Standard methods of screening men for prostate cancer leave much to be desired, particularly in terms of their inability to have much effect on prostate cancer survival. Now, a team of investigators at the University of Missouri School of Medicine have created a targeted gold nanoparticle that appears to offer a more sensitive and accurate method for detecting early stage prostate cancer. The investigators, led by Raghuraman Kannan and Kattesh Katti, published the results of their studies in the Proceedings of the National Academy of Sciences.

Three-dimensional movies are everywhere these days, and the novelty is poised to become a big-screen mainstay. Now the field of microscopy is getting into the act, too, but the end product is very different from 3-D movies such as Toy Story 3 or Avatar . [More] Recently, hybrid structures of microorganisms with inorganic nanoscale moieties have received great interest owing to their potential in fabricating electronic systems. The electronic properties of metal nanoparticles, as a result of the singleelectron transport of current,[1] make them ideal materials for nanodevices. Concomitantly, the nanostructure of microorganisms such as bacteria,[2] viruses,[3, 4] and yeast[5] are attractive scaffolds for the templating of metal nanoparticles through the interactions of the former with surface charges and the affinity of certain metals for specific biological molecules.[2-7] However, the key challenges in building hybrid devices are 1) to pattern nanostructures without destroying the biological construct of the microorganism and 2) to achieve active integration of a biological response to the electrical transport in a nanoparticle device. Forget surgery. One team of Kansas State University researchers is exploring nanoparticle-induced hyperthermia in the battle against cancer. When it comes to metal catalysts, the platinum standard is, well, platinum! However, at about ,000 an ounce, platinum is more expensive than gold. The high cost of the raw material presents major challenges for the future wide scale use of platinum in fuel cells. Research at the Lawrence Berkeley National Laboratory (Berkeley Lab) suggests that one possible way to meet these challenges is to think small – really small. |
