Introduction: This article investigates the use of nanoparticles and their types in the transfer of drugs and genes for diagnosing and treating various diseases.
Methods: A review study was conducted by searching PubMed, Ovid, Google Scholar, and Web of Science databases. Two thousand original and review articles in English with full text were selected through direct content analysis, and one hundred articles were studied and reviewed.
Results: The findings indicate that nanoparticles can facilitate gene and drug transfer, expedite tumor diagnosis, and enable targeted drug delivery with fewer side effects. The use of various nanosystems is beneficial for improving disease processes, accelerating diagnosis, reducing drug toxicity, and enhancing treatment efficacy for cancers and other diseases.
Conclusion: Advancements in nanotechnology contribute to more precise, targeted treatments and quicker diagnosis of various diseases.
