Self-therapeutic metal-based nanoparticles for treating inflammatory diseases

Area of Science:

• Nanomedicine
• Materials Science
• Biomedical Engineering

Background:

• Inflammatory diseases cause significant global mortality and reduced quality of life.
• Conventional treatments like corticosteroids and biologics have limitations including systemic toxicity and infection risk.
• Existing nanomedicine approaches face challenges with particle size, leading to systemic clearance.

Purpose of the Study:

• To review the emerging applications of self-therapeutic metal-based nanoparticles for inflammatory diseases.
• To focus on therapeutic outcomes and anti-inflammatory mechanisms of these novel nanoparticles.
• To provide an outlook on their clinical translation, including biodistribution and toxicity.

Main Methods:

• Literature review focusing on research from the past three years.
• Analysis of metal-based nanoparticles (gold, copper oxide, platinum, ceria, zinc oxide) with intrinsic anti-inflammatory properties.
• Evaluation of therapeutic outcomes and mechanisms in animal models.

Main Results:

• Metal-based nanoparticles are compact, facilitating biological barrier crossing and acting as dual carriers/drugs.
• These nanoparticles enable label-free tracking of cellular interactions.
• Emerging applications show promise in managing inflammatory diseases with potential for lower toxicity.

Conclusions:

• Self-therapeutic metal-based nanoparticles represent a promising alternative to conventional anti-inflammatory therapies.
• Their compact nature and dual functionality offer advantages in drug delivery and tracking.
• Further research into biodistribution, long-term toxicity, and clinical translation is crucial for their development.
