Quantum dots reviewed — Could these nanoparticles hold the cure to cancer?
September 15, 2006Review of quantum dot technologies for cancer detection and treatment
The worlds of medical and biological research are abuzz with the promises offered by nanoparticles known as semiconductor quantum dots. These Quantum Dots (QDs) have unique optical and electronic properties that make them suitable for breakthrough treatments such as the detection and destruction of cancer cells.
Just released on the nanotechnology website AZoNano, is a comprehensive review of the latest literature and studies into Quantum Dots. The review by Sandeep Kumar Vashist, Rupinder Tewari, Ram Prakash Bajpai, Lalit Mohan Bharadwaj and Roberto Raiteri, researchers from a range of Italian and Indian universities and research organisations, has been released as part of AZoJono*, the open access AZo Journal of Nanotechnology Online.
With a focus on the use of QDs in cancer detection and treatment, the review includes a detailed examination of Quantum Dot advantages, their synthesis, properties and applications, toxic effects, use in imaging and analysis plus Quantum Dot drug delivery systems. The paper also outlines some early success in the detection and treatment of breast cancer.
The paper concludes with a quick look at what the future may hold for Quantum Dots in providing new insights into understanding the pathophysiology of cancer and real time imaging and screening of tumours.
The level of details provided in this valuable review paper could easily make up a chapter in an expensive text book. However, this paper is available to access free of charge in its entirety at http://www.azonano.com/Details.asp?ArticleID=1726

Nanoparticles: From Theory to Application by Günter Schmid (Editor) An introduction to the science of nanoparticles, from fundamental principles to their use in novel applications. As a basis for understanding nanoparticle behavior, the book first outlines the principles of quantum size behavior, nanoparticles architecture, formation of semiconductor and metal nanoparticles. It then goes on to describe the chemical syntheses of nanoparticles with defined characteristics, their structural, electrical and magnetic properties, as well as current methods to monitor these properties. Among others, the following nanoparticle-based applications are discussed: * Single-electron devices * Ultra dense recording media * Bioelectronic devices and sensors * Labeling of proteins, nucleic acids and other biomaterials. ... |

Controlled Synthesis of Nanoparticles in Microheterogeneous Systems (Nanostructure Science and Technology) by Vincenzo Turco Liveri (Author) Because of their structural and dynamical properties, microheterogeneous systems have been employed as solvent and reaction media both to synthesize and stabilize nanoparticles. Following this route, inside their nanometer-sized heterogeneities the nanoparticles of many different substances have been incorporated. The book shows the distinct advantages of this synthetic strategy over that of many other methods. Moreover, it furnishes to the reader a collection of theoretical and experimental facts allowing him to reduce the number of trial and errors necessary to arrive at an optimal synthetic protocol. |

Nanoparticles and Occupational Health (Journal of Nanoparticle Research, 9) by Andrew D. Maynard (Editor), David Y.H. Pui (Editor) Nanotechnology is rapidly invading many aspects of modern society - from science, research and engineering to industrial and commercial applications and, inevitably, to man and his environment. One of the biggest challenges, therefore, is managing environmental, health and safety risks of nanomaterials. Yet, the information necessary to assess their long term effects is scarce. Systematic research into what potentially makes engineered nanomaterials hazardous, how this translates into risk, and how these can be managed will be vital and involves interdisciplinary collaboration. The first International Symposium on Nanotechnology and Occupational Health, in 2004, brought together hygienists, manufacturers, toxicologists, materials scientists, regulators and researchers. It... |

Nanoparticles: Building Blocks for Nanotechnology (Nanostructure Science and Technology) by Vincent Rotello (Author) The diverse structures and properties of nanoparticles make them useful tools for both fundamental studies and pragmatic applications in a range of disciplines. This volume is intended to explore this diversity. The first section covers on formation of nanoparticles, and assembly of these systems into structured systems. The second section focuses on both the fundamental physical properties of nanoparticles and pragmatic applications of these systems in the areas of device and materials fabrication. The book will approach the subject from a chemical standpoint, in contrast to most books which are oriented towards materials science or physics. It will also appeal to materials scientists and physicists who are becoming aware of the contributions that chemists can make here. |

Safety of Nanoparticles: From Manufacturing to Medical Applications (Nanostructure Science and Technology) by Thomas J. Webster (Editor) In spite of the potential use of nanomaterials as tissue engineering devices, implants, biosensors, drug delivery devices, etc., there has yet to be a compilation of the risks associated with the in vivo use of nanomaterials. There are numerous and well-known risks because of the size of nanoparticles. For example, nanoparticles can cross cell membranes and enter the cytoplasm undetected. The aim of this book is to provide one of the first (if not the first) detailed views of how cells and tissues in the body deal with nanoparticles. This is important not only for implantable devices, but also for the manufacturing of nanophase materials when particles can be inhaled or enter the body through the skin. Only by compiling research at the intersection of nanoparticles and... |
