Plasma-Polyplumbagin-Modified Microfiber Probes: A Functional Material Approach to Monitoring Vascular Access Line Contamination

Atmospheric plasma treated carbon fiber filaments (10 micrometer) were used as the base substrate in the design of a probe intended for use within intravascular access devices. The microfiber probe was further functionalized with a polyplumbagin layer through which the line pH could be determined voltammetrically and therein provide the potential for obtaining diagnostic information relating to bacterial colonization of the line. The redox...
