nanotechnology and abstract graphene structures

Nucleosome structure. Structure of an oligonucleosome, showing the packaging of DNA in chromosomes. 3D illustration.

A ball and stick + ribbons model of beta-secretase - a protein that is important in forming healthy peripheral nerve cells, but is also involved in the onset of Alzheimer's disease.

Copper(II) sulfate with molecular structure. Chemical ingredient used in medical and public health issues.

After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.

3D realistically coloured hexagonal shapes of connected spheres, background with copy space. Futuristic illustration design template for scientific presentation. Molecular business, science, teamwork concept.

$Antibodies conjugated with drugs at the FC region are designed to attach a drug to the FC region of the antibody. This technology leverages the specificity of antibodies to deliver the drug directly to target cells. As a result, it can enhance the drug's effectiveness and reduce side effects. This approach is particularly promising in cancer treatment and therapies for autoimmune diseases.\n\nThis image was not created by AI.$

3D rendering of biotinylated antibody, an engineered protein designed to bind to specific molecules. Biotin allows researchers to easily track and manipulate these antibodies.

Chemical formula of ATP on a futuristic background

The cytokin interleukin 11 (IL-11) plays an important role in autoimmune diseases, fibrotic complications, and solid cancers. Blocking IL-11 can extend lifespan and improve health.

A ball and stick model of a strand of a molecule of polyvinyl chloride, more commonly known as PVC. This vinyl polymer is one of the commonest plastics in use.
