How are samples prepared for a transmission electron microscope?

Transmission Electron  Microscope (TEM)

What is transmission electron microscope? A transmission electron microscope (TEM) is an electron microscope that transmits electrons through a sample to observe it. Scientists use transmission electron microscopes to analyze materials and examine their microstructural and compositional properties. A transmission electron microscope transmits a highly focused beam of electrons through a sample to observe and … Read more

Light Microscope – Labeled Diagram, Definition, Principle, Types, Parts, Applications

Light Microscope - Labeled Diagram, Definition, Principle, Types, Parts, Applications

This reflects the seemingly marvelous developments that have occurred from the history of microbiology to the present day. Advances in technology and subsequent research in the field over the years have meant that once we learned how to study these tiny creatures, we only grew in appreciation for these vital little agents. But in 1590, … Read more

Inverted Fluorescent Microscope – Principle, Protocol, Parts, Uses

Inverted Fluorescent Microscope - Principle, Protocol, Parts, Uses

What is Inverted Fluorescent Microscope? Ever peeked into the world of living cells? Scientists use a nifty tool called an inverted fluorescent microscope for this. Unlike regular microscopes, this one flips the script—literally. Imagine the lenses sitting above the sample and the light source shining from below. This upside-down setup makes it perfect for studying cells chilling at the bottom … Read more

Microscope Slides Preparation Step By Step Guide

Microscope Slides Preparation Step By Step Guide

Objects are magnified under compound microscopes are mounted onto microscope slides. Made from plastic or glass Slides measure approximately 1×3 inches in size and range from 1mm-1.2 millimeters thick.

History of the Microscope

History of the Microscope

Microscopes have been around for the ages. Roman philosophers had mentioned “burning glass” within their works. However, the first microscope of this type was not invented until the 1300’s. Two lenses were set on opposite sides of the tube. This tube of magnifying power was the basis for our modern-day microscope.

Digital Microscope – Principle, Parts, Uses, Advantages

USB Microscope - Principle, Definition, Parts, Examples, Uses

Digital microscopes are modern microscope which does not have an eyepiece. This is a huge contrast from an optical microscope. Digital microscopes have an electronic camera that acts as the detector as well as the imaging output gadget. It displays the images takes place via a computer’s screen or monitor, which defines the scope of the microscope’s digital.

USB Microscope – Principle, Parts,Uses, Advantages

USB Microscope Principle, Definition, Parts, Examples, Uses

This is a form of digital Microscope which is connected to a computer using an USB port. It operates on low power. The camera is fitted with a powerful macro lens. Additionally, they have an integrated LED light that is built into the lens.

Atomic Force Microscope (AFM) – Principle, Parts, Procedure, Uses

Atomic Force Microscope (AFM) - Definition, Principle, Application

The AFM, also known as the atomic force microscope (AFM) is a sort scanner probe. Its principal functions include measuring characteristics like height, magnetism and friction.

Oil Immersion Technique – Objectives, Procedure, Types

Oil Immersion Technique

The oil immersion method enhances the resolving power of a microscope, enabling light microscopy to distinguish finer details. Immersion oil—clear and colorless, having a refractive index of about 1.515—is placed in between the lens and the specimen. The refractive index is higher; therefore, less light is refracted. If less light is refracted, then less is … Read more

Transmission Electron Microscope (TEM) – Principle, Parts, Uses

Transmission Electron Microscope (TEM)

What is transmission electron microscope? A transmission electron microscope (TEM) is a high-resolution imaging tool that uses a beam of electrons instead of light to see very small details in thin samples. It can make structures up to several million times bigger, which lets scientists see things like viruses, cell organelles, or even macromolecular complexes. … Read more
