Abstract
Throughout the world, people are seeking medical treatment for numerous chronic illnesses and symptoms concurrently. Because of this trend, people are receiving a wide range of medications to help deal with their illnesses. These medications are often administered through the use of intravenous pumps enabling direct injection into the bloodstream. Similar tubing presents an opportunity for label-free identification and quantification of compounds that are both adminsitered to and excreted from the patient. We demonstrate a rigid surface-enhanced Raman scattering (SERS) sensor made up of a densely packed two-dimensional array of metal nanodomes constructed on a plastic film. The sensor is used to detect commonly used dedications in varying concentrations. Finally, we display a flexible SERS sensor molded to intravenous tubing, capable of detecting metabolites and medications at low concentrations.
