There was an extra control slide so that the microscope could be adjusted without harming the samples. The cover slip was placed on top and nail polish was added to the sides of the cover slip to prevent the sample from drying out. With the 40x lens of the Zeiss Axiovision Widefield Fluorescence Microscope, images of the cells were captured. The two channels that were used were DAPI and DIC. DAPI had an exposure time of 960…

water under the microscope. Taking note of their size, movements, and characteristics to classify the different types of protists from applying previous knowledge of protists. Materials: The materials in this lab that will be needed are a microscope, slide, coverslips, a pipette, and a dish of pond water. Procedure: Prepare a slide by using the pipette to apply two drops of pond water on a slide and properly place a coverslip. Place the prepared slide under the microscope to view and…

 Introduction.  Parts of light microscope.  Steps to setup light microscope.  Uses of light microscope.  How to clean light microscope.  Maintain the light microscope.  Summery.  References. Introduction. Light microscope is an instrument which used to magnify small specimen which cannot be seen through naked eye, by using a light source. It helps to magnify the small object to 1000* times than the real size of the real object. In light microscope light ray is send and it…

Then, observations were made of the mCherry fluorescence under a fluorescent microscope with a “Flur 20X” objective and FIT-C Filter Set, which produced green light and made the specimen’s basal body formation glow red (shown in Fig. 6). Each strain of fixed cells was prepared on a separate wet mount slide, and the observations made…

Created by Ernest Ruska and Max Knoll of the Berlin Technische Hochschule in 1931, the invention of this novel microscope allowed for the surpassing of the visible light resolution barrier. Since its inception, the TEM has become a resolution standard in the field of imagery, and further advances have led to the progression of high quality atomic viewing. The development of the electron microscope in the 1930s revolutionized biology, allowing for organelles, such as mitochondria, to be seen in…

Microscope Essay Carolyn, 6C 20 November 2015 Microscopes How has the microscope helped our understanding of science and changed the world? The microscope has developed a huge understanding of science and really changed the world. Microscopes magnify tiny objects, which make them look a lot larger. Scientists use microscopes to see tiny objects that are too small to see with our eyes. These include cells, tiny living things, and grains of sand. A compound light microscope can give a…

the area of the microscope where it can be scanned. Sometimes this means only rather small areas or portions of a sample can be analyzed at one time (1). Another important environmental factor to consider when performing SEM is that atoms in the air can affect the electron behavior too, so the analysis must be done in a vacuum. This prevents certain types of samples from being tested, specifically those in a watery environment or those that are unstable (2). Typical SE microscopes cannot analyze…

There are many different ways medical technology has progressed over the last one hundred years in Canada. The discovery of insulin helped doctors save many lives. The invention of the electron microscope changed the way scientists were able to view many different things including very small organisms. The invention of the external pacemaker saved many lives back in 1950, one of the inventors needed his own invention to save his life for some time. The discovery of the Cystic Fibrosis also…

appropriateness of light and electron microscopes for different purposes. Explain the difference between magnification and resolution (2) Magnification is how much you can enlarge an image Resolution is how sharp and clear your microscope can show an image State the resolution that can be achieved by each of the following types of microscope (2) Light microscope. 200nm Transmission electron microscope. 0.5nm Explain the appropriateness of light and electron microscopes for…

Chromium (Cr) is one of the most toxic chemical compounds due to the common use of chromium compounds in industry in addition to its natural sources (Costa et al., 2003). Exposure to chromium occurs via contaminants found in drinking water and food, through air containing particulates or mists of hexavalent chromium Cr (VI) compounds, or through skin contact with soil at hazardous waste sites (National Institute for Occupational Safety and Health, 2013). Cr (VI) may be found in drinking water…
