Epithelial Cells in urine sediment.
Photomicrograph of one celled amoeba. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
Small interfering RNA or siRNA or short interfering RNA or silencing RNA. shRNAs consist of sense and antisense sequences separated by a loop sequence 3D rendering
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.
3D cartoon and Gaussian surface models, PDB 7cz5, putative membrane shown, white background
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.
An electron image of several nanoparticles made of lipids (liposomes) containing an anticancer drug (doxorubicin)
plant Stem of Nymphaea tetragona T.S. under light mircoscope with white background
Research method real-time PCR. 96-well plate on the background of amplification curves.
Natural agate surfaces, suitable for backgrounds and wallpapers.
Microscopic view of Dermatophytes. Nail scraping fungus. 100X
stx2a is a subtype of Shiga toxin-producing E. coli (STEC) linked to Hemolytic Uremic Syndrome (HUS), a severe condition impacting kidney function and blood clotting. STEC poses a significant risk of foodborne illness and can spread within communities including family members.
Several clusters of human Human Embryonic Kidney 293 cells in culture. These cells are a standard cell line used in biotechnology applications, for example to produce proteins. This view is as it appears through an inverted biological phase contrast microscope with 200x magnification.
Perfect shape of sponge cake.
3D cartoon and molecular surface models, chain id color scheme, putative membrane shown, pdb 7upt white background.
Ganglioneuromas are rare tumors that most often start in autonomic nerve cells. Autonomic nerves manage body functions such as blood pressure, heart rate, sweating, bowel and bladder emptying, and digestion. The tumors are usually noncancerous (benign).
Gram stain of the bacterium, Staphylococcus aureus. This bacteria is gram positive, as such it appears purple after staining due to the thick peptidoglycan. The round cells are also seen in clusters.
Abstract Crystal background marble shot, nature pattern.
Microscopic image showing oxalate crystals from urine sediment, most common cause of kidney stones
Photomicrograph of rotifer, probably Rotaria rotatoria. Rapidly rotating cilia at top of head, internal organs visible. Green circles are algae. Live specimen. Original image at 40X, wet mount, transmitted brightfield illumination. Indistinct image due to motion blur of live specimen and very shallow depth of field of brightfield illumination.
A micrograph of nanoparticles made of lipids containing an anticancer drug. The drug appears as a crystal inside of the spherical liposomes
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.
