Science background with molecule or atom

A molecular model of the plasticizer Dibutyl Phthalate or DBP. As a plasticizer it has been used in many products including adhesives, textiles, cosmetics and children's toys. There are now concerns about its health effects, particularly its effect on male health and behaviour. Isolated on white.

Squalane is a hydrocarbon derived by hydrogenation of squalene. 3d illustration

Close-up shot of a petri dish for checking an antibiotic in the laboratory.

3d rendering of benzene molecules conjugated gold (Au) nanoparticles (NPs) on the black background

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.

Candida is the most common fungal pathogen, with Candida albicans and Candida tropicalis accounting for 90% of the infections.

The study of plant tissues under the microscope in the laboratory.

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.
