What is it about?
Dr. Akiko Ogawa and her colleagues found how nickel, molybdenum and tungsten nano-powders could behave to form biofilm formation. They utilized silane compounds as the substrate for dispersion of nanopowders. That seems to be good for them to achieve the antifouling purposes since the silane compound has lots of nano crevices called free-volume. The nanopowders in the free volume dissolve to be ions gradually and the ionized heavy metals seem to work against biofilm formation. They also showed that staining by crystal violet would be the most useful industrial tools for biofilm formation.

Why is it important?
#1: They could show the effectiveness of silane compound coating for the composite coating. #2: The could show the anti-fouling effect of nickel, tungsten, and molybdenum. #3: Particularly, this is the first report in the world for the effect of tungsten. #4: They could show the biosafety for those heavy metals simultaneously. #5; The evaluation ways of biofilms and biosafety are unique and useful.
Perspectives
Their way will be utilized for all other nanopowders and also for other coatings. The combination of biofilm evaluation and biosafety would be unique and useful for the future.
