Systems, devices, and methods including implantable devices with anti-microbial properties

摘要

Systems, devices, methods, and compositions are described for providing an actively controllable implant configured to, for example, monitor, treat, or prevent microbial growth or adherence to the implant.

主权项

1. An insertable device system, comprising:
a body structure having an outer surface and an inner surface defining one or more fluid-flow passageways; at least one independently addressable and actively controllable anti-microbial nanostructure including a nanofiber of a surface switchable between a zwitterionic state and a non-zwitterionic state and projecting from at least one of the outer surface or the inner surface of the body structure; and circuitry operably coupled to the nanofiber and configured to activate the nanofiber based on at least one signal from a sensor configured to determine the presence of at least one microorganism on at least one of the independently addressable and actively controllable anti-microbial nanostructure of the body structure.
