Being able to determine physiological parameters deep within the distal lung will provide valuable information to clinicians.
.Sensing capabilities are another important aspect of Proteus. To facilitate this, we are developing a series of sensing reporters which are compatible with the fibre bundle system. These reporters are based on the use of fluorescence or Surface Enhanced Raman Spectroscopy (SERS) techniques.
We have developed a range of SERS sensor molecules that can be encapsulated into microspheres. They are then placed onto the end of the fibre in order to directly determine pH and redox potential in the lung.
