Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics  from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet),  ampicillin (red).
A ball and stick model of a Polytetrafluoroethylene molecule, also known as PTFE or most commonly Teflon. It is a polymer consisting of only carbon and fluorine atoms. It is used as a non-stick coating for cookware, as a lubricant, and it is also used to contain highly reactive chemicals as it is extremely non-reactive.
