Development and Evaluation of Novel Drug Delivery Systems for Targeted Cancer Therapy

Thesis Abstract

Abstract
Cancer remains a significant global health challenge, necessitating the development of innovative treatment strategies to improve patient outcomes. The focus of this study is on the development and evaluation of novel drug delivery systems for targeted cancer therapy. In recent years, targeted drug delivery has emerged as a promising approach to enhance the efficacy and reduce the side effects of cancer treatments. This thesis aims to contribute to the field by designing and evaluating new drug delivery systems that can selectively target cancer cells while sparing healthy tissues. The introduction provides an overview of the current challenges in cancer therapy, highlighting the limitations of conventional treatments and the potential of targeted drug delivery systems. The background of the study delves into the existing literature on drug delivery technologies, emphasizing the need for more precise and efficient cancer treatment modalities. The problem statement identifies the gaps in current cancer therapies and sets the stage for the objectives of this study. The primary objective of this research is to develop novel drug delivery systems that can specifically target cancer cells through various mechanisms such as ligand-receptor interactions, nanoparticle-based delivery, and stimuli-responsive drug release. These systems aim to enhance drug accumulation in tumor tissues while minimizing systemic toxicity. The study also addresses the limitations inherent in current drug delivery approaches, including poor bioavailability, non-specific distribution, and drug resistance mechanisms. The methodology chapter outlines the experimental approaches employed in the development and evaluation of the novel drug delivery systems. This includes in vitro cell culture studies to assess the cytotoxicity and cellular uptake of the drug-loaded nanoparticles, as well as in vivo animal models to evaluate the pharmacokinetics and anti-tumor efficacy of the formulations. The research methodology also includes physicochemical characterization techniques to analyze the properties of the drug delivery systems. The discussion of findings chapter presents the results of the experimental studies conducted in this research. It highlights the successful design and characterization of the novel drug delivery systems, demonstrating their ability to target cancer cells selectively and deliver therapeutic payloads effectively. The chapter also discusses the implications of these findings in the context of cancer therapy and the potential for clinical translation. In conclusion, this thesis contributes to the field of cancer therapy by developing and evaluating innovative drug delivery systems for targeted treatment. The study demonstrates the feasibility and efficacy of these systems in improving the therapeutic index of anti-cancer drugs and reducing off-target effects. The findings underscore the importance of personalized medicine approaches in oncology and pave the way for further research in the development of precision cancer treatments.
