The Genomic Integrity team has been looking into the best ways to get the cheek cell assays to be really DIYbio (for DIT research!) and has been testing open-source microscopy and imaging methods at Hackuarium:
Inspiration
Many DIY microscopes exist already. This page from Hackteria describes a few options out there, even using old webcam lenses, upside down...
We had great fun playing with variations on the theme, even simple lenses embedded in simple materials (like cork) during the BioFab Convergence...
(to add pic)
The first Foldscope was developed at Stanford, by the group of Manu Prakash, and was published in PLOSOne.
First Foldscope Tests at Hackuarium
The first attempts to make Foldscopes at Hackuarium relied on vector graphic files found on the internet in Oliver Bosewell's blog, and included in the folder linked below (under Further information).
We used the laser-cutter in the maker space (Made@UC Thanks, Marc!) to cut the pattern, and simple glass beads for lenses (thanks, Sachiko!) and made our first tests on 5May17.
An image of one of our first folded scopes and an image of an old histology slide can also be found in the folder linked below (under Further information). Even though the beads were 'up-cycled' from microbiology experiments (even scratched), the results seemed promising enough that low magnification (140X) borosilicate glass lenses were ordered.
The second build and an image with cheek cells stained with methylene blue is also included in the folder linked below.
Steiner School Student visit
We look forward to welcoming 18 students from the Steiner School (15-18 year old) on 22May2017, with their teacher, Veronica Monticone.
We have 20 packets with purple, Hackuarium -embossed pieces for the Foldscope (3 main ones), including a proper 140x lens, ready for the arrival of 18 students at 9am... :)
Watch this space for more soon!
Hopes to use fluorescence modules for the cheek cell assays.
With a blue LED, a diffuser, and a filter, fluorescence may be possible, which will be especially important for the cheek cell comet assays, if no colored alternative to SYBR-Safe is found.
