IL6 and Sepsis: Based on this concept, a SERS sandwich-like method combining multisite boronic acid-functionalized magnetic nanomaterials (MBMNPs) and interference-free probes, including 4-mercaptobenzonitrile (4-MP) and ethynylbenzene (EB) reporters conjugated with antibodies as bio-capture and bio-recognition elements, was developed for joint detection of the sepsis biomarkers IL-6 and procalcitonin (PCT) [104].
