Pre-clinical catheter coating technology

InfectoLight

A pH-sensitive colourimetric coating being developed for central venous catheters and peripheral IV cannulas, designed to provide a visible alert of potential bacterial colonisation without instruments.

Visual alert concept Designed for naked-eye monitoring during routine catheter checks, with no reader, instrument, or laboratory workflow.
Use cases Focused on central venous catheters and peripheral IV cannulas, where device surfaces can become routes for microbial colonisation.
Research stage University-originated, pre-clinical technology from Friedrich Schiller University Jena.

The unmet need is not only preventing infection. It is seeing the earliest warning signs sooner.

InfectoLight is positioned as an early warning concept: a passive coating that changes colour in response to microbial activity on catheter surfaces near the insertion site.

Colour change, not extra equipment.

InfectoLight is being developed as a passive catheter coating: a biocompatible polymer matrix with pH-sensitive dyes intended to produce a visible staged signal in response to microbial activity.

Yellow warningLow-level activity is intended to produce an early visible signal.
Blue signalA stronger colour change is intended to indicate a higher level of microbial activity.
