College name : CMR National PU College ITPL Bangalore Students : I PU Item viewed : Rheo leaf section Description: Students of I PU studied the structure of stomata from Rheo leaf and phenomenon of plasmolysis under foldscope today. A temporary slide with Rheo leaf section was observed under foldscope. Stomata with bean shaped guard…
Today one of my student collect Some spider web and watch through foldscope….
皆さんこんばんは！ 今日はウェビナーの参加者の皆さんと一緒にフォールドスコープでおもいおもいのサンプルを観察しました。 私は結晶の形を観察してみたかったので、食用塩を2種類用意しました。 フランスのゲラント塩 イタリアのシチリア産塩 サンプルは、紙のスライドとテープで用意しました。 撮影はiPhone6です。 写真は何も加工していません。デジタルズームも使っていません。 —-
Croton plants of this genus were described and introduced to Europeans by Georg Eberhard Rumphius. The common names for this genus are rushfoil and croton, but the latter also refers to Codiaeum variegatum. The generic name comes from the Greek κρότος (krótos), which means “tick” and refers to the shape of the seeds of certain…

For a few pennies, I was able to get some Epsom salts. I added water and let it dry on the slide and then viewed with polarizing filters. Magnesium sulfate is used medically for certain cardiac rhythm problems (Torsades des points), severe asthma, and in certain cases to protect baby when mother enters labor early….
Magnesium sulfate is used medically for certain cardiac rhythm problems (Torsades des points), severe asthma, and in certain cases to protect baby when mother enters labor early. It is also called Epsom salts and used for soaking and skin healing.
For a few pennies, I was able to get some Magnesium sulphate. I mixed in water and allowed it to dry on the slide. I thought it had dried, but when I looked at the clip I realized there was a drop of water (at about 7 seconds into the clip) at the top of…
College – CMR National PU college Name – Bhumika C Item – Ferric Chloride Description – Ferric chloride is deliquiscent. Viewed under the foldscope we could observe it melting and see the patterns emerging. It seemed like an eye and that fascinated all of us in the lab.
Observed a commercial sample of milk at GGDSD COLLEGE, Chandigarh with varied fat content of 6%,4.5% and 1.5%.Variations in the aggregation of fat droplets was observed such that milk with highest fat content i. e 6% showed highest degree of aggregation of fat droplets followed by milk with fat content of 4.5% and least degree…
With Foldscope instrument it is amazing to observe the particles which are hidden from naked eye.
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 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…
Here you can see the crystalline structure of sugars better.
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.
The first image shows crystals of methotrexate under plane polarized light. The vial containing them was to be discarded as it had expired 9 months prior. The second image is the same image with slightly higher magnification and under plane polarized light.
One day hands-on foldscope workshop training at Genius academy (juniors college)organized by Lakhimpur Girls college.
Here is a short polarized film of potash which contains a number of potassium compounds. You can see the birefringent potassium nitrate crystals.
Here is Potash with polarized light and you can see the birefringent KNO3.
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…
