Résumé : |
Studies have shown that the wings of dragonflies and cicadas prevent bacterial growth due to their natural structure. The surfaces of their wings are covered in nanopillars making them look hke a bed of nails. When bacteria come into contact with these surfaces, their cell membranes get ripped apart immediately and they are killed. This inspired researchers from the Institute of Bioengineering and Nanotechnology (IBN) of A*STAR in Singapore to invent an anti-bacterial nano coating for disinfecting frequently touched surfaces, such as door handles, tables and lift buttons. This technology will prove particularly useful in creating bacteria-free surfaces in places like hospitals and clinics, where sterilisalion is important to help control the spread of infections. Their new research was recently published in the journal Small. |
