Synthesis of some amino acid functionalized Cellulose Nanowhisker and investigation their Antioxidant Behavior

Amino acids, the building blocks of peptides and proteins, belong to the simplest biomolecules. Apart from their role in protein–surface interactions [1], amino acids offer excitingpossibilities for functionalization of solid surfaces due to their multifunctionality and tendency for self organization and alsotheir antioxidant properties [2]. Synthetic macromolecules with antimicrobial and anti oxidant activities are often used in medical applications and foodpackaging, implants and wound dressing and medical textiles. Biopolymers as starch, cellulose, and their nanoparticles arepreferred over synthetic polymers for the development of various materials for two reasons: (a) they are based on annually renewable sources and abundantly available; (b) theyare biodegradable, and their production, use and disposal do not present environmental problems [3]. The aim of this workis Preparation of cellulose nanowiskers by acid hydrolysis as degradable bionano particle core and their modification withdifferent amino acids and investigation of their antioxidant behaviors
