Bacteria can’t stick to a new type of nanoscale surface that could prove useful in food processing, medical, and shipping industries.
The technology uses an electrochemical process called anodization to create nanoscale pores that change the electrical charge and surface energy of a metal surface, which in turn exerts a repulsive force on bacterial cells and prevents attachment and biofilm formation.
Whereas a sheet of paper is about 100,000 nanometers thick, these pores can be as small as just 15 nanometers.
When the researchers applied the anodization process to aluminum, it created a nanoporous surface called alumina, which proved effective in preventing surrogates of two well-known pathogens, Escherichia coli O157:H7 and Listeria monocytogenes, from attaching, according to the study in Biofouling.
I’m srry, I had this real cool idea for flux but the world decided today was my day to get extremely sick. Sitting at my desk has been extremely uncomfortable, but I managed enough to doodle this much. Really just a big test on the same texture brush but this time on getting it to blend.
