Contrast in pollen grain and lead particles through foldscope

Name: Reya Gafar College Name: CMR National PU College ITPL, Bangalore Description: We had the opportunity to observe and differentiate various nano particles of everyday life that we brought as samples to our college. A great variety of shapes and sizes were observed through the foldscopes that day . This particular picture is of pollen…

Monosodium glutamate crystals

Monosodium glutamate (MSG) is responsible for the umami or “savoury” taste of many of our foods. I was able to buy a tiny amount at a bulk food store for only a few pennies….can’t recall the last time I bought something so interesting for only a few pennies!

Raw Honey – polarizing light clip

Raw Honey often contains pollen and tiny bits of beeswax. I think the structure at about 4 o’clock maybe wax, but am not sure if I can say so confidently. As you watch the clip under polarized light, you can see the sugar (primarily glucose and fructose) crystals shimmering. Ambient room temperature is quite high…

Methotrexate – short movie clip with polarizers

Here is a short clip of the Methotrexate crystals under polarizing filters.  Methotrexate was one of the first chemotherapeutic agents (and still used), and was discovered by Yellapragada Subbarao, who also had major contributions in elucidating the role of ATP and earliest antibiotics.

More Potash

Here is a short polarized film of potash which contains a number of potassium compounds. You can see the birefringent potassium nitrate crystals.

Potash

Here is Potash with polarized light and you can see the birefringent KNO3.

Egg White

Chicken egg is the best source of protein, lipids, vitamins, and minerals. Eggs consist of 3 main components: eggshell, egg white, and yolk. Albumen commonly known as egg white is rich in proteins. Albumen color is opalescent and doesn’t appear white until an egg is whipped or cooked. Egg whites are a low-calorie food containing…

I Sakshi Sangwikar along with my fellow student Gayatri Tulapulkar at CMR National PU College at ITPL, Bangalore observed salt under a foldscope on 8th June, 2018. Salt is a white transparent crystalline compound.  It is found in the rocks of mines. It is seldom used in our everyday life. Salt gives taste to our food. It…

Fibers from Nature -2 (Spider silk)

In the corner of my house, I spotted a web. Fixed it on a slide using a cellotape and viewed it through the Foldscope. I was astonished as it revealed the facts about it as a fiber material. The spotted spider web  A spiderweb commonly found in all house hold as a dreaded thing can…

Sticky pollen

I had always imagined pollen to have thick, spiny covering called exine, which had germ pores on it. I came across Morning glory plant with pink flowers. It had bell shaped flowers, with the stamens quite deep seated. I took out the anthers, which had some staminal hairs along the filaments.  I could see a…

Table sugar with polarizers

For this, I mixed regular table sugar with tap water and let it air dry.  Then observed this at the edge.

Fibers from Nature -1

I, Aman Arjel  of SD College, Chandigarh could never imagine, sample collection for foldscoping could lead me to a summer vacation project on fibers of biological origin. It all happened by chance. Thanks to my buddy Kanwar Pal Singh who noticed Calotropis fruit – a follicle (which our Botany teacher told) and chose to see…

Bubble wrap under microscope

I saw a bubble wrap under Foldscope and found this, Dont know the exact about the structure but there seem some small air sack like structure . with

Matchstick cells

The school year has begun, with new textbooks, new stuff to learn, and soon, new foldscopes for students in ten of the TSWREIS schools — thanks to DBT and Prakash Lab’s ‘India Foldscope Phase 1’. The school curriculum of Telangana State luckily prescribes quite a few microscope activities. We are trying these out, with a…

Polarized Explorations Part 3!! Copepods and Ciliates

Hello everyone! Thanks to iGEM I’ve had absolutely no time for foldscoping lately 🙁 but I’m determined to exploit this mini vacation in Ratngiri to its fullest 😀 Till now I’ve observed some pure chemicals and fruits in cross polars but this time I’ve tried doing something that I’ve been dying to try my hands…

Hyaluronic Acid dried on slide

I put a drop of a Hyaluronic acid solution on the slide.  I didn’t see anything with brightfield/polarizing microscopy.  I looked at it again 2 days after it had dried, with one polarizing filter, then both and finally with polarizing filters and a “frugal” compensator (the coverslide in our Foldscope kits).
