Claim:
1. A method of producing feather nanoparticles from waste chicken feathers, the method comprising steps of: pretreating a plurality of waste chicken feathers; hydrolyzing a plurality of waste chicken feather fibers enzymatically; analyzing effects of an enzyme concentration, a hydrolysis time and a substrate concentration on particle size; and producing feather nanoparticles according to a particle shape, a particle size, crystallinity index and thermal stability characteristics, and wherein the steps of producing the feather nanoparticles comprises: suspending a centrifuged particle fraction in distilled water for determining a particle size distribution, and wherein the particle size distribution is determined by a particle size analyzer; subjecting centrifuged particles to ultrasonic treatment for 15 min at 80% amplitude; and characterizing physicochemical properties of the produced feather nanoparticles.
