What is Electron Microscopy

Electron microscopy is a powerful technique used to study the ultrastructure of cells and tissues. It uses a beam of electrons to create00 high-resolution images, allowing for detailed examination of cellular organelles, membranes, and other structures at the nanometer scale. There are two main types of electron microscopy: transmission electron microscopy (TEM) and scanning electron microscopy (SEM). TEM is used to visualize internal structures of cells and tissues, while SEM provides detailed 3D surface images. Both techniques are widely used in various fields of research, including cell biology, pathology, materials science, and nanotechnology.


 Electron microscopy is a technique that uses a beam of accelerated electrons to examine objects on a very fine scale. It allows for much higher magnification and resolution compared to light microscopy, enabling the visualization of very small structures such as individual cells, organelles, and even large molecules. There are two main types of electron microscopy:

Transmission Electron Microscopy (TEM): In TEM, electrons pass through a thin specimen, and the resulting image is formed by the interaction of electrons transmitted through the specimen. This technique provides detailed information about the internal structure of the specimen and is commonly used in biological and materials science research.

Scanning Electron Microscopy (SEM): SEM scans a focused beam of electrons across the surface of a specimen, and the interactions of these electrons with the sample surface generate signals that can be used to create an image. SEM is particularly useful for studying the surface morphology of specimens in great detail.

Electron microscopy has been invaluable in advancing our understanding of biological structures, materials science, and nanotechnology, among other fields, due to its ability to provide high-resolution images at the nanometer scale.

  Pathology Lab Techniques: From Microscopes to Genetic Testing In the realm of pathology, the laboratory is where the magic happens. Pathologists and lab technicians use a variety of techniques and tools to uncover the mysteries of disease. In this blog post, we'll take a journey through the various lab techniques that play a pivotal role in pathology : Microscopy in Pathology : Begin with an exploration of how traditional light microscopy remains the backbone of pathology, allowing pathologists to examine tissue and cellular structures in detail. Histopathology : Delve into the art of preparing and staining tissue samples to visualize cellular structures and identify abnormalities, making it the cornerstone of diagnosing diseases. Cytopathology : Discover how the examination of individual cells from various bodily fluids, like Pap smears, plays a crucial role in cancer detection and diagnosis. Immunohistochemistry (IHC): Learn how IHC uses antibodies to identify spec...

What is pathology? Pathology is a branch of medical science that involves the study and diagnosis of diseases. It focuses on understanding the nature and causes of diseases, as well as the structural and functional changes that occur in tissues and organs as a result of these diseases. Pathologists, medical professionals specialized in pathology, play a crucial role in diagnosing illnesses, guiding treatment decisions, and understanding the underlying mechanisms of various health conditions.

Track 11: Cancer Cytopathology

Image
What types of cytology? Cytology encompasses various specialized fields and techniques tailored to different areas of study and medical practice. Here are some common types of cytology: Diagnostic Cytology: This involves examining cells obtained from different body tissues or fluids to diagnose diseases, such as cancer, infections, or inflammatory conditions. It's often used in conjunction with histology (the study of tissues) to provide a comprehensive diagnosis. Gynecologic Cytology: This branch focuses on examining cells collected from the female reproductive system, primarily the cervix, for the early detection of cervical cancer and other abnormalities. Pap smears are a common example of gynecologic cytology used for cervical cancer screening. Non-Gynecologic Cytology: This includes the examination of cells obtained from sites other than the female reproductive system. It encompasses various body fluids and organs such as the respiratory tract (sputum cytology), thyroi...
