Cell Observation Using Inverted Fluorescence Microscope
Cell observation using inverted fluorescence microscope is now becoming a trend in medical diagnostics. Do you know that by now little by little simple and traditional microscopes are not anymore being used in hospitals and in diagnosis?
Physicians are now embracing and welcoming the innovation of a microscope which elongates wavelength so that specimen will be seen clearer.
What is a Fluorescence Microscope?
Are you familiar with microscopes? Perhaps you know that through the light source you are able to see the images in the eyepiece, but do you know that nowadays a different light microscope is being used to further reflect images in an intricate manner?
A fluorescence microscope is actually just like your regular standard light microscope but with added components and features that are integral in broadening its capabilities. If your traditional microscope uses light to illuminate the specimen and therefore reflect a magnified image, fluorescence microscope, on the other hand, uses more light. Intensity-wise fluorescence microscope implores more light to illuminate the specimen.
As light excites fluorescence within the sample, light is then emitted with longer wavelength. Also, this optical instrument produce images based widely on second illumination source, which is the light originating from the fluorescent species rather than from the original light which excited the sample.
Inverted microscopes, especially inverted fluorescence microscopes, are useful in observing organisms like living cells at the bottom of a big container such as a tissue culture flask. Such manner of viewing the specimen under the microscope is more of a natural condition than in the case of conventional microscopes, which make use of glass slide.
The Cell Theory and Inverted Fluorescence Microscopes
Thanks to Matthias Jakob Schleiden and Theodor Schwann the cell theory was developed in 1839. Through the cell theory cells are not only classified, but also further identified. Withotu this basic discovery and concept of cells many conditions and diseases will remain unknown to man.
We knew more than just the origin of the word (Latin, cellula), through latest innovations on experiment and scientific instruments cells are further known. Through the help of optical instruments such as the inverted fluorescence microscope we discover more about the minute particles invisible to our naked eyes.
Basic Requirements of Inverted Fluorescence Microscopes
Since we know that an inverted microscope is an optical device that has its light source and condenser atop, while objectives and turret are below the stage pointing up let us now take a closer look on how the principle of inverted fluorescence microscopes work.
Like other fluorescence microscopes, the inverted fluorescence microscope uses objective lens to serve two distinct functions—to focus the illumination on the sample and to gather the emitted fluorescence. Both functions are principles used in cell observation.
So as to excite the fluorescent species within the specimen, the optics of an inverted fluorescence microscope must concentrate the illumination light on the sample. This is done extensively compared to how the traditional condenser lens system located at the illumination light path of the usual microscope.
Gathering of emitted fluorescence is a kind of excitation-emission pattern where in epifluorescnce happens—both excitation and emission light travel through the objective.
Cell Observation and Inverted Fluorescence Microscope
When we were in high school our biology teacher told us the basic information about cells—how they are studied and how they must be viewed under microscopes. We knew from back then that the cell is the basic structural and functional unit of known living organisms. For this reason alone, it has been termed as the “building block of life.”
Organisms may be unicellular or multicellular. Bacteria are unicellular since they consist of a single cell, while we humans are multicellular because we have within us complex systems grounded on different types of cells. By that time we are already aware of how important cells are to our life.
The realm of medicine knows this greatly, since cervical cancer and other life threatening diseases are diagnosed through cell observation using microscopes such as inverted fluorescence microscope. Without the help of microscopes cells will not be analyzed and diseases will not be diagnosed.
Also, without the inverted fluorescence microscope further details and explorations on cell observation will not prosper. There need to be a device to launch and trek such discoveries. Studies will not materialize without any optical instruments.
Cell observation using inverted fluorescence microscope is now a must for physicians and medical practitioners. Gone were the days that traditional simple light microscopes are used to examine cells and other minute specimen.
