Re: [DIYbio] Re: interesting!

I've actually done a really crappy version of this with a UV lamp, plastic wrap around an open petri dish, smeared with sunscreen on half of it. Repeated this with a few different SPFs, works markedly.

Yeah - very nice work. I've been working on something similar at BioCurious as well. In fact, I put in a question to the "Ask a biosafety expert" a while back, on whether sterilizing with UV and then embedding in clear resin is sufficient to be able to hand out a bacteria-laden plate to the general public.

Reading some of the news articles about his work, it sounds like he's using "radiation" rather than UV light. Some of the stories seem quite explicit about making that distinction, but it wouldn't be the first time a reporter got a detail like this wrong. Maybe an Xray source, with a photo negative made from an etched copper clad board?

It looks like some kind of nutrient/growth promoter was plated down and the bactos grow on it, or there is antibiotic elsewhere.
