Capillary-SERS sensor based on aptamer-mediated inhibition of nanozyme catalysis for ultrasensitive detection of homocysteine in serum from hepatocellular carcinoma patients
{{output}}
Early detection and sensitive monitoring of homocysteine (Hcy) in serum are crucial for liver cancer screening. Here, we developed a capillary-based SERS sensor utilizing aptamer capture of Hcy and the highly catalytic properties of nanozymes to achieve ultras... ...
