Abstract:
Acute medical diseases demand rapid intervention and treatment, every delay inducing a higher morbidity and an additional risk for the patient. In the field of obstetrics and pediatric medicine, pathogenic species are especially dangerous since they produce infections in pregnant mothers (infections that are usually transmitted to the fetus) or in infants (their body is often small and unable to produce a large quantity of antibodies to fight-off the infection). The golden standard for identification of the infection vector is blood culture, a process which takes up to a few days. Since the infected patient is prone to complications and sepsis, induced by untreated infections, the emergency field needs rapid and accurate sensors for identification of pathogen species. The colorimetric sensors provide a simple, cheap and disposable alternative to conventional detection methods. In this study, we focus on the development of a colorimetric sensor array, based on several organic dyes, for the detection of Candida albicanis (the most common fungal infection in pregnant women) and E-coli (common gastro-intestinal infection in children).
