Majority of battlefield deaths occur within the first 30 minutes after injury, rapid diagnosis and treatment are crucial for the survival rate of injured soldiers for common injuries such as trauma, shock, brain injury or fatigue. Evgeny Katz of Clarkson University in Potsdam, N.Y., and Joseph Wang of the University of California, San Diego lead a team of researchers who are working on creating enzymes that can measure the biomarkers and provide the logic necessary to make a limited set of diagnoses based on several biological variables using bioelectrodes and biofuel cells developed by them which respond to multiple biochemical signals in a logic way. They are working on creating enzymes that can measure the biomarkers and provide the logic necessary to make a limited set of diagnoses based on several biological variables. The automated sense-and-treat system will continuously monitor a soldier’s sweat, tears or blood for biomarkers that signal common battlefield injuries.In the future they expect to develop implantable devices controlled by physiological signals and responding to the needs of an organism, notably a human and the enzyme-logic sense-and-treat system will revolutionize the monitoring and treatment of injured soldiers and will lead to dramatic improvements in their survival rate.
