Observed Euchlanis Rotifer under Foldscope

Euchlanis is a genus of the microscopic invertebrates known as rotifers. Sometimes alternatively referred to as wheel-animalcules, rotifers feature a characteristic circular arrangement of cilia at their front ends that are reminiscent of a turning wheel when they are in motion. In addition to a ciliated corona, or head, Euchlanis species have transparent bodies and two strong toes…

Feather of Peacock

We observed the feather of peacock under foldscope and learned about the cells of rachis. The feather consist of  Vane, Rachis, Barbs and Hollow shafts. The rachis contains pith, which is composed of air-filled keratinised epithelial cells surrounded by a solid keratinised outer cortex. … Barbs: The series of branches fused to the rachis, constituting the major surface area of…

Posterior Spiracle of Maggots ( Musca domestica Larvae)

Here’s a beautiful and detailed picture of the processed Posterior Spiracle of the Musca domestica Larvae, which was collected from an infected wound. The larvae was boiled in 10% NaOH for about 5 mins and was thoroughly rinsed in water. It was then dehydrated for 2 – 5 mins in increasing concentrations of alcohol ( 70%,…

No High Mag Lens in Deluxe Kit? Would Love to Buy One!

I just received my Foldscope Deluxe Kit a few days ago and I have not put it down! I assembled the Foldscope according to the instructions and it works great. I believe the two lenses that came with the kit are the 140x magnification lenses, which leads me to wonder where I can find a…

Blood Smear under the Foldscope

  This past summer, together with the industrious Yash Jawale (BS-MS 2013) at IISER Pune, we began assembling the Foldscope. The high-mag and low-mag lenses were our two options that we were playing around with. Having the first device was super-exciting. However getting a reasonable image took some learning. Frame-grabs from the videos are what…

Hibiscus pollen grain

I saw a post earlier about pollen grains on the microcosmos. Was curious so I took out my high magnification foldscope and took a look and the hibiscus pollen grains from my garden.

Pollen from Hibiscus flower

Pollen grains from an unknown Hibiscus sp. The grains were collected by gently dabbing a tape slide against the anthers. Also included are some photos of the flower and plant the pollen was collected from.

Study in Light: Low/High Magnification, Onion Skin and Natural Light.

  The topography of the onion skin delights me and the colors are so beautiful, including a purple impossible to capture. Under lower light, the cell walls look taller than the cytoplasm, and look to be ragged, not as I expected.  The shapes of the cells are interesting, and some are curved, perhaps bulging from…

Cells of a “schefflera” leaf – first foldscope use

                  Because of the pretty shitty weather I made my first attempt with the foldscope with an indoor plant. And I have to say that I’m very impressed! Amazing what this small paper thingy is capable of 🙂   First I tried it just with sunlight and…

Minerals with Cross-Polarized Light

Using some minerals samples that we had lying around at work and low budget tools (my fingernail to scrape off pieces of the minerals), I looked at crystal structures with a cross-polarized light Foldscope (see this post for instructions). First, some muscovite mica which forms in very thin sheets and has high birefringence (which is what…

In what patterns can a strand of hair go grey? Low/high mag pics

  After struggling to record high mag lens work, I decided that I might be simply misunderstanding what I see through the high mag lens.  Color saturation, light, and pattern are hard to interpret when we are used to our eyes alone or a low mag lens.  Reminds me of the concept someone else shared,…

Pollen – A first attempt at using FoldScope

  It was very difficult to juggle cameraphone + FoldScope + flexing + toushscreen shutter release, so the above is a crop from the very edge of the field of view. I dusted some pollen onto the included adhesive coverslips, which actually work really well as long as you methodically squeeze out the air to…
