Key points from article :
Researchers developed nanoparticles of magnetic liquid metal to fight bacteria.
Once exposed to a low-intensity magnetic field, particles change shape and develop sharp edges.
Can shred bacteria and bacterial biofilm where bacteria live and multiply.
Work against both Gram negative and Gram positive types without harming host cells.
After 90 minutes of exposure both biofilms were destroyed and 99 percent of the bacteria were dead.
Potential to develop as an injectable formula or as a coating for prosthetics.
Research by RMIT University published in ACS Nano.
