A chemistry coil is a tube of spiral form, used commonly to cool originating stéam of the distillation and thus to condense them in liquid form.  In the study of how molecules interact with each other, there are a few specific references to organic coils.  During self-assembly,  organic elements organize to form this structural pattern. Molecular self-assembly assembles the molecules, without guidance or management from an outside source, into these shapes.

Examples of these structural patterns include:

A coiled coil is a structural motif found in many proteins.

The DNA coil is a nucleic acid structure that contains  the genetic instructions specifying the biological development of all cellular forms of life (and many viruses).

A random coil is a polymer conformation where the monomers are arranged at random.

The RNA coil is a nucleic acid structure consisting of a string of covalently-bound nucleotides.

As an acronym, COIL denotes the Chemical Oxygen Iodine Laser.

In medicine, the Guglielmi Detachable Coil is a platinum coil commonly used in intracranial non-invasive surgery, for the occlusion of brain aneurysms.
