Conventional therapies often affect healthy tissues, leading to significant side effects. To overcome these challenges, researchers are exploring new methodologies that combine advanced drug delivery systems with state-of-the-art imaging technologies to target tumors more effectively. This study aims to investigate a novel approach that integrates smart drug delivery systems with real-time imaging modalities. The goal is to enhance the targeted delivery of therapeutic agents to cancer cells, minimizing damage to healthy tissues while improving the overall efficacy of cancer treatments. Smart drug delivery systems are designed to transport medications directly to tumor sites, enhancing treatment precision. When combined with real-time imaging tools such as MRI, CT, PET, and molecular imaging, these systems offer real-time data on the tumor's location, size, and response to treatment. This allows for immediate adjustments in therapy, ensuring optimal drug delivery and reducing side effects. However, the implementation of this approach also faces challenges, including the need for stringent safety protocols and adherence to regulatory standards. The integration of advanced drug delivery systems with cutting-edge imaging technologies presents a promising approach to cancer therapy. By enabling more precise treatment targeting and reducing adverse effects, this strategy has the potential to significantly improve patient outcomes in the fight against cancer.</p>","PeriodicalId":94352,"journal":{"name":"Recent advances in drug delivery and formulation","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142934347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
