Quantum dots reviewed -- Could these nanoparticles hold the cure to cancer?

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
