Summary
Researchers developed stable protein-polysaccharide nanogels using maleic anhydride chitosan (MAC) and bovine serum albumin (BSA). These MAC/BSA nanogels show potential as drug delivery carriers, demonstrating antimicrobial properties when loaded with amoxicillin (Amox).
Area of Science:
- Biomaterials Science
- Nanotechnology
- Polymer Chemistry
Background:
- Protein-polysaccharide systems offer unique properties for biomedical and pharmaceutical applications.
- Chitosan derivatives and bovine serum albumin are promising biopolymers for nanocarrier development.
- Self-assembly is a key strategy for creating stable nanostructures.
Purpose of the Study:
- To prepare and characterize novel nanogels from maleic anhydride chitosan (MAC) and bovine serum albumin (BSA).
- To investigate the self-assembly process, stability, and physical properties of MAC/BSA nanogels.
- To evaluate the potential of MAC/BSA nanogels as drug delivery systems, specifically for amoxicillin (Amox).
Main Methods:
- Nanogel preparation via self-assembly in an aqueous phase with varying MAC and BSA concentrations.
- Characterization using ultraviolet-visible (UV-VIS) spectrophotometry, dynamic light scattering (DLS), and zeta potential measurements.
- Assessment of nanogel properties including hydrodynamic diameter, pH-dependent behavior, and antimicrobial activity after amoxicillin loading.
Main Results:
- Thermodynamically stable MAC/BSA nanogels were successfully formed through self-assembly.
- Nanogel formation and conformational changes were influenced by MAC/BSA ratio and temperature.
- Hydrodynamic diameter showed slight increase at acidic pH, with zeta potential confirming protonation.
- Amoxicillin-loaded MAC/BSA nanogels demonstrated antimicrobial properties.
Conclusions:
- MAC/BSA nanogels represent a promising platform for developing advanced drug delivery systems.
- The study provides insights into the self-assembly mechanism and properties of these nanocarriers.
- These findings offer theoretical guidance for designing novel nanocarriers for diverse biomedical applications.
