Laser Dye Jonthinobacterium lividum

Hi all
Just to know if there’s information about Jonthinobacterium Lividum is photosensitive to certain light spectrum? can laser effects its’ growing? this is what I found for the basic part:

I have been looking into this list of materials from the fabric-academy.
very well done!

let’s collect some ideas here on different bacterial dies, photosensitive bio-materials and sonogenetic opto-quantum tesla microboes.

i guess we talk to our good old friends at waag to get some stuff when we need.

Sounds like an incredible list! :dizzy::dizzy: Would love to add to it, but the link is not working…

edited the link above. was mistake in copy / paste

Found this publication on e.coli that was turned RGB light sensitive.

mbe we can just ask them to send some over. here is the original “behind-the-paywall” paper:

hei hei weiwei

nice to meat you, have a look at this project here and further notes on the wiki.
hopefully we can meet in taiwan.

Hello mamaya

Super cooool I’d love to participate with your project here or there, I also have great interests for those bacteria dyes, I’m curious if there are possibilities to grow it with light/laser etching influences participate!

best,

Wei

Looking into other “sunlight” sensitive dies made from Kaki aka Persimmon…

maybe can also be patterned with UV exposure instead of sunlight?

Hey Marc and Wei

yes I have read about this too, its pretty interesting. I would love to do some trials. They (the Japanese , haha, very general) use unripe fruits. And the persimon juice is also used for making paper water resistant. They also use it to make the Rice Shibori patterns. And I think it also needs to ferment in advance.

Are you in Geneva too? When are you next in Randen? I bet there will be some of our desired bacteria in our burried clothes, (or in the rest of them)

I would very much like to participate more! See you soon! Corinna

hey Corinna

Thanks for the reply, basically I am looking for dyes with photosensitive properties to UV, so I can “laser dye” those fabric in large scale. I now am using cyanotype and it works pretty well. I thought persimmon dye and bacteria dye might turns this toxic process completely nature.

Unfortunately I am based in Taipei, but will meet Marc soon hopefully in the near future.



not soooo unfortunate place to be :slight_smile:

Dear Wei marc showed me your work earlier - thats really cool. i was actually wondering two years ago of cyanotype would work with lazer, and we didnt have those strong lazers to try it. Is cyanotype salt toxic???

How long does the lazer need to point to the spot to print? What Is Taipeh like?
