NOVEL NANOPARTICLES BASED ON XYLAN

摘要

In recent years,several studies have been devoted to the formation and characterization of nanoparticles based on polymers.Novel xylan esters were efficiently synthesized by conversion of the biopolymer with furan and pyroglutamic acid and N,N'-carbonyldiimidazole as activating agents,under homogeneous conditions,in dimethyl sulfoxide.By a simple dialysis process,the xylan ester forms spherical nanoparticles of sizes as low as 60 nm,characterized by a narrow particle size distribution.
