A responsive porous hydrogel particle-based delivery system for oncotherapy

Area of Science:

• Biomaterials Science
• Oncology
• Drug Delivery

Background:

• Liver cancer poses a significant threat to human health.
• Current chemotherapy for liver cancer faces challenges like uncontrollable drug infusion.
• Responsive materials are needed to improve drug delivery and treatment outcomes.

Purpose of the Study:

• To develop novel responsive porous hydrogel microparticles for liver cancer therapy.
• To investigate the co-delivery of 5-fluorouracil and metformin using these microparticles.
• To evaluate the controlled drug release and loading efficiency of the developed system.

Main Methods:

• Synthesis of porous hydrogel microparticles using temperature-responsive pNIPAM.
• Loading of 5-fluorouracil and metformin into the porous microparticles.
• Evaluation of drug loading efficiency, sustained release, and temperature-responsive release behavior.

Main Results:

• The porous microparticles demonstrated high loading efficiency for both 5-fluorouracil and metformin.
• Sustained and controllable drug release was achieved, triggered by tumor microenvironment temperature.
• The microparticles protected the loaded drugs from degradation, ensuring stability.

Conclusions:

• Responsive porous hydrogel microparticles show great potential for effective liver cancer oncotherapy.
• The developed system offers a promising strategy for overcoming limitations of conventional chemotherapy.
• This approach facilitates efficient co-delivery and controlled release of anti-cancer drugs.
