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.
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

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. |

Light Scattering from Polymer Solutions and Nanoparticle Dispersions (Springer Laboratory) by Wolfgang Schärtl (Author) Light scattering is a very powerful method to characterize the structure of polymers and nanoparticles in solution. Recent technical developments have strongly enhanced the possible applications of this technique, overcoming previous limitations like sample turbidity or insufficient experimental time scales. However, despite their importance, these new developments have not yet been presented in a comprehensive form. In addition, and maybe even more important to the broad audience, there lacks a simple-to-read textbook for students and non-experts interested in the basic principles and fundamental techniques of light scattering. As part of the Springer Laboratory series, this book tries not only to provide such a simple-to-read and illustrative textbook about the seemingly very... |
