New graphite based rapid sensor chip for real-time theophylline monitoring

Although theophylline (THO) is effective in treating respiratory problems and inflammation, the drug can be toxic if taken above certain limits. This demands accurate and rapid sensing devices that can closely monitor THO levels in patients. Therefore, scientists have now designed a paper-based THO sensor with a response time of 3 seconds. This new sensor is highly selective and sensitive. It has also been successfully tested using whole bovine blood.
