Microscopy Summary The entire exercise was all about caring for and using the microscope. We performed various activities that enabled us to familiarize ourselves with the parts and uses of the microscope. Using the microscope, we observed different objects such as cotton, silk, hair, and even a letter "e." We viewed it using both the low power objective and the high power objective. We did these activities in order to better understand how the compound light microscope works and also to
Microscopy allows one to view samples and objects that cannot be seen with the human eye. With all the modern techniques used in the biology field today, microscopy is one of the most important one that allows us to see a world beyond what our eyes limits us too. The majority of both organisms that are helpful and harmful are too small to be seen with the human eye, and without the microscope we would have not understood the mechanism behind the major diseases we know today. Microscopy has helped
probe microscopy in nano mechanical testing has started with the invention of the scanning tunneling microscope in the year 1981. Till then based on the type of principles there are number of models developed and are in use. Scanning probe microscopy found popularity owing to its ease in versatility in dealing with a number of issues, typically it is used to identify the material properties on nano to even pico scales. Scanning probe microscopy techniques such as atomic/friction force microscopy(AFM/FFM)
magnified. Light microscopy was first used to magnify the image of the cells using stains. However, some tissue and subcellular structures are too small to be seen even under the light microscope. Therefore another technique was found to visualise the cell in more details. To study the smaller features of the cell, electron microscopy are used. Electron microscopy use electron beam to visualise the specimen. Electron microscopy can only magnify thin structures, therefore fluorescent microscopy are used
Dr. Joseph Henry Wythe (1822-1901) was born in Manchester, England on March 19, 1822, the son of Joseph Wythe and Mary Chamberlain. In 1832, JH Wythe accompanied his parents to America, and began his education in the private schools of Philadelphia where the family had settled. Through his own efforts and supplemented by private instruction, he became proficient in the natural sciences and the languages of Greek, Hebrew and Latin. In 1842, JH Wythe became an ordained Methodist minister at the early
industrialized nations, and a major medium of communication and source of home entertainment. Television is used in many industries. A few examples are for surveillance in places inaccessible to or dangerous for human beings, in science for tissue microscopy, and in education. Today you can find a television in almost every home. This is why I decided to research the history of the television. The first television devices were based on an 1884 invention called the scanning disk, patented by Paul
Microscopy is the technical field of using microscopes which is a device that views object or specimen that are too small to be seen with the naked eye. In history, optical microscope is the first microscope to be developed containing one or more lenses producing an enlarged image of a sample placed in the focal plane by unidentified person. With the advancement of technology, compound microscopes that we are using today were claimed to be invented by Zacharias Jansen. Compound microscope is a microscope

Arabidopsis Culture Cell and Transformation Arabidopsis thaliana (L.) Columbia ecotype suspension- cultured T87 cells were maintained at 22°C in JPL3 medium with continuous illumination and shaking at 100g. Two-week-old cells were sieved through 500 μm stainless mesh and the remaining filtrate was transferred to a flask containing 20 ml of fresh JPL3 medium for subculture. Transformation of T87 cells was done by culturing the cells in B5 medium supplemented with 1 μM 1-naphthaleneacetic acid (NAA)
although they behave as if they are attached to each other. The individual chains are actually held together by ‘Electrostatic Forces’ between molecules, also known as ‘Hydrogen Bonds’. Scientists discovered this, by using a special type of X-ray microscopy called ‘XANES’. This was able to reveal the orientation of molecules in materials. It has also been discovered that the components of Kevlar fiber, have a radial orientation that is in a crystal. The crystal-like regularity is the largest contributing
DISCUSSION In this experiment, we had been able to learn the proper technique of using the optical microscope and preparation of different types of slides. Optical microscope, often referred to as light microscope, is a type of microscope which uses visible light and a system of lenses (4X, 10X, 40X and 100X) to magnify images of small samples. Image from an optical microscope can be captured by normal light-sensitive cameras to generate a micrograph. Microscope is one of the best technology provide

biology sees follows closely with the development of new technology. It is very important to understand and visualise the composition and structures of biological materials or samples in order to extend and correlate this to the principles of life. Microscopy is a by far the most used and the most relevant technique in this regard. However the short comings in the technological aspect of this greatly limit the usage of this to comprehend the specifics. Through the advancement of the analytical techniques
MICROSCOPY Microscopy is the technique to examine minute objects through microscope which can not be seen by naked eye. (1) HISTORY OF MICROSCOPY SCIENTIST YEAR CONTRIBUTION Hans and Zacharias Janssen 1590 Created first microscope Robert Hooke 1667 Published micrographia Anton van leeuwenhoek 1675 Used microscope with one lens. He was first to observe bacteria. Joseph Jackson lister 1830 Discovered that weak lenses in combination provide clear magnification Richard zsigmondy 1903 Invented ultra
The word microscope is often used to define an instrument used for viewing small objects, such as bacteria, minerals, and cells that can’t be seen with the naked eye by magnifying them using a series of lenses. Microscopes vary from models and styles, but each consists of similar parts including lens, eyepiece, stage, adjustment knobs, light, nosepiece, and arm. The eyepiece allows an individual to look through it to view samples. Usually the magnification of an eyepiece 10x. The arm supports the
Introduction Daphnia are planktonic crustaceans2, more commonly known as a water flea. They are microscopic and most commonly found in ponds or lakes. These fleas have flat leaf-like legs that help them move through the water2. Male Daphnia are smaller than female but have larger antennules and their first legs have hooks that are used for clasping2. In spring and summer female Daphnia are more commonly found than male1. Female Daphnia can fertilize without male1. A male Daphnia is more common
Lab Work Not Included The purpose for completing this lab was to observe how microscopes function. The invention & evolution of the microscope has been an ongoing process since the Middle Ages, when the first convex magnifying lenses were introduced. In 1590, the Jansen Brothers invented the first compound microscope (two or more lenses).However, Antony van Leevenwenhoek created the first “true” microscope, in 1665, with 300x magnification & unbelievable resolution. During the late 1700’s, the
Scanning electron microscopy (SEM) technique was employed extensively through want this study to examine and obtain images of prepared samples. The associated analytical facility of Energy dispersive X-Ray (EDX) analysis was used to identify and quantify the elemental composition of the prepare samples. These different techniques are essentially part of one instrument. The EDX facility (an X-Ray detector and associated software) is incorporated intimately as part of the SEM itself. The EDX facility
Fluorescence Microscopy and Study of Fluorescence Labelled Developing Heart of Chick Embryo Introduction: Fluorescence: The fluorescence microscopy is a kind of optical microscopy in which the phenomena of fluorescence instead of, or in addition to, reflection and absorption are used to generate the image of the specimen under study. When organic or inorganic specimens absorb photon from a radiation of shorter wavelength (UV or visible spectrum), get excited and subsequently emit light of longer
