Active targeting schemes for nanoparticle systems in cancer therapeutics

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Oncology

Background:

• Cancer remains a leading cause of mortality worldwide, necessitating advanced therapeutic strategies.
• Conventional cancer treatments often lack specificity, leading to off-target side effects.
• Nanoparticle systems offer a promising platform for targeted cancer therapy and diagnostics.

Purpose of the Study:

• To review and categorize current major cancer targets for nanoparticle systems.
• To provide insight into the future direction of nanoparticle-based cancer targeting.
• To consolidate information on various targeting strategies for enhanced drug delivery and imaging.

Main Methods:

• Literature review of nanoparticle systems and their targeting strategies in cancer research.
• Categorization of targeting approaches into three main themes: angiogenesis-associated, cell proliferation markers, and tumor cell targeting.
• Analysis of reported nanoparticle systems and their efficacy in preclinical and clinical studies.

Main Results:

• Identified angiogenesis, uncontrolled cell proliferation markers, and tumor cell surface markers as key targets.
• Detailed various nanoparticle-based strategies for each targeting category.
• Highlighted the potential of these targeted approaches to improve therapeutic outcomes and diagnostic accuracy.

Conclusions:

• Nanoparticle-mediated targeted delivery holds immense potential to transform cancer treatment paradigms.
• Further research and development in nanoparticle targeting are crucial for clinical translation.
• Targeted strategies promise more effective and less toxic cancer therapies.
