Abstract

âº N,O-acetylchitosan was linked to steroids and vitamin E for controlled release. âº Resulting conjugate formed self-assembled nanoparticles in aqueous solution. âº Almost constant release rates were observed during the first 6-8Â h. âº Brassinosteroids-modified nanoparticles showed good agrochemical activity. âº Tocopheryl-modified nanoparticles exhibited antioxidant activity in DPPH test.
