Abstract

Pancreatic cancer has a high mortality rate due to challenges in early detection. This research reports the optimization, structural characterization, and biosensing performance of laserinduced graphene (LIG) electrodes fabricated on paper substrates for CA₁₉-9 detection. Preliminary analyses of urine samples suggest that the paper electrodes show promising results for point-of-care applications.
