Development of Novel Drug Delivery Systems for Targeted Cancer Therapy

Thesis Abstract

Abstract
Cancer remains a formidable challenge in modern medicine, necessitating continuous research efforts to develop more effective treatment strategies. In this context, the development of novel drug delivery systems for targeted cancer therapy has emerged as a promising approach to enhance the efficacy and reduce the side effects of anticancer drugs. This thesis focuses on exploring the design, development, and evaluation of advanced 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 chemotherapy and the need for more targeted approaches. The background of the study delves into the principles of targeted drug delivery, emphasizing the advantages of site-specific drug release in improving treatment outcomes. The problem statement identifies the gaps in existing drug delivery systems and underscores the importance of developing novel approaches to address these challenges. The objectives of the study are outlined to guide the research process, including the design and synthesis of targeted drug delivery systems, in vitro and in vivo evaluation of their efficacy, and comparison with conventional chemotherapy. The limitations of the study are acknowledged, such as the complexity of translating preclinical findings to clinical applications and the need for further optimization of the delivery systems. The scope of the study encompasses the design and evaluation of various types of drug delivery systems, including nanoparticles, liposomes, micelles, and polymer-based carriers, for targeted delivery of anticancer agents. The significance of the study lies in its potential to contribute to the development of more effective and less toxic cancer therapies, ultimately improving patient outcomes and quality of life. The structure of the thesis is presented to provide a roadmap for the reader, outlining the organization of chapters and key sections. Definitions of key terms are provided to clarify the terminology used throughout the thesis and ensure a common understanding of the concepts discussed. The literature review chapter critically evaluates existing research on targeted drug delivery systems for cancer therapy, highlighting the latest advances, challenges, and opportunities in the field.
