No fume hood or any of the sort would be needed, at least not until the
vacuum deposition system is built and functioning. Chemical etching is
not what I have in mind.
The project of building the vacuum system takes a lot of good building
skills. We are dealing with high voltage, cooling systems, vacuums, turbo,
cryo, etc. and also machining parts and install sensors and other
electrical gadgets, motors, rotors, detectors, etc.
I wonder if Sudo (?) group would be inclined to collaborate in this kind of
As for the bio aspect, we would use the same protein expression methods you
at CCL are already using.

Sounds like a fun project! One possible limitation might be that we don't
have a chemical fume hood at CCL - only an internally vented, HEPA filtered
biosafety cabinet. We're not opposed to getting a fume hood, but it would
be up to you to figure out all the regulatory requirements, including
effect on building codes, issues around venting chemicals in a residential
If you don't need a chemical hood for what you have in mind, that
simplifies things significantly. If you just want to recruit a larger group
of people interesting in working on this, I would recommend that you and
your friends organize an informal talk or brainstorming session on the
topic. We'll put it on our Meetup, and we'll see how many people are

I am requesting your input on this idea since I have no experience
working in a collective way.
I want to build a Magnetron Sputtering Vacuum Deposition System to
produce thin films, ultra thin films, and nanoparticles.
I am interested in working at the interface of materials science and
My particular interest is exploring nano-materials for enhanced raman
spectra signaling - including bio-engineering for enhanced fluorescence-emf
However, other subjects also interest me, such as the toxic effects of
micro and nano-materials and how these materials interact with organisms,
cells and biological processes in general.
Building a thin film deposition system is a challenge but can be
This kind of equipment is very costly and only some very lucky people
have access to learning how they are built and how they operate.
This is because the magnetron sputtering chambers are used in the private
industry only by trained and skilled personnel. In universities and
technical colleges, only experts and selected talented students get access
to these machines while working on their thesis projects.
In YouTube I have watched people building their own vacuum chambers,
rather crude, o.k. for hobby but not likely to work for producing
nano-materials with real-life applications (sorry for being so critical).
I am contemplating working on building a system using your Collective
However, I have never worked in an open group setting and I wonder if
this would be a realistic expectation and if there would be any interest at
Although I am not alone. There are five of us in my group, we are people
with similar interests living and working in Berkeley with limited free
time to work on our own projects, since we have day jobs at UCB.
Only one of us has actually built such equipment before. The rest in our
group only have used the equipment and/or has worked on experiments using
nano-materials, mainly plants.
I look forward to your input.
