Epithelial Cells in urine sediment.
Volvox microorganism from a microscopic lens.
plant Zea Stem C.S. under light mircoscope with white background
Photomicrograph of one celled amoeba. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
Background of mold in the wood of the house.
Lichen, Fungus, cross section slide under the light microscope view for education biology.
Urothelial carcinoma, high grade.  High-grade tumors have an aggressive appearance under a microscope and are assumed invasive in the kidney or ureter.
Algae under microscopic view, Diatoms, phytoplankton, fossils, silica, golden yellow
Natural agate surfaces, suitable for backgrounds and wallpapers.
Squash preparation of stained onion root tip cells showing various stages of mitosis. Differential interference contrast optics on a Leica microscope, Image taken with the X40 objective lens.  Depth of focus is extremely shallow (just a few microns).  Differential interference contrast results in an optical slice horizontally through the specimen providing maximum possible resolution at this magnification and good contrast. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
Paps smear analysis: Superficial squamous cell, metaplastic squamous cell, koilocytes cell. HPV related change
Buccal smear showing squamous epithelial cells exfoliated from the oral mucosae. Small blue dots located mainly on the right cell are bacteria.
In vitro bacterial culture
Cell Division and Cell Cycle under the microscope.
Salmonella bacterium found to be sensitive to all antibiotics tested for.
Yeasts sprout in microscopy
Air bubbles under water. Air bubbles rise up in the water column.
Notoedres cati under the microscope. Notoedric mange, also referred to as Feline scabies, is a highly contagious skin infestation caused by an ectoparasitic and skin burrowing mite Notoedres cati.
Close-up shooting of a green agate stone mineral surface isolated on white background. Its a macro shot shows nature beautiful details with back lit. Agate is a kind of natural gemstone. Abstract pattern. Good for Wallpaper texture background. Purple
Squash preparation of  onion root tip cells stained to reveal chromosomes,  Bright field illumination, light microscopy.  This image was taken with the X40 objective lens.  Depth of focus is extremely low at this magnification.  Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced.  The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
Noctiluca scintillans algae cells algae under microscopic view, bioluminescent, bright blue glow on water at night, responsible for environmental hazards, toxic red tides and eutrophication
Host cells with spores (mold) are inside wood under the microscope for education.
Aspergillus fumigatus is one of the most common Aspergillus species to cause disease in individuals with an immunodeficiency. This pathogen primarily causes invasive infection in the lung.
Microscopic image of the operculum of a shrimp with possible disease. Research. Study. Laboratory. Aquaculture. Findings of disease in shrimp.
Rest of coffee was forgotten in the carafe for a couple of days and mold appeared.
The wet petals
Close-up shooting of a green agate stone mineral surface isolated on white background. Its a macro shot shows nature beautiful details with back lit. Agate is a kind of natural gemstone. Many vibrant colors turquoise, orange, blue, yellow, green. Abstract pattern. Good for Wallpaper texture background.
