The innovation in the field of microscopy is experiencing an astounding surge. The latest development comes from researchers at Winona State University, Minnesota, who have designed a revolutionary device called the Glow Scope, a Fluorescence Microscope. It effectively leverages smartphone technology to project features of various microscopic organisms onto a large scale, featuring intricate details such as their brain, spinal cord, heart, and head and jaw bones.
Understanding Fluorescence Microscopy
Fluorescence Microscopy works on a unique principle. Traditionally, an optical microscope analyzes an object by observing how it absorbs, reflects, or scatters visible light. On the other hand, a fluorescent microscope takes this idea one step further by studying how an object re-emits the light that it has initially absorbed, in other words, how it fluoresces.
Under this mechanism, the object is radiated with light of a specific wavelength. The particles within this object, known as fluorophores, absorb this light and reemit it at a higher wavelength. To execute this task, the object is infused with these particles before being placed under the microscope.
The Working of a Glow Scope
Using a Glow Scope requires more than just access to the device. Potential users need to have available fluorophores, suitable biological samples, knowledge about combining the two, and some level of understanding of physics to determine which LED flashlight to buy for maximum utility.
Where the traditional Foldscope stood out was its simplicity and accessibility. Invented in 2014 by a group of scientists at Stanford University, Foldscope is a handheld microscope primarily made of paper. It can be assembled in just 30 minutes and is capable of capturing images of cells. However, Glow Scope’s ability to function as an efficient fluorescent microscope for a relatively small cost represents an unprecedented breakthrough.
Implications and Applications of Glowscope
The accessibility and affordability of Glowscope make it a promising tool in both research and education. Researchers can prepare samples and take them to schools, allowing students to observe these microscopic elements first-hand. This approach boosts the practical learning experience for students, furthering their understanding of complex biological concepts.
Despite the need for specific knowledge and resources to operate a Glow Scope, its introduction presents an invaluable opportunity for scientific exploration. As technology continues to evolve, tools like the Glow Scope will continue to bridge the gap between theoretical knowledge and practical application in the world of biology education.
