Recent advancements in nanoparticles for cancer treatment.

Abstract

Nanotechnology is a significant factor that has assisted researchers in overcoming medications' permeability and retention effects. This article discusses how different nanoparticles, such as metallic nanoparticles, carbon nanotubes (CNTs), and extracellular vesicles (EVs), are transforming cancer treatments and diagnosis. While CNTs provide photothermal qualities that enable synergistic effects when paired with chemotherapy, EVs provide biocompatibility and immune evasion, enabling effective drug transport. Because of their special optical and magnetic characteristics, metallic nanoparticles are essential for imaging and targeted medication administration. When compared to traditional treatments, these nanoparticles improve bioavailability, decrease systemic toxicity, and increase therapeutic efficacy. Despite increased investigations, the number of licensed nano-drugs has remained relatively high. More investigation is required into targeted drug delivery using nanocarriers to minimize the shielding impact of the protein corona, increase permeability and retention effects, and reduce toxicity to improve clinical translation. This study focuses on novel approaches and state-of-the-art cancer therapies using nanoparticles that target different cancer cells. It also emphasized the advantages of nanoparticle-based cancer therapies over conventional ones, their difficulties, and future promises.
