The selective and rapid detection of FKBP12 is crucial due to its involvement in immunosuppression, neurodegenerative and oncological diseases, and some fundamental cellular processes. A low-cost point-of-care test (POCT) based on a simple setup, combined with plasmonic sensor chips for ultrasensitive detection of FKBP12, is developed. The sensing principle exploits pollen-based natural nanostructures covered by gold nanofilms and functionalized with synthetic GPS-SH1 receptors. The experimental results demonstrated ultrahigh performance due to…
