Abstract
Cancer nanomedicines, characterized by submicrometer-sized formulations, aim to optimize the biodistribution of anticancer drugs by minimizing off-target effects, reducing toxicity, enhancing target site accumulation, and improving overall efficacy. Numerous nanomedicines have been developed to improve the effectiveness and safety of traditional anticancer treatments. These include formulations with carbon nanotubes, nanodiamonds, enzyme-responsive nanoparticles for controlled drug release, dendrimers as nanoparticle drug carriers, quantum dot nanocarrier systems for precise drug delivery, solid lipid nanoparticles, and polymeric nanoparticles designed for targeted drug delivery. Additionally, nanotechnology has been explored in cancer treatment through gene therapy. Despite these advances, the complex nature of carrier materials and functional integration presents challenges in preparing these candidates for clinical translation. Nanotechnology, with its unique features at the nanoscale, offers novel possibilities for developing cancer therapies while increasing efficacy and safety. Although only a few nanotherapeutics have obtained clinical approval, exciting uses for nanotechnology are on the horizon. Nanoparticles possess unique transport, biological, optical, magnetic, electrical, and thermal capabilities due to their small size within the light wavelength spectrum. This results in high surface area-to-volume ratios, allowing for the incorporation of various supporting components in addition to active medicinal substances. These properties aid in solubilization, degradation protection, delayed release, immune response evasion, tissue penetration, imaging, targeted distribution, and triggered activation. In summary, the future of nanomedicine holds promise for introducing innovative platforms in cancer treatment. The research presented underscores the potential for nanoparticles to revolutionize anticancer therapies, enhancing the overall therapeutic approach.
