Introduction
Cancer, a leading cause of death globally, presents unique challenges due to its heterogeneity and complex molecular signatures. Conventional treatments like surgery, radiation, and chemotherapy often lack specificity, leading to adverse side effects and treatment failures. Targeted drug delivery, aiming to increase drug concentration at the tumor site, offers a promising solution. Nanomedicine, utilizing nanoparticles (NPs) as drug carriers, has emerged as a key technology in this area. NPs, due to their size and ability to encapsulate drugs, can improve drug solubility, stability, and targeted delivery. However, the heterogeneity of tumors poses challenges in developing effective and personalized treatment plans. Artificial intelligence (AI), with its ability to analyze large datasets and identify patterns, offers a powerful tool to overcome these limitations. This review explores the current progress and challenges of integrating NPs and AI for targeted drug delivery in cancer therapy, emphasizing the need for more research in this crucial area. The study focuses on showcasing how the combined use of NPs and AI can improve cancer treatment by enhancing drug delivery precision, optimizing treatment strategies, and facilitating more accurate diagnoses.
Literature Review
The review utilized the PRISMA methodology and surveyed a wide range of literature from computer science, biomedical, and biotechnology journals and conferences. Databases such as IEEE, SAGE Journals, Springer, Elsevier, MDPI, Frontiers, and the National Library of Medicine's National Centre for Biotechnology Information were consulted. The focus was on publications from the last ten years, excluding preprints. Approximately 100 out of 150 reviewed publications were included, emphasizing recent applications of NPs in drug delivery, challenges in this field, and the potential of AI intervention. While extensive literature exists on drug delivery, drug design, bionanotechnology, and NPs for targeted delivery, studies directly addressing the convergence of NPs and AI in targeted drug delivery were limited. This prompted a narrative review, focusing on the potential of AI integration in the field, especially for addressing existing challenges and identifying research gaps.
