Abstract
Nanoparticle-based drug delivery systems have emerged as promising tools in cancer therapy, offering enhanced precision and effectiveness in targeting tumor cells while minimizing damage to healthy tissues. This review provides a comprehensive exploration of the tumor microenvironment, emphasizing its critical role in cancer progression. It highlights the significance of targeted drug delivery in improving treatment outcomes and introduces nanoparticle-based delivery systems as innovative strategies to address these challenges. The first section delves into various types of nanoparticles used for tumor targeting. Liposomes, known for their versatility and biocompatibility, are discussed alongside examples of liposome-based drug delivery systems tailored for tumor-specific applications. Polymeric nanoparticles, employing a range of polymers, offer unique advantages and applications in tumor targeting. Metallic nanoparticles, with distinctive properties, have shown promise in drug delivery systems designed to target tumors effectively.
