Recent advances in smart nanoplatforms for tumor non-interventional embolization therapy

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Oncology

Background:

• Transcatheter arterial embolization (TAE) is a clinical standard for tumor growth inhibition but carries significant risks.
• Nanomaterials offer unique properties for advanced medical applications, including targeted therapies.
• Nanoplatforms are emerging as promising tools for non-interventional tumor embolization therapy.

Purpose of the Study:

• To review recent advances in nanoparticle-based strategies for non-interventional tumor embolization therapy.
• To highlight the benefits and limitations of different nanoparticle approaches.
• To discuss the potential of nanoplatforms in clinical applications for cancer treatment.

Main Methods:

• Review of current literature on nanoparticle applications in tumor embolization.
• Categorization of nanoparticle strategies into three main types based on function and responsiveness.
• Analysis of targeting mechanisms, stimuli-responsive release, and biomimetic properties.

Main Results:

• Identified three key nanoparticle strategies: active targeting/stimuli-responsive thrombin delivery, tumor microenvironment-responsive nanoparticles, and peptide-based nanoparticles.
• Demonstrated potential for enhanced specificity and reduced invasiveness compared to TAE.
• Highlighted the benefits and limitations associated with each nanoparticle type.

Conclusions:

• Nanoparticle-based embolization therapy shows significant potential for safer and more effective tumor treatment.
• Further investigation and development of advanced nanoplatforms are crucial for clinical translation.
• These strategies represent a significant advancement in non-interventional cancer therapies.
