Nanomaterial Outsmarts Ions
Apr 27, 2014 (SPX)
Ions are an essential tool in chip manufacturing, but these electrically charged atoms can also be used to produce nano-sieves with homogeneously distributed po...
Cloaked DNA nanodevices survive pilot mission
Apr 25, 2014 (SPX)
It's a familiar trope in science fiction: In enemy territory, activate your cloaking device. And real-world viruses use similar tactics to make themselves invis...
Nano shake-up
Apr 22, 2014 (SPX)
Significant advances have been made in chemotherapy over the past decade, but targeting drugs to cancer cells while avoiding healthy tissues continues to be a m...
