Cold Plasma Made Useful to Sterilize Medical Equipment

Cold plasma is a popular topic of research at Purdue University, including as a potential tool for killing cancer cells. It’s cold in the sense that only the electrons within the material are heated up to thousands of degrees, while the rest of the gaseous substance remains near room temperature. Now researchers at Purdue University … Continue reading

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. This may point to interesting applications … Continue reading
