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

Nanoparticle Current Events and Nanoparticle News RSSNew technique sees into tissue at greater depth, resolution
By coupling a kicked-up version of microscopy with miniscule particles of gold, Duke University scientists are now able to peer so deep into living tissue that they can see molecules interacting.
NC State Engineers Discover Nanoparticles Can Break On Through
In a finding that could speed the use of sensors or barcodes at the nanoscale, North Carolina State University engineers have shown that certain types of tiny organic particles, when heated to the proper temperature, bob to the surface of a layer of a thin polymer film and then can reversibly recede below the surface when heated a second time.
Nanoscale silver: No silver lining?
Widespread use of nanoscale silver will challenge regulatory agencies to balance important potential benefits against the possibility of significant environmental risk, highlighting the need to identify research priorities concerning this emerging technology, according to a new report released today by the Project on Emerging Nanotechnologies (PEN).
A new 'Pyrex' nanoparticle
Researchers in Switzerland have developed a new method to fabricate borosilicate glass nanoparticles. Used in microfluidic systems, these "Pyrex"-like nanoparticles are more stable when subjected to temperature fluctuations and harsh chemical environments than currently used nanoparticles made of polymers or silica glass.
Scientists peel away the mystery behind gold's catalytic prowess
Few materials have exercised as much of a hold on the human imagination, or on human history, as has gold.
Nano-sized 'trojan horse' to aid nutrition
Researchers from Monash University have designed a nano-sized "trojan horse" particle to ensure healing antioxidants can be better absorbed by the human body.
University of Pennsylvania Scientists Move Optical Computing Closer to Reality
Scientists at the University of Pennsylvania have theorized a way to increase the speed of pulses of light that bound across chains of tiny metal particles to well past the speed of light by altering the particle shape.
Argonne scientists discover networks of metal nanoparticles are culprits in alloy corrosion
Oxide scales are supposed to protect alloys from extensive corrosion, but scientists at U.S. Department of Energy's Argonne National Laboratory have discovered metal nanoparticle chinks in this armor.
New disease-fighting nanoparticles look like miniature pastries
Ultra-miniature bialy-shaped particles - called nanobialys because they resemble tiny versions of the flat, onion-topped rolls popular in New York City - could soon be carrying medicinal compounds through patients' bloodstreams to tumors or atherosclerotic plaques.
University of Pennsylvania Researchers Demonstrate a Flexible, One-Step Assembly of Nanoscale Structures
Scientists at the University of Pennsylvania have created a one-step, repeatable method for the production of functional nanoscale patterns or motifs with adjustable features, size and shape using a single master "plate."
