Abstract:The conventional quantification of Doxorubicin (DXR), a crucial anticancer drug, typically relies on complex and expensive techniques, limiting measurements beyond hospital settings and at different time intervals. Here, a label‐free fluorescence sensor is presented for DXR utilizing Whispering Gallery Mode (WGM) resonators. The resonators are based on fluorescent microparticles coated with a nanometer‐thick polystyrene sulfonate (PSS) layer serving as a synthetic receptor. The sensor demonstrates linear respo… Show more
