• The
• omics
• era has significantly advanced our molecular understanding of cancer, driving the development of personalized medicine.
• Nanoparticle technology presents a novel approach for cancer treatment, integrating targeting, imaging, and therapeutic functions.
• Conventional small molecule therapies have limitations that nanoparticle-based strategies aim to overcome.

Purpose of the Study:

• To review the targeting mechanisms of nanoparticles in the context of cancer therapy.
• To highlight the advantages of nanoparticle technology over traditional treatment methods.
• To discuss the components utilized in active nanoparticle targeting for personalized medicine.

Main Methods:

• Review of existing literature on nanoparticle targeting strategies in cancer.
• Analysis of passive and active targeting mechanisms.
• Discussion of targeting moieties such as small molecules, aptamers, peptides, and antibodies.

Main Results:

• Nanoparticles can be targeted passively (e.g., via the enhanced permeability and retention effect) or actively.
• Active targeting involves incorporating specific molecules on the nanoparticle surface to bind cancer cells.
• These targeting moieties include small molecules, aptamers, peptides, and antibodies, enabling personalized therapy delivery.

Conclusions:

• Nanoparticle technology is a promising platform for personalized cancer medicine.
• Both passive and active targeting mechanisms enhance the efficacy of nanoparticle-based cancer treatments.
• The use of diverse targeting moieties allows for tailored therapeutic strategies for individual patients.
