Nanoelectronic materials: fundamentals and applications

Nanoelectronic materials fundamentals applications

Authors: Loutfy H. Madkour

Journal: Springer

Description:

This book presents synthesis techniques for the preparation of low-dimensional nanomaterials including 0D (quantum dots), 1D (nanowires, nanotubes) and 2D (thin films, few layers), as well as their potential applications in nanoelectronic systems. It focuses on the size effects involved in the transition from bulk materials to nanomaterials; the electronic properties of nanoscale devices; and different classes of nanomaterials from microelectronics to nanoelectronics, to molecular electronics. Furthermore, it demonstrates the structural stability, physical, chemical, magnetic, optical, electrical, thermal, electronic and mechanical properties of the nanomaterials. Subsequent chapters address their characterization, fabrication techniques from lab-scale to mass production, and functionality. In turn, the book considers the environmental impact of nanotechnology and novel applications in the mechanical industries, energy harvesting, clean energy, manufacturing materials, electronics, transistors, health and medical therapy. In closing, it addresses the combination of biological systems with nanoelectronics and highlights examples of nanoelectronic–cell interfaces and other advanced medical applications. The book answers the following questions:• What is different at the nanoscale?• What is new about nanoscience?• What are nanomaterials (NMs)?• What are the fundamental issues in nanomaterials?• Where are nanomaterials found?• What nanomaterials exist in nature?• What is the importance of NMs in our lives?• Why so much interest in nanomaterials?• What is at nanoscale in nanomaterials?• What is graphene?• Are pure low-dimensional systems …

Nucleic Acids as Gene Anticancer Drug Delivery Therapy

Nucleic Acids Gene Anticancer Drug Delivery Therapy

Authors: Loutfy H. Madkour

Journal: Copyright © 2019 Elsevier Inc. All rights reserved.

Description:

Nucleic Acids as Gene Anticancer Drug Delivery Therapy highlights the most recent developments in cancer treatment using nucleic acids, nanoparticles and polymer nanoparticles for genomic nanocarriers as drug delivery, including promising opportunities for targeted and combination therapy. The development of a wide spectrum of nanoscale technologies is beginning to change the scientific landscape in terms of disease diagnosis, treatment, and prevention. This book presents the use of nanotechnology for medical applications, focusing on its use for anticancer drug delivery. Various intelligent drug delivery systems such as inorganic nanoparticles and polymer-based drug delivery are discussed. The use of smart drug delivery systems seems to be a promising approach for developing intelligent therapeutic systems for cancer immunotherapies and is discussed in detail along with nucleic acid-targeted drug delivery combination therapy for cancer. Nucleic Acids as Gene Anticancer Drug Delivery Therapy will be a useful reference for pharmaceutical scientists, pharmacologiests, and those involved in nanotechnology and cancer research.

Function of Reactive Oxygen Species (ROS) Inside the Living Organisms and Sources of Oxidants

Reactive Oxygen Species e Living Organisms Sources Oxidants

Authors: Loutfy H Madkour

Journal: Pharma Sci Analytical Res J 2019, 2(2): 180023.

Description:

Reactive oxygen species (ROS) is a generic name given to a variety of molecules and free radicals derived from molecular oxygen. The reduction of oxygen produces relatively stable intermediates. One electron-reduction produces superoxide anion, which is the precursor of most ROS. As most commonly used, ROS in this chapter refer to superoxide, hydrogen peroxide and their derivatives such as the hydroxyl radical. Reactive oxygen species (ROS) were initially recognized as toxic by-products of aerobic metabolism. In recent years, it has become apparent that ROS plays an important signaling role in plants, controlling processes such as growth, development and especially response to biotic and abiotic environmental stimuli. ROS include free radicals such as superoxide anion (O2 ●—), hydroxyl radical (●OH), as well as nonradical molecules like hydrogen peroxide (H2O2), singlet oxygen (1O2), and so forth. Stepwise reduction of molecular oxygen (O2) by high-energy exposure or electron-transfer reactions leads to production of the highly reactive ROS. Reactive oxygen species (ROS) are produced by living organisms as a result of normal cellular metabolism and environmental factors, such as air pollutants or cigarette smoke. ROS are highly reactive molecules and can damage cell structures such as carbohydrates, nucleic acids, lipids, and proteins and alter their functions. Keywords: Reactive oxygen species (ROS); Highly reactive molecules; O2 ●— ; 1O2; ●OH; H2O2; Living organisms
