Water filters made with copper could remove bacteria at lower cost (Journal of Applied Physics)

Porous ceramic water filters are often coated with colloidal silver, which prevents the growth of microbes trapped in the micro- and nano-scale pores of the filter. Other metals such as copper and zinc have also been shown to exhibit anti-microbial activity. Princeton University's Wole Soboyejo and colleagues used atomic force microscopy (AFM) measurements to study … Continue reading Water filters made with copper could remove bacteria at lower cost (Journal of Applied Physics)
