Microscopy Research Papers Samples For Students

Optical microscopy – is the technical field of studying objects using optical microscopes. Optical microscopes are devices that use visible light rays as both eye works in the optical wavelength range. So, optical microscopes could not have diffraction limits resolution less than 0.2 micrometers (200 nanometers) and with maximum magnification up to 2000 times. The human eye is a biological optical system, characterized by a certain resolution - the smallest distance between the elements of the observed object, while they can still be distinguished from one another. For a normal eye, at a distance from the object to the so-called. best vision distance (D = ...

Introduction

The microscope is derived from two Greek words, mikros and skopeo. Mikros means small while skopeo means “look at.” Thus, the two words form the word mikroskopeo that refers to looking or observing small objects. Since the beginning of scientific developments, there has been an interest to look at the smaller details of the world around us. Biologists have taken the lead in the quest to uncover such small details through their desire to examine cells, viruses, bacteria, and colloidal particles. Material scientists have wanted to observe the limitations and inhomogeneities in metals, ceramics, and crystals. Geologists have also ...

Scanning electron microscope uses a beam of electrons to form images that reveal the topography and composition of a body. Before being focused on the object, incident electrons have high amounts of kinetic energy. Incident electrons interact with the surface of the specimen, and this interaction is determined by the rate of the acceleration of the incident electrons. Energetic electrons are usually released from the surface of the sample when the incident electrons come into contact with it. The interaction results in the formation of scatter patterns that interpret into the shape, composition, size, and texture of the specimen. ...

Abstract

The study of tiny particles and their applications have emerged as an important area of research in recent years. In particular, magnetic nanoparticles have attracted considerable attention due to their unique properties that make the particles useful in numerous applications. Accordingly, the present review investigates the synthesis, characterization, and biomedical applications of magnetic nanoparticles. The introduction section examines recent advances in nanotechnology and explains the significance of magnetic nanoparticles in scientific research. The section on results and discussion presents the findings of various researchers with a focus on the magnetic properties, synthesis, characterization, and biomedical applications of magnetic nanoparticles. ...

Abstract

In the field of medicine, histopathology process is undertaken by pathologist.The aim of undertaking histopathology is to examine the existence or the possibility of a disease in the body tissue of a living thing. In addition, the process of histopathology is best practiced on the specimen of body tissue taken during the surgery of a patient. Here, the process involves a series of activities where surgery helps to remove body tissues for examination. After the surgery, the body tissue removed is placed in a fixative place where no external toxicities can contaminate the specimen. This forms the basis for ...

George Emil Palade was a highly esteemed and a well renowned cell biologist of Romanian origin. He was born in 1912, in Moldavia, Romania. In 1974, he won the Nobel Prize in Physiology and Medicine for his pioneering work in Molecular biology. He shares this award along with Albert Claude and Christian de Duve. He was referred to as the "father of modern biology" and "the most influential cell biologist ever" for his innovative contribution to the field of cell biology.
While he was a medical student, he was invited by Albert Claude, the noble-winning biologist from the Rockfeller University who ...

Introduction

The founder of the Nobel price, Alfred Nobel was a distinguished scientist and investor. He owned a variety of firms that produced goods ranging from weapons to edibles. Thus chemistry was his field of study and specialization. When he died and introduced the Nobel peace prize, chemistry was the second prize area that he mentioned in his will. Thus the Nobel Prize in chemistry was founded. This prize is awarded annually by the Royal Swedish Academy of sciences in Sweden (Nobel Foundation, 2007).
The 2007 Nobel Prize was awarded to a Germany scholar and scientist Gerald Ertl for his successful research ...
