Summary
This study developed dual-stimuli-responsive nanocarriers from biocompatible polymers. These nanocarriers show controlled release of encapsulated drugs in response to lipase or UV light, demonstrating potential for advanced drug delivery.
Area of Science:
- Biomaterials Science
- Polymer Chemistry
- Nanotechnology
Background:
- Stimuli-responsive polymers are crucial for targeted drug delivery.
- Developing biocompatible and dual-stimuli-responsive nanocarriers remains a challenge.
Purpose of the Study:
- To design and synthesize dual-stimuli-responsive multi-amphiphilic polymeric architectures.
- To evaluate their self-assembly, cargo encapsulation, and controlled release capabilities.
- To assess their potential as non-cytotoxic nanocarriers for biomedical applications.
Main Methods:
- Copolymerization of PEG-diester and azido-triglycerol using a biocatalyst.
- Grafting with azobenzene and polyglycerol dendron moieties.
- Encapsulation of Nile red probe and investigation of controlled release via lipase and UV light.
Main Results:
- Synthesized multi-amphiphilic polymers capable of self-assembly and cargo encapsulation.
- Demonstrated controlled release of Nile red, with significant release in the presence of lipase and faster, albeit lesser, release with UV light.
- Confirmed non-cytotoxicity up to 500 μg/mL for 72 hours.
Conclusions:
- The developed dual-stimuli-responsive nanocarriers show promise for controlled drug delivery.
- Their biocompatibility and stimuli-responsive release mechanisms make them suitable for advanced nanomedicine applications.
- Further investigation into their therapeutic potential is warranted.
