Need to detect pathogen levels in a 240 cu ft room after it has been subjected to dry fogging usi...
Public Lab is an open community which collaboratively develops accessible, open source, Do-It-Yourself technologies for investigating local environmental health and justice issues.
Dry fog technology utilizes a chemical disinfection process: the system vaporizes the sporicidal chemical, producing very fine droplets of disinfectant which are dispersed throughout a room, without any manual efforts. ... The dry fog solution is evenly and completely dispersed in the room or rooms. We need to be able to determine that the CFU (n microbiology, a colony-forming unit (CFU, cfu, Cfu) is a unit used to estimate the number of viable bacteria or fungal cells in a sample. Viable is defined as the ability to multiply via binary fission under the controlled conditions. ... Expressing results as colony-forming units reflects this uncertainty.) has been reduced to predetermined level of either 3-Log or 6-Log reduction i.e. 99.9% of 99.9999%
The basis microscope kit and LED light are interesting but I would also need software which could automatically analyse the results as we cannot have any human intervention
Hi, can you fill us in a bit more on details of your interest and situation? What kinds of pathogens, and what is dry fogging? Sounds interesting!

Ah, ok -- do you have example images of the kinds of data you'd need to collect, and a pixel/micron resolution you're aiming for?
Also, what kind of fluorescent light would you need?

I'm thinking of whether the Basic Microscope Kit could be helpful:
http://publiclab.org/basic-microscope
and also something like this LED light: https://publiclab.org/notes/warren/03-10-2016/honlian-60s-led-nail-polish-hardener-various-led-fluorescence-updates

Interesting! Do you have an example to refer to in how an automatic analysis could work?

Sorry no I don't have an example.
