fluoro

Fluoro is a term used across science and industry to indicate fluorine-related concepts. In chemistry, the prefix fluoro- denotes the substitution of a hydrogen atom by fluorine within a molecule. Fluorine, symbol F, is the lightest halogen and the most electronegative element. The carbon–fluorine bond is among the strongest in organic chemistry, often imparting metabolic stability and altered lipophilicity to fluorinated compounds. Fluorinated materials, including fluoropolymers such as PTFE, are valued for chemical resistance, low friction, and nonstick properties, and they find wide use in coatings, seals, and industrial components.

In medicine, "fluoro" is an informal shorthand for fluoroscopy, a real-time X-ray imaging technique. Fluoroscopy directs X-rays through the body while an image is displayed live on a monitor, frequently with iodinated contrast agents. It is widely used to guide interventional procedures, evaluate swallowing or tract patency, and assist gastrointestinal investigations. Because it involves ionizing radiation, clinicians minimize exposure using shielding, dose management, and modern digital imaging systems.

Beyond chemistry and imaging, "fluoro" appears in discussions of fluorinated polymers, agrochemicals, and pharmaceutical design. Some fluorinated compounds are persistent in the environment and are subject to regulatory scrutiny; PFAS, for example, have drawn attention for their persistence and potential health effects. Fluorine chemistry thus spans practical applications and safety considerations, with ongoing research to balance functional benefits against environmental impact.
