Invention of the New Microscope

Today, we’ll explore the invention of the microscope. In biology class, it brought a whole new world into focus. The microscope gave us technology and a better quality of life.

So it’s worth examining just how it came to be. Glass was invented about 22-hundred B-C. In the 1st century, Romans discovered if they made the glass thick in the middle and thin on the edges, objects viewed through it looked larger.

Microscopy technique could enable more informative biopsies

R&D team have devised a way to image biopsy samples with much higher resolution — an advance that could help doctors develop more accurate and inexpensive diagnostic tests.

For more than 100 years, conventional light microscopes have been vital tools for pathology. However, fine-scale details of cells cannot be seen with these scopes. The new technique relies on an approach known as expansion microscopy, developed originally, in which the researchers expand a tissue sample to 100 times its original volume before imaging it.

What is Optical Microscopy?

Optical microscopy is a technique employed to closely view a sample through the magnification of a lens with visible light. This is the traditional form of microscopy, which was first invented before the 18th century and is still in use today.

An optical microscope, also sometimes known as a light microscope, uses one or a series of lenses to magnify images of small samples with visible light. The lenses are placed between the sample and the viewer’s eye to magnify the image so that it can be examined in greater details.
