I have observed six different types of face masks being used in India during the COVID-19 pandemic under my Foldscope. Depending on the size of the spaces between the fibres of the masks, I’ve analysed the ability of each mask to protect the wearer, and those around the wearer. Blue Disposable Mask A regular, single-use…

Pre-Introduction / COVID pandemicIt’s time to question everything we do and change our systems.As we witnessed the need in this pandemic, how much people should have been more systematic and have been working in large scale groups. Moreover, the importance of enabling local communities to lead their ecosystem development because as many as large entities…
Fibers
Last week, we organized a teachers workshop which had a session on fibers. Teachers worked with a range of fibers to test them for various properties like combustion: There was also a part of the unit where they looked at fibers under a microscope. I thought would be nice to try with a Foldscope. So…
Fibers from Nature -5 (seed dispersal fibers)
The more we explore, the more fascinating things are revealed. The fibers seen in a weed could be so amazing and strongly woven is beyond imagination. Foldscopy of a weed with its seed entangled in a tuft of cottony fibres is wonderful. Probably the fibers aid in seed dispersal. The details of this exploration…

Experiments with Cross Polarization and Fibers
In the published papers, it’s clear that a variety of flavors of the Foldscope are being developed to allow for specialized lighting or contrast-enhancement. Some will require additional components, but one in particular seems accessible and easy to adapt the “vanilla” brightfield Foldscope. Polarized light microscopy is attainable by introducing two, perpendicularly oriented polarizing filters…
