Seeking help on making sample slides

Hey guys, just needed some help. I have my foldscope with me but am so far I have been unsuccessful in viewing magnified samples. I have tried hair strand, tulsi leaf, onion peel, but to no avail. Please share some guidance on how to make perfect sample slide and other relevant tips w.r.t. viewing sample…

A Hair-y Situation

Growing up in America as an Asian-American, I have always been dissatisfied with my hair. Inundated by media which featured beautiful Caucasian women and seeing the silky, bright color of my classmates, I often found myself frowning at the dark, coarse, Asian hair of my ancestors. As a result, for the past 8 years of…

Dead Skin Two Ways bio60_2019

The beard hair follicle was pulled from a man’s beard using tweezers because it was oddly longer and lighter in color than the rest of his beard hairs. It was slightly curled. Using a pipette, a few drops of water were put onto it and a coverslip was taped on top of the glass slide….

Hair follicle

The hair follicle is a dynamic organ found in mammalian skin. It resides in the dermal layer of the skin and is made up of 20 different cell types, each with distinct functions. The hair follicle regulates hair growth.

Ant on a wire (hair) 

I love tools. The right tool for the right job makes all the difference. But sometimes you have to invent tools. And that’s so much fun; since if it does not work well – you can blame yourself and start all over again.  Here I share a simple method to mount small insects (say an…

Dyed Hair Effects

Purpose: To tell the difference between dyed and non-dyed hair. To learn the effects of dyed hair.  Problem: Could dyed hair end up being damaged? Hypothesis: If two types of hair are compared in the Foldscope then we will tell if dyed hair ends up damaged. Procedure: Analyze the two types of hair in the…

A close of up coiled-texture hair- uabbiotech_PVD

  Many people are intrigued by just how different the hair of African and African descendants is. There are numerous misconceptions about African-textured hair, chief among them that “black hair doesn’t grow.” This misconception stems from the biology of the hair structure itself, which is different from the structures commonly seen among other ethnic groups. This hair…

Senior Show – Progress! Drawings

Hello there, Foldscope community! I have returned to post in-progress images of my drawings for my senior show. I am also going to attach my blog post to this post because many of you have been wondering about my rationale for choosing such a “random” and “photographic” subject to draw. http://rocklandantiglitter.blogspot.com/2015/03/foldscopes-and-403-round-1-of-images.html?spref=fb I welcome any feedback…

Polar Bear Hair (with polarization)

I was very excited to come across this post on modifying the foldscope with polarizing filters: https://microcosmos.foldscope.com/2015/02/05/experiments-with-cross-polarization-and-fibers/ Since I work in a science centre, there is plenty of polarizing material hanging around but I decided that the easiest thing to do was to punch the lenses out of some old 3D glasses. Then I placed…

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,…

Found around the office

I received the Foldscope kit and after putting it together, I immediately looked around the office for things to view. The first sample I tried was a crusty piece of dead skin from my co-worker’s healing finger injury. (Yes, we tend to be gross around here) Well that was fun, but I wanted more. I…

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…

Hair Sample

These are my first specimens on the Foldscope. The first two are from a strand of golden colored dog hair. The next two are from a strand of human hair, naturally black recently dyed red. You can see there’s a clear coating on the dog hair. I do not know why as I have no…
