Nanomedicine in cancer therapy

Area of Science:

• Oncology
• Nanotechnology
• Biomedical Engineering

Background:

• Conventional and modern cancer therapies lack tumor specificity, leading to significant side effects.
• Nanotechnology offers potential for targeted drug delivery, improving efficacy and reducing toxicity.
• Current nanocarriers often lack hierarchical targeting, limiting their therapeutic potential.

Purpose of the Study:

• To review strategies for designing tumor tissue-, cell-, and organelle-targeted cancer nanomedicines.
• To highlight advancements in hierarchical targeting technologies for cancer therapy.
• To discuss challenges and opportunities for clinical translation of cancer nanomedicines.

Main Methods:

• Review of current and prospective strategies in nanomedicine design.
• Analysis of hierarchical targeting technologies integrating multiple targeting stages.
• Discussion of nano-bio interactions and targeting mechanisms.

Main Results:

• Nanocarriers can achieve improved therapeutic efficacy and reduced toxicity through targeted delivery.
• Hierarchical targeting integrates tissue, cellular, and subcellular localization for maximized outcomes.
• Current nanomedicines face challenges in tumor accumulation, cellular uptake, and subcellular targeting.

Conclusions:

• Hierarchical targeting represents a promising strategy to overcome limitations of current cancer nanomedicines.
• Further development is needed to optimize nanocarrier design for clinical translation.
