Branched silver sensor offers more sensitive light-based drug measurements in blood plasma

Medications can save lives, yet for some drugs, the concentration in a patient's bloodstream determines whether a treatment is effective or whether harmful side effects may occur. Researchers at the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, Germany, have developed a sensor surface capable of detecting drugs in blood plasma with high sensitivity while offering significantly greater stability than comparable silver-based surfaces. Their findings have been published in Advanced Science.
