Thesis Abstract

Abstract
The development of novel drug delivery systems for targeted cancer therapy has emerged as a promising approach to improve treatment outcomes and reduce systemic toxicities associated with conventional chemotherapy. This thesis presents a comprehensive investigation into the design, development, and evaluation of innovative drug delivery systems tailored for targeted cancer therapy. The research focuses on exploiting nanotechnology-based platforms to enhance the efficacy and specificity of anticancer drugs, ultimately leading to improved patient outcomes. The introduction section provides a detailed overview of the current challenges in cancer therapy, highlighting the limitations of traditional chemotherapy and the need for targeted drug delivery systems. The background of the study discusses the principles of nanotechnology and its applications in cancer treatment, emphasizing the potential benefits of targeted drug delivery systems in improving therapeutic outcomes. The problem statement identifies the gaps in existing cancer treatment approaches and underscores the significance of developing novel drug delivery systems for enhanced efficacy and reduced side effects. The objectives of the study are outlined to investigate the design and development of targeted drug delivery systems using nanotechnology-based approaches, evaluate their efficacy in preclinical models of cancer, and assess their potential for clinical translation. The limitations of the study are acknowledged, including challenges in scaling up nanotechnology-based drug delivery systems for clinical use and potential hurdles in regulatory approval processes. The scope of the study encompasses the design and optimization of nanoparticle-based drug delivery systems, the evaluation of their targeting capabilities in vitro and in vivo, and the assessment of their therapeutic efficacy in animal models of cancer. The significance of the study lies in its potential to revolutionize cancer therapy by improving drug delivery efficiency, enhancing tumor targeting, and reducing off-target effects, thereby enhancing patient outcomes and quality of life. The structure of the thesis is outlined, providing a roadmap for the subsequent chapters that delve into the literature review, research methodology, findings discussion, and conclusion.
