Studies on Graphene-Based Nanomaterials for Biomedical Applications
This thesis presents various applications of graphene-based nanomaterials, especially in biomedicine. Graphene and its derivatives have gained enormous attention from scientists in all fields of study due to many unprecedented properties. The initial scientific attention was focused on the development of transparent flexible electrodes by exploiting two-dimensional graphene film’s extraordinary electrical and physical properties. Recently, given an increasing evidence of dispersed graphene-based nanomaterials’ biocompatibility, researchers have endeavored to employ these materials in other studies relevant to biomedical technologies. In this respect, the thesis provides a comprehensive review on the synthesis, toxicity, and a few of the key biomedical applications in the first chapter. The following chapter discusses the use of a graphene film as a novel catalyst to oxidatively destroy phenols, which are known to be potentially mutagenic and carcinogenic. Finally, and most importantly, the last chapter introduces the therapeutic role of graphene quantum dots, the smallest graphene-based nanomaterials, for Parkinson’s disease. The results are promising for the use of graphene quantum dots as the basis of future clinical drug candidates for neurodegenerative disorders.
Applications of Graphene and Graphene-Oxide based Nanomaterials
Carbon nanomaterials have a unique place in Nanoscience owing to their exceptional electrical, thermal, chemical and mechanical properties and have found application in areas as diverse as composite materials, energy storage and conversion, sensors, drug delivery, field emission devices and nano-scale electronic components. Conjugated carbon nanomaterial covers the areas of carbon nanotubes, fullerenes and graphene. Graphene is the newest of the carbon nanomaterials and promises to be a very active field. Already since its isolation in 2004 it has grabbed the attention of the chemistry, materials and physics communities. It promises to rival carbon nanotubes in terms of properties and potential applications with the number of publications rising from ca. 130 in 2005 to ca. 2,800 in 2010. In this short book Sekhar Ray gives an overview on graphene and graphene-oxide with a strong focus on applications. Structured in three chapters, one on graphene, one on graphene-oxide and one on graphene based nanoparticles his resource describes in each chapter the preparation (including synthesis and functionalization) and material properties before detailing a whole range of applications. Ray finishes each chapter with information on remaining challenges and perspectives. - Written by an expert in the field who, during his last 17 years of research, has published more than 80 peer reviewed articles in recognized international journals - Gives full-chapter overviews on Graphene, Graphene-Oxide, and Graphene based nanoparticles - Focusses on applications

Learn to Use Nanoscale Materials to Design Novel Biomedical Devices and Applications Discover how to take full advantage of nanoscale materials in the design and fabrication of leading-edge biomedical devices. The authors introduce you to a variety of possible clinical applications such as drug delivery, diagnostics, and cancer therapy. In addition, the authors explore the interface between micron and nanoscale materials for the development of applications such as tissue engineering. Finally, they examine the mechanisms of cell interactions with material surfaces through the use of nanotechnology-based material processing and characterization methods. The text's three sections highlight its interdisciplinary approach: * Part One: Nanostructure Fabrication * Part Two: Bio-Nano Interfaces * Part Three: Clinical Applications of Nanostructures Among the key topics covered are nanotechnology in tissue regeneration; biomolecular engineering; receptor-ligand interactions; cell-biomaterial interactions; nanomaterials in diagnostics, drug delivery, and cancer therapy; and nano- and micron-level engineering and fabrication. Throughout the text, clear examples guide you through the chemistry and the processing involved in designing and developing nanoscale materials for biomedical devices. Each chapter begins with an introduction and ends with a conclusion highlighting the key points. In addition, references at the end of the chapter help you expand your research on any individual topic. In summary, this book helps biomedical researchers and engineers understand the physical phenomena that occur at the nanoscale in order to design novel cell-based constructs for a wide range of applications.
