Application


  • Improving the effectiveness of (-)-epigallocatechin gallate (EGCG) against rabbit atherosclerosis by EGCG-loaded nanoparticles prepared from chitosan and polyaspartic acid.: This research highlights the development of nanoparticles using polyaspartic acid to enhance the bioavailability and therapeutic effect of EGCG in treating atherosclerosis (Hong et al., 2014).

  • Polyaspartate, a biodegradable chelant that improves the phytoremediation potential of poplar in a highly metal-contaminated agricultural soil.: The study evaluates the use of polyaspartate in enhancing the phytoremediation capabilities of poplar trees, showcasing its environmental application for soil decontamination (Lingua et al., 2014).

  • Modulation of calcium oxalate dihydrate growth by selective crystal-face binding of phosphorylated osteopontin and polyaspartate peptide showing occlusion by sectoral (compositional) zoning.: This research investigates the role of polyaspartate in modulating the growth of calcium oxalate crystals, with implications for understanding kidney stone formation (Chien et al., 2009).

A new class of biodegradable poly-amino acid, alpha,beta-poly[(N-hydroxypropyl/aminoethyl)-DL-Aspartamide-co-L-Lysine] (PHAAL), was synthesized by ring-opening of poly[succinimide-co-lysine](PSL) with n-propanolamine and ethylene diamine after thermal copolycondensation of DL-Aspartic acid and L-lysine under reduced pressure. Different ratio feeds of PSL were obtained and characterized
