Summary
Chitosan-lignosulfonate nanoparticles offer enhanced stability and biocompatibility for cosmetic and biomedical uses. These novel nanocarriers effectively deliver proteins, showing potential for advanced drug delivery systems.
Area of Science:
- Materials Science
- Biotechnology
- Polymer Chemistry
Background:
- Chitosan nanocarriers are recognized for their biocompatibility, biodegradability, and sustainability.
- Their application as drug delivery systems is well-established.
- Novel composite materials are needed to enhance chitosan nanocarrier properties.
Purpose of the Study:
- To develop novel chitosan-lignosulfonate nanoparticles for cosmetic and biomedical applications.
- To investigate the role of lignosulfonates as counter polyions for chitosan particle stabilization.
- To characterize the properties and performance of these new nanoparticles.
Main Methods:
- Chitosan-lignosulfonate nanoparticles were synthesized using high-intensity ultrasound.
- Particle size, zeta potential, and polydispersity index were measured.
- Biocompatibility with human cells, lysozyme degradation stability, and antimicrobial activity were assessed.
- Protein (RNase A) incorporation and release kinetics were studied.
Main Results:
- Optimized preparation conditions (pH 5, 8 min sonication, poloxamer 407) yielded nanoparticles with an average size of 230 nm and low polydispersity.
- Lignosulfonate incorporation significantly improved stability against lysozyme degradation.
- The composite nanoparticles demonstrated enhanced biocompatibility with human cells and antimicrobial activity.
- Hydrophilic protein (RNase A) was successfully incorporated, with release kinetics dependent on protein loading concentration.
Conclusions:
