Resumo(s)
Biological fluids are the most measured media to monitor metabolites like glucose. Glucose measuring is important since it requires routine track for pa-tients undergoing self-testing, like patients diagnosed with pathologies that re-quire daily control of these metabolites or people who have problems with blood collection like haemophiliacs. It can prove to be painful and stressful collecting samples since most methods are invasive.
The well-being and life quality of these patients can be improved by per-forming non-invasive tests to body fluids at the surface of the skin without ever losing biochemical profiling. Sweat and saliva can be collected more frequently this way, proving less painful and less stressful to the patients.
By combining different biosensing functionalities in a unique membrane, in order to make it multisensorial, and integrate it in a wearable device which can be used on the skin’s surface as a band-aid, it’s possible to perform auto diagnosis keeping in mind a reduced cost policy, portability and ecology.
In this work, cellulose acetate membranes, produced by electrospinning, were used in the construction of electrochemical devices and these were tested for pH and different concentrations of glucose.
