Flower Petal: Bio60_2019

This is a photo of a flower petal. Grooves or canals are visible in the picture, but I’m not sure what they are for. I can also see small circular shapes, which I am inclined to identify as individual plant cells.

TEA Bio60_2019

Since I had more than enough to spare, I decided to look at powdered tea for my second Foldscope post. To prepare the slide, I added the tea to my slide and added a drop of water. I then tried to take clear pictures but many ended up blurry. When I looked, I saw what…

Squamous Epithelial Cell (Bio 60)

The other night, I asked a good friend if she wanted to go help me look for something outside to examine with the foldscope. But, dreading the blistering cold of the recent nights, we first decided to see if we could find anything interesting indoors, and our search resulted in one my favorite images I…

Ant Bio60_2019

My dorm community has founds numerous, small, brown ants in our lounge. I decided to look at one of them using my Foldscope. I examend the head, eyes, antenna, legs, thorax, and abdomen. I will attach a photo of the head and thorax of my ant specimen. I was especially fascinated at the joints of...

Kleenex Tissue Bio60_2019

I was thinking about what things are semitransparent that might look cool under a microscope. Sitting at my desk I remembered that tissues are made up of 2 sheets of cloth, hence 2 ply, and that 1 sheet is thin enough to view with a foldscope. So, I tore the a clean tissue in order…

Orange Pith

Have you been told before to eat the white, spongey part of an orange between the fruit and the peel because that’s where all of the nutrients are? While eating my orange one afternoon, I decided to look at the orange pith using my Foldscope. According to Dr. Weil, the pith is high in fiber…

Pollen; Bio60_2019

I decided to take a look at the pollen of a flower that I found in my dorm’s flowerbed. Having religiously avoided pollen growing up due to an allergy to Cedar when I was younger, I was curious to see what had had me so watery-eyed in the winters in Austin. While my camera’s refusal…

Worm Bio60_2019

This is a photograph of a worm I looked at using my foldscope. The worm was collected by Steph from the top of the mud the teachers brought into class. The worm was alive and moving, so it was difficult to focus and ensure it was captured in the frame. Nevertheless, I am curious about…

Mouse Spleen Sections – Bio60_2019

Firstly, the credit of cutting these mouse spleen sections belongs to Nolan, a research assistant from the lab I work in, who kindly donated these sections for my assignment. The sections were originally submerged in liquid in a well plate to be used for immunofluorescence staining. Using a paint brush, I lifted each section out…

Orange Peel – Bio60_2019

I was eating an orange before class on Thursday, so decided to look at a bit of orange peel using my foldscope. You can really see the texture of the peel under the lens, with different layers and different thicknesses of the peel in different places. As I was trying to focus the image, it…

[Bio60_2019]Ant Head and Abdomen

I was curious to know if I could use the foldscope to learn something about how ants were, so I decided to look at them in more detail. I used a piece of tape to grab an ant that was on some plants that had been collected, and then used tweezers and scissors to break…

Bio60_2019 – Blueberry Skin

Since I looked at plants for my last Foldscope post, I decided to look at the skin of various fruits for my second post. I took a strawberry, blueberries, and honeydew from my dining hall, but I am focusing on the blueberries because they had the most clear and interesting results. To prepare the slide,…

In this sample, many plant microbes were visualized. The sample in the picture was prepared by using a normal glass slide with a cover slip. In order to prevent the sample…

Millipede Cuticle under Ultraviolet Light

I found this flat-backed millipede (order Polydesmida) specimen while walking around the Stanford campus at night after a strong winter shower. I removed a small piece of the exoskeleton cuticle, and examined it with my foldscope while shining an ultraviolet light, which produced the iridescent blue seen in the iPhone image. β-carboline has been identified…

Human Skin: Bio60_2019

After a workout involving ropes, my hands were blistered. After a few days, the blisters stopped hurting, and the dead skin started to come off; there was skin already forming underneath it. I decided to look at the clear tissue under the foldscope. In one of the photos, remarkably, there are distinguishable “dots” composing the…

Spot on tangerine skin: Bio60_2019

When picking tangerines on the Stanford campus I noticed That some of the fruits had a few little black spots on their skin. I wondered what these spots were and decided to look at them with my foldscope. I picked and saved a tangerine with a spot until I had time to prepare a slide…

Strand of Hair Bio60_2019

This is a photograph of a hair sample collected from my own head and examined with the foldscope. The image focuses on the root of the hair, which contains the hair bulb. According to my research, the hair bulb is where living cells divide and grow to build the hair shaft. I tried to look…

Colorful Leaves in Winter

On my way back from the dining hall on campus, I noticed a bush with leaves of four different colors. I was curious as to how they might look different on a cellular level. These leaves were sampled in February. As the length of day and amount of sunlight changes, chlorophyll can break down, causing…

Flower Petal

While walking to class, the bright red flowers caught my eye. I decided to bring them to class and observe them under the microscope. The thin flower petals were transparent, but I thought preparing them with water would lead to a better visual image. It did. In great detail, I was able to see a…

Tooth Plaque – BIO60_2019

Here is a photo of the plaque found on my teeth. Before brushing and flossing my teeth at night, I took a small sample of plaque. This plaque came from my upper central incisors. I smeared a thin film of the plaque on a glass slide and placed it inside of my flodscope. I was…

[Bio60_2019] – Moss

Thanks to the winter rains the past few days/a few weeks ago, we’re finally getting lush greenery around campus. So I decided to collect some moss growing near Lake Lag to examine with my foldscope. The moss didn’t require too much preparation, since it is pretty thin/translucent even when intact. I took a small bit…

Skeletal Muscle – BIO60_2019

After observing a few samples from rose petals to mud from the Badlands Nature preserve, I though the skeletal muscle sample given in the kit was most vibrant. I have always been interested in anatomy, and though it is unclear where exactly the muscle was extracted from, the color and properties of the sample stuck…

[Bio60_2019] Colombian Raisins

When I came to the U.S., I decided to bring some snacks with me from back home. When I got the foldscope, I decided to look at some raisins I had brought with more detail to see if I could lean anything interesting. To observe the raisin, I used tweezers to break the raisin apart,…

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…

Bio60_2019 – Green Leaf

These photos were taken of a leaf I found outside of my dorm on February 6th. To look at the leaf with the Foldscope, I actually prepared two different slides, one with water and one without. I took sections of the leaf from the bottom-most portion, since I figured these cells would be the youngest….
