Biopolymers offer a sustainable alternative to synthetic polymers for drug delivery. Researchers developed novel biopolymer matrices using coacervation, showing promise for controlled release applications.

Area of Science:

  • Materials Science
  • Biotechnology
  • Drug Delivery

Background:

  • Biopolymers are explored as alternatives to synthetic polymers for drug delivery systems.
  • Their ability to encapsulate hydrophilic and hydrophobic drugs is advantageous.
  • Environmentally friendly production methods are desirable for industrial applications.

Purpose of the Study:

  • To develop and evaluate novel biopolymer-based matrices for controlled release applications.
  • To investigate the potential of biopolymers derived from proteins and polysaccharides.
  • To explore hydrogel systems as a source for new drug delivery particles.

Main Methods:

  • Utilized simple or complex coacervation methods with proteins or protein-polysaccharide mixtures.
  • Created new matrices for controlled release applications.
