Thesis Abstract

Abstract
Cancer remains a major global health concern, with conventional chemotherapy often resulting in severe side effects due to the lack of specificity in targeting cancer cells. The development of novel drug delivery systems presents a promising approach to enhance the efficacy and reduce the toxicity of cancer therapy. This thesis focuses on the design, development, and evaluation of novel drug delivery systems for targeted cancer therapy. The introduction sets the stage for the study by highlighting the challenges associated with current cancer treatment modalities and the potential benefits of targeted drug delivery systems. The background of the study provides an overview of cancer biology, the principles of drug delivery, and the significance of targeted therapy in improving patient outcomes. The problem statement underscores the need for innovative approaches to overcome the limitations of traditional chemotherapy. The objectives of the study are to design and synthesize novel drug delivery systems, evaluate their efficacy in targeting cancer cells, assess their safety profiles, and explore potential mechanisms of action. The limitations of the study are acknowledged, including constraints related to laboratory resources, time, and the complexity of cancer biology. The scope of the study encompasses in vitro and in vivo experiments using established cancer cell lines and animal models. The significance of the study lies in its potential to advance the field of cancer therapy by providing insights into the development of targeted drug delivery systems that can improve treatment outcomes and patient quality of life. The structure of the thesis is outlined to guide the reader through the various chapters and sections, from the literature review to the research methodology, findings discussion, and conclusion. The literature review critically examines existing research on drug delivery systems for cancer therapy, focusing on both conventional and emerging approaches. Key themes include nanoparticle-based drug delivery, targeted drug conjugates, immunotherapy, and combination therapy strategies. The review highlights the advantages and limitations of different approaches and identifies gaps in current knowledge that the present study aims to address. The research methodology section details the experimental design, materials, and methods used to synthesize and characterize novel drug delivery systems, evaluate their cytotoxicity and targeting efficiency, and investigate their mechanisms of action. Techniques such as nanoparticle formulation, cell culture assays, flow cytometry, and animal studies are employed to achieve the study objectives. The discussion of findings chapter presents the results of the experiments conducted, including the characterization of drug delivery systems, their cellular uptake and cytotoxic effects on cancer cells, and their in vivo efficacy in tumor models. The findings are interpreted in the context of existing literature and implications for future research are discussed. In conclusion, this thesis contributes to the field of cancer therapy by demonstrating the potential of novel drug delivery systems for targeted treatment. The study findings support the hypothesis that targeted drug delivery systems can enhance the therapeutic index of anticancer agents and reduce off-target effects. Recommendations for further research and clinical translation are provided to advance the development of personalized and effective cancer therapies.
