The Technology – brief overview.
The SPaCE NtP swab sensor kit is a cost effective, fast method of assessing wound health. Wounds are swabbed as part of standard care, the swab placed in our patented vesicle gel, left for 30-60 minutes and colour change observed. Bright green colour means that virulence factors associated with SPaCE pathogens were detected. The sensing concept is the same as that used in the SmartWound dressing.
The SPaCE wound swab sensor responds to the four key microbial pathogens found in infected wounds:
The colour change is easily seen by eye (right): Fluorescent green response = SPaCE pathogen positive; dull orange: SPaCE pathogen negative.
