Magnetically Guided Bacteria Move Confidently Within Strong Currents, May Soon Deliver Drugs Inside Body

Researchers at Queen’s University in Canada have managed to get a special type of bacteria to swim against a strong current, opening up the possibility of using the organisms as drug delivery vehicles. The team is using magnetotactic bacteria which have magnetic crystals within them and naturally orient themselves with the Eart (Read more...)

Antibacterial Nanoscale Etching of Stainless Steel Surfaces

At Georgia Tech, researchers have developed a way of etching stainless steel surfaces so finely that bacteria that come in contact with them end up being pierced and killed. Interestingly, because of the physiological differences between cell types, mammalian cells don’t seem to be significantly impacted by these surfaces. The electrochemical (Read more...)

Tiny Wireless Neurostimulator Small Enough for Injections

Neurostimulators are becoming popular for treating Parkinson’s, Essential Tremor, pain, and other neurological conditions. They typically involve a battery-powered implant resembling a pacemaker placed on the chest that has electrode leads attached reaching up to another part of the body, often the brain. There are a number of disadvantages w (Read more...)
