Skin cell background with cosmetics concept, 3d rendering. 3D illustration.
A molecular model of Bisphenol A or BPA.  It is a common building block in the production of many epoxy resins and plastics including polycarbonate plastic. As such it is present in a huge range of food packaging and household products. There are now concerns about its health effects, particularly its effect on children, infants and fetuses.   Isolated on white.
Squalane is a hydrocarbon derived by hydrogenation of squalene. 3d illustration
Urothelial carcinoma, high grade.  High-grade tumors have an aggressive appearance under a microscope and are assumed invasive in the kidney or ureter.

Leiden leaf c.s. under microscope
Slice of natural crystal for patterns and textures use with high resolution.
Planarian parasite (flatworm) under microscope view.
Simuliidae, black fly (Diptera) in Baltic amber, Eocene, approximately 56 - 34 million years ago. Image taken with extreme macro and focus stacking technique.
A petri dish with common yeast and bacteria colonies.
Structural model of Benzene molecule
Microalgae under microscopic view, green algae, cyanobacteria, phytoplankton, diatom, algae mix collage background
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.
Prostaglandin D2 or PGD2 is a prostaglandin that binds to the receptor PTGDR as well as CRTH2. 3d illustration
Bone marrow plasma cells .Plasma cell neoplasms are diseases in which the body makes too many plasma cells. Plasma cell neoplasms can be benign or malignant. Diagnosed with Immunostain CD138 positive.
Plant tissue Structure, section (tissue) of stem plant tissue under a light microscope.
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. Turquoise, blue
Gambusia is a large genus of fish in family Poeciliidae. Gambusia contains over 40 species, most of which are principally found in freshwater habitats, though some species may also be found in brackish or saltwater habitats.
Close-up shot of a petri dish for checking clear zone an antibiotic in the laboratory.
Omega-3 fatty acids, docosahexaenoic acid (DHA) molecule with oil background 3d rendering
Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
