICKSTART, the Hof University team "BioPoly" is exploring the potential of recycled, biodegradable polyester yarns. 🧵🌱
The goal: develop a prototype within 6 months that could lead to a sustainable start-up in the textile sector.

I am excited to share our newest publication on #agarose. First authored by my colleague at @unijena, I am happy to have contributed to this work: we present novel functional agarose gels unsing "advanced #polysaccharide #chemistry" and their characterization.
Eine biobasierte Alternative aus #Chitosan kann PFAS ersetzen.
🕵️ Diese Woche berichten zwei der Forscher, Achim Weber und Thomas Hahn, im Blog #Biointelligenz über ihre Fortschritte.
🙌Neben weiteren Expertinnen und Experten kommen die beiden Forscher auch im Fraunhofer-Magazin 4/2023 zu Wort.

Ich habe ein interessantes Jobangebot für #Neuseeland bekommen. Ein #Kunststoff|hersteller sucht Ersatz für zwei Herren die kommendes Jahr in Ruhestand gehen werden. Die Aufgabe wird sein den Kunden dieser Firma bei der Verarbeitung der #Biopolymer|e zu helfen. Also wieder Reisen, aber nicht mehr so viel und lang wie jetzt. Abgedeckt werden sollen #Neuseeland und #Australien. Wie viele Stellen das werden ist noch nicht klar, das wird aber großen Einfluss auf meine Entscheidung haben.
@kingu true, true...
The #Cannabis #prohibition was solely orchestrated in the #USA to protect #wood farmers and sawmiller's interests.
People like #RandolphHearst that had significant stakes in that industry.
Because #hemp is the better #fiber source for #paper just because one doesn't have to deal with a shitton of oily sludge known as #Lignin, which is basically a #biopolymer that makes wood #flexible yet strong...

It’s Printable, It’s Programmable, It’s E. coli
Well, whaddya know? It seems that E. coli, the bane of Romaine and spinach everywhere, has at least one practical use. Researchers at Harvard have created a kind of 3D-printable ink that is alive and made entirely of microbes produced by E. coli. Although this is not the first so-called living ink, it does hold the title of the first living ink that doesn't need any additional polymers to provide structure.

Because the ink is alive, it is technically programmable in the sense that it can self-assemble proteins into nanofibers, and further assemble those into nanofiber networks that comprise hydrogels.
One of the researchers compared the ink to a seed, which has everything it needs to eventually grow into a glorious tree. In this way, the ink could be used as a renewable building material both on Earth and in space. Though the ink does not continue to grow after being printed, the resulting structure would be a living system that could theoretically heal itself.
The ink creation process begins when the researchers induce genetically-engineered bacteria cultures to grow the ink, which is also made of living cells. The ink is then harvested and becomes gelatin-like, holding its shape well enough to go through a 3D printer. It even passes the bridging test, supporting its own weight between pillars placed up to 16 mm apart. (We'd like to see a Benchie.)
Microbial Mechanics
Is it weird to work with microbes? Not really. They are already a part of vitamins and some perfumes, and other types of microbes are out there maturing into biodegradable plastics. E. coli has been used before to create a hydrogel capable of growing and regeneration, but it wasn't viscous enough to pass through a printer. So they genetically engineered the E. coli to produce a natural polymer from fibrin, which is a blood-clotting polymer possessed by humans and animals alike. The polymer created by the bacteria is designed to link together into a network, which one researcher likened to a heavy-duty cargo net.
This all-microbe E. ink is still being developed. So far, it is already quite an improvement over what was viable only five years ago. Why 3D prints with E. coli? The ink showed promise as a drug delivery system, for example. In a test, the ink was shown to release an anti-cancer drug called azurin after being exposed to a certain chemical. One of those functions might be cleaning up the environment. In another test, the ink was proven to sequester the toxin BPA from its surroundings.
Though this all sounds great, the ink is still in development and has a way to go. For one thing, it doesn't withstand drying out, but that may not be an obstacle if the ink is combined with tissue engineering. However, if we're going to use it as a self-regenerating material for building habitats on Earth and in space, it will have to become more stable.
