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…
