Antibacterial surfaces have an enormous economic and social impact on the worldwide
technological fight against diseases. However, bacteria develop resistance and coatings are
often not uniform and not stable in time. The challenge is finding an antibacterial coating that
is biocompatible, cost-effective, not toxic, and spreadable over large and irregular surfaces.
Here we demonstrate an antibacterial cloak by laser printing of graphene oxide hydrogels
mimicking the Cancer Pagurus carapace. We observe up to 90% reduction of bacteria cells …
