Abstract
Opioids can be detected using a test system with ZnO pillars arranged in an array on a silicon wafer. Silver particles are on a top surface and/or side surface of the ZnO pillars. A sample fluid is applied to the test system. A concentration of an opioid compound in the sample fluid is determined using Surface-Enhanced Raman Spectroscopy of the test system. The sample fluid can be blood or a fluid isolated from blood.
