Abstract(s)
Cancer is a global health challenge, where early detection is crucial to increasing survival rates. Non-invasive, rapid, and affordable diagnostic methods are urgently needed. Immunosensors emerge as promising alternatives to traditional methods such as ELISA, allowing point-of-care (PoC) analyses. This study aims to develop a highly sensitive and selective optical immunosensor for detecting CA 19-9. The results demonstrate successful detection of CA 19-9 over a wide concentration range from 1.77 to 501.87 U mL-1 in 1000-fold diluted human serum in just 10 minutes, with high precision. This device offers rapid, sensitive, and affordable
detection, making it suitable for clinical PoC applications.
