The beauty of Fluorescence Microscopy Fluorescence microscopy is highly sensitive, specific, reliable and extensively used by scientists to observe the localization of molecules within cells, and of cells within tissues. A fluorescence microscope works by combining the magnifying properties of the light microscope with fluorescence emitting properties of compounds. Fluorescence microscopy uses a high-intensity light source that excites a fluorescent molecule called a fluorophore in the sample observed. Principle. The specimen is illuminated with light of a specific wavelength (or wavelengths) which is absorbed by the fluorophores, causing them to emit light of longer wavelengths (i.e., of a different color than the absorbed light). One limitation of fluorescence microscopy is that fluorophores lose their capacity to fluoresce when illumi- nated due to photobleaching. Also, although use of fluorescent reporter proteins enables analysis of living cells, cells are prone to phototoxicity, especially when a short wavelength is used. Follow @sciducate to learn daily

Tears under microscope 🔬😶 Amazing video by: @tardibabe 🤗 You can see as her tear dries up, a beautiful frozen landscape is created a remember how salty tears are? When water evaporates, salt crystals are formed! Not only do we shed tears when experiencing emotions, but tears are also released every time we blink. While emotional tears indicate distress between individuals from certain animal species, they serve additional functions beyond emotional expression! Tears consist mainly of water, providing hydration to the eye, aiding in clear vision by focusing light, and facilitating the dispersion of electrolytes, proteins, lipids, and mucins. Electrolytes, such as sodium, chloride, calcium and potassium are important for maintaining pH stability and normal osmotic pressure (they also create beautiful crystalline patterns on the microscope slide when water evaporates). Lots of different proteins are present: some are antimicrobial, some are enzymes that help breakdown lipids and other proteins and some are involved in wound healing and inflammation regulation. Lipids can also be found in tears! Can you see some small oily droplets floating around? These lipids include cholesterol, triglycerides, and phospholipids, and they prevent water to evaporate too quickly. The last components are mucins, large glycoproteins that help spread tears evenly over the ocular surface. All of these elements aren’t just randomly sitting in water. In fact, they’re all organized in three layers. The outer layer is the one that contains lipids and keeps tears from drying up. The middle layer is the watery one which keep the eye wet and nourishes the eye tissues. The inner layer is made of mucus and helps the thin tear film stick to the eye. Tears also form a barrier against foreign particles like dust or dirt and protect your eyes from pathogens like evil bacteria or viruses. There are even white blood cells secreting antibodies in your tears! These guys are always at work for you, how sweet 🥰

Why do scientists make cells glow? Normally, cells are colorless under a microscope. we can’t see most of their internal structures or specific proteins with the naked eye. To visualize them, we often engineer cells to express fluorescent proteins - molecules that emit light when excited with specific wavelengths. This allows us to distinguish and track different cell populations under a fluorescence microscope. By labeling cells with fluorescent proteins such as mCherry, we can follow where cells go, how they interact, and how they change over time. To study specific proteins or organelles, we have two main approaches: 1. Fluorescent protein tagging - genetically fusing a fluorescent protein to a protein of interest so it glows naturally inside the cell. 2. Fluorophore-conjugated antibodies - using antibodies that bind to specific proteins and carry a fluorescent dye, allowing precise visualization. This is especially powerful in immunology and cancer research. We can label immune cells and cancer cells with different fluorescent markers, making it possible to watch how immune cells recognize, attack, or sometimes fail to eliminate tumors. Fluorescent labeling also helps study tumor growth, immune cell infiltration, and cell-to-cell interactions inside tissues or experimental models. What looks like colorful cells is actually a powerful tool that helps us understand the immune system and develop better strategies to fight diseases like cancer. #scientist #science #laboratory #immunology #microscope

Wait till the end 🧪🩷💜🩵💙 We definitely need to do a collaboration with @luminescent_chemist 👩🏼‍🔬🧑🏻‍🔬 Anthracene (C₁₄H₁₀) is an aromatic molecule whose π electrons absorb UV light (~365 nm), jump to an excited state, then release that energy as blue fluorescence. The blue color simply matches the energy gap between excitation and emission. Three optical setups reveal different information: • UV → fluorescence • Polarization → crystal orientation (interference) • λ plate → wavelength variation #crystals #chemistry #science #art #fluorescence #UVlight #microscopy #crystalart #scienceart #chemistryart #bluecrystal #chemist #artist #experiment #notAI #Helnium #fyp #virałreels #scienceexperiments #artandscience

I missed my opportunity to post this bleeding algae on Halloween (it’s unfortunately not actually bleeding)! I found some interesting dark globs of Cyanobacteria growing on the air tube in my stock tank. These globs were shiny and nearly black…until you crushed them. Then they released a deep red pigment. There wasn’t much living inside those mats, but the life on and around them kept me busy: Lacrymaria, Stentor, Dileptus, a few flagellates I didn’t bother trying to identify because I know my limits, some Euglenoids, and a rotifer from the family Notommatidae. It’s one of those samples that reminds me why I love microscopy. 🔬 Olympus BX51 w/ DIC from @mundaymicroscope 🎥 iPhone 14

These two are just single-celled organisms; basically a bunch of building blocks and cell machinery wrapped in a membrane, and here you can see what happens when that membrane bursts and spills its contents out. . The smaller organism, Holophrya, has harpoon-like structures around its cell mouth that are expelled to immobilize prey. They usually go after smaller microorganisms or decomposing organic matter, so this whole scene was so unexpected my jaw was on the floor. . When I found these two, Holophrya’s little harpoons had already fired and pierced the cell membrane of the larger organism, a Stentor, and it was tugging on the Stentor’s membrane. After a few seconds, the membrane popped almost like a balloon, and the Stentor’s cell contents spilled into the environment for Holophrya to feed on. . Holophrya has sensory mechanisms that let it detect the chemical signals coming from the spilled contents of the Stentor. So it kept swimming around for minutes, swallowing all the soup-like cytoplasm droplets and solid chunks of organelles, and even the bits of lunch Stentor had earlier. . While Holophrya was feeding on its spilled “guts,” the Stentor was busy repairing the hole in its membrane. Although it lost a lot of cell mass, Stentor has the ability to recover from all this and regenerate its deformed cell back to normal like nothing has happened. I wish I had that skill of regenerating emotionally, I’m like a savant of sad memories and broken cell membranes. 😂 . Thank you for reading! I’ll share a three-minute clip of this on my exclusive pages so you can watch the Holophrya keep feeding on the bits while the Stentor continues to repair itself. Your support makes it possible for me to keep posting, and I appreciate it. . Best, James Weiss

Your favorite microscope bro 🫥 has upgraded his camera game 😆. I hope to bring y'all better, more interesting videos and maybe you'll notice the difference in today's post. Anyways, this time we're looking at an algae called Volvox. 🔬 I've been wanting to do a video on Volvox for a while, but finally have the equipment to do it justice. Volvox are actually colonies of hundreds to thousands of smaller cells that work together to do lots of things. Some are moving the colony towards a light source for photosynthesis, some are making the food, and others are reproducing. You can find them in places like freshwater ponds that get plenty of sunlight. They are super fragile and need steady conditions to thrive. Please let me know if you enjoyed this style of filming as I'm always looking for ways to improve! And if you're new here, I post videos of microorganisms, crystals, and other interesting substances under a microscope. Give this page a follow to see more. 😆 Best, Alex
