Chitosan-Based Nanoparticles Against Viral Infections.

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Virology

Background:

• Viral infections can damage host cells and compromise the immune system, leading to persistent or relapsing infections.
• The complex viral life cycle presents challenges for developing effective antiviral drugs.
• Nanotechnology offers solutions to overcome limitations of conventional antiviral drugs, such as poor solubility and toxicity.

Purpose of the Study:

• To review the therapeutic potential of chitosan nanoparticles (NPs) against various viral infections.
• To highlight how nanotechnology, specifically chitosan NPs, can address challenges in antiviral drug development.
• To summarize evidence supporting chitosan NPs as novel antiviral therapeutic tools.

Main Methods:
