Cancer remains one of the leading causes of mortality worldwide, requiring more effective and patient-oriented therapeutic approaches. Conventional chemotherapy is often limited by poor selectivity, systemic toxicity, and lack of real-time treatment monitoring. To address these challenges, we have developed an innovative hybrid nanocarrier that combines polymeric matrices with gold nanoparticles to deliver the anticancer drug capecitabine directly to tumor sites. This multifunctional system not only provides localized and controlled drug release but also enables visualization of drug distribution using X-ray-based imaging techniques such as CT. The gold nanoparticles act as both drug carriers and contrast agents due to their high X-ray absorption capacity. Our approach aims to enhance treatment precision, minimize side effects, and allow real-time therapy monitoring, paving the way for truly personalized cancer therapy.
