Scientists at Northwestern University have developed a powerful new method for detecting infectious diseases, including those associated with many bioterrorism and warfare threats such as anthrax, tularemia, smallpox and HIV.
A research team led by Chad A. Mirkin, director of Northwesterns Institute for Nanotechnology, has invented a technique for creating thousands of DNA detection probes made of gold nanoparticles with individual molecules attached. Much like human fingerprints, these molecules act as unique signals for the presence of different biological agents. The new detection method, for instance, can easily distinguish smallpoxs distinct "fingerprint" from that of HIV.
"By providing a near infinite number of signals, this advance allows researchers to quickly and accurately screen a sample for an extraordinarily large number of diseases simultaneously," said Mirkin, also George B. Rathmann Professor of Chemistry.

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
