What is it about?
Bacterial adhesion and infection is a problem in prosthesis. Controlling bacterial adhesion will help reduce infections and increase success rate of prosthesis. Nanopillars are broadly known to be bactericidal, but their mechanism is not comprehensively studied. We have used extensive microscopic techniques to study he bacteria-nanopillar interaction and explained new insights.

Why is it important?
Knowing how the nature works on killing bacteria on nanopillars will make the way to scientists to engineer bactericidal Nano topographies more effectively and efficiently.
Perspectives
Writing this article was a great pleasure and was a challenging task. As both bacteria and nanopillars are made of hydrocarbons it wasn’t giving sufficient contrast at the interface imaging in TEM. However, we have employed multiple imaging techniques to validate our observations. This approach will confidently enable us to assess the bactericidal mechanism and characteristics on fabricated nanotopographies and compair with the nature. I hope our approach has made researchers to further study the interfacial characteristics in addition to determining bactericidal activity using confocal microscopy alone.
