This study developed a novel nanocomposite hydrogel using a peptide and hyaluronic acid to effectively deliver quercetin. The new system enhances quercetin
Area of Science:
- Biomaterials Science
- Nanotechnology
- Food Science
Background:
- Traditional protein-based delivery systems struggle with bioactive compound stability during food processing and storage.
- Instability of bioactive compounds necessitates advanced delivery systems for enhanced efficacy.
Purpose of the Study:
- To develop and characterize a nanocomposite hydrogel for quercetin delivery.
- To investigate the impact of quercetin co-assembly on hydrogel properties.
- To evaluate the encapsulation efficiency and controlled release kinetics of quercetin.
Main Methods:
- Co-assembly of self-assembling peptide (Fmoc-FRGDF) and hyaluronic acid (HA) to form a nanocomposite hydrogel.
- Systematic investigation of hydrogel stability as a quercetin (Que) delivery carrier.
- Characterization of microstructural evolution, physicochemical properties, encapsulation efficiency, and release kinetics.
Main Results:
- Hyaluronic acid modulated hydrogel's storage modulus and significantly slowed degradation rates.
- Quercetin enhanced the hydrogel's storage modulus, indicating improved structural integrity.
- Co-assembly involved hydrogen bonding, electrostatic, and hydrophobic interactions, strengthening beta-sheet structure and supramolecular ordering; Que release followed Korsmeyer-Peppas kinetics.
Conclusions:
- The Fmoc-FRGDF/HA hydrogel system is a superior delivery vehicle for quercetin, maintaining its bioactivity.
- This peptide-polysaccharide-polyphenol ternary complex offers a multifunctional platform for bioactive agent encapsulation and controlled release.
- Polyphenol incorporation positively impacts rheological properties, microstructure, and supramolecular organization.
