fibriller

Fibriller is a term encountered in scientific and technical contexts that relates to fibrils—those slender, fiber-like structures formed by polymers, proteins, or composites. In some languages, fibriller can function as a noun referring to a fibril, or as a verb meaning to form or convert material into fibrils (fibrillation). In English, the common terms are fibril and fibrillation, and fibriller may appear mainly as a loanword or in bilingual texts rather than as a standard term.

In biology, fibrils are fundamental structural elements. They appear as actin filaments in the cytoskeleton, collagen fibrils in connective tissue, and various other protein fibers that contribute to cell shape, mechanics, and tissue organization. Fibrillization is the process by which proteins assemble into elongated fibers, a mechanism relevant to normal physiology as well as certain diseases when misfolded proteins aggregate into amyloid fibrils.

In materials science and engineering, fibrillation describes the formation of fibrous structures from polymers or composites. Methods such as mechanical processing, chemical pretreatment, or nano-scale processing can produce microfibrils or nanofibrils from cellulose, synthetic polymers, or other materials. Fibrillar networks can enhance strength, toughness, barrier properties, or functional surfaces in fabrics, films, and \(bio\)-based materials.
