Abstract
electrochemically roughened gold sensor surfaces; (iii) fit for handheld SERS detection with miniaturized equipment footprint. We evaluated the analytical performance of the nanophotonic immunoarray sensor and successfully demonstrated quantitative sPD-L1 detection in a cohort of contrived human plasma samples.
