Thesis Abstract

Abstract
Cancer remains a significant global health challenge, with existing treatment modalities often associated with adverse effects due to non-specific targeting of healthy tissues. The development of novel drug delivery systems for targeted cancer therapy has emerged as a promising approach to enhance drug efficacy while minimizing systemic toxicity. This thesis focuses on the design, development, and evaluation of innovative drug delivery systems tailored for targeted cancer therapy. The introduction provides a comprehensive overview of the current landscape of cancer treatment, highlighting the limitations of conventional therapies and the rationale for the development of targeted drug delivery systems. The background of the study delves into the fundamental principles of drug delivery, emphasizing the importance of achieving site-specific drug release for improved therapeutic outcomes. The problem statement underscores the urgent need for more effective and less toxic cancer treatment strategies, driving the exploration of novel drug delivery platforms. The objectives of the study are outlined to guide the research process, including the design and characterization of targeted drug delivery systems, in vitro and in vivo evaluation of drug release kinetics and therapeutic efficacy, and assessment of biocompatibility and safety profiles. The limitations of the study are acknowledged, such as potential challenges in scaling up production and regulatory hurdles in clinical translation. The scope of the study delineates the specific focus areas and methodologies employed in the research process, providing a roadmap for the investigation. The significance of the study lies in its potential to revolutionize cancer therapy by offering more precise and effective treatment options that can improve patient outcomes and quality of life. The structure of the thesis is detailed to provide a clear framework for the subsequent chapters, encompassing the literature review, research methodology, findings discussion, and conclusion. The literature review synthesizes existing knowledge on drug delivery systems for cancer therapy, highlighting recent advances, challenges, and opportunities for innovation. Key aspects such as targeting ligands, nanocarrier materials, and drug release mechanisms are critically evaluated to inform the design of novel drug delivery systems. The research methodology section outlines the experimental approach taken in the study, including the synthesis and characterization of drug-loaded nanoparticles, in vitro cell culture studies to assess drug release and cytotoxicity, and in vivo animal models for evaluating therapeutic efficacy and biodistribution. Details on analytical techniques, statistical analysis, and ethical considerations are provided to ensure the rigor and reproducibility of the research. The discussion of findings chapter presents a detailed analysis of the experimental results, including drug release profiles, cellular uptake studies, anticancer efficacy data, and safety assessments. The implications of the findings are discussed in the context of existing literature, highlighting the potential of the developed drug delivery systems for clinical translation and future research directions. In conclusion, this thesis contributes to the field of cancer therapy by advancing the development and evaluation of novel drug delivery systems with targeted capabilities. The research outcomes demonstrate the feasibility and efficacy of the proposed drug delivery platforms in enhancing therapeutic outcomes and reducing systemic toxicity. The summary encapsulates the key findings, implications, and future prospects of the study, emphasizing the transformative potential of targeted drug delivery for improving cancer treatment strategies.
