Platinum nanoparticles in nanobiomedicine

Area of Science:

• Biomedical Engineering
• Materials Science
• Nanotechnology

Background:

• Oxidative stress-driven inflammatory diseases are a global health challenge.
• Biocompatible nanomaterials with enzymatic properties offer therapeutic potential.
• Platinum nanoparticles (PtNPs) exhibit catalytic activity beneficial for reducing reactive oxygen species (ROS).

Purpose of the Study:

• To review the anti-inflammatory capabilities of PtNPs.
• To explore their applications in nanomedicine.
• To critically assess synthesis methods, biocompatibility, and toxicological profiles.

Main Methods:

• Comprehensive literature review of studies on PtNPs.
• Analysis of PtNP synthesis routes and their impact on biocompatibility.
• Evaluation of toxicological data and cellular function impairment.

Main Results:

• PtNPs demonstrate significant catalytic activity in reducing intracellular ROS.
• Evidence supports the anti-inflammatory potential of PtNPs.
• Cytotoxicity is linked to synthesis and surface functionalization, not inherent material properties.
• PtNPs' enzymatic activity can target pathological ROS.

Conclusions:

• PtNPs are promising for nanomedicine due to their ROS-scavenging and anti-inflammatory effects.
• Careful control over synthesis and surface modification is crucial for safe and effective application.
• PtNPs hold potential for therapeutic intervention in inflammatory diseases and as diagnostic tools.
