Abstract
Polyamines (PAs) are critical biomolecules linked to various diseases, yet their detection remains challenging due to limited electrochemical activity. Enzymatic biosensors enable indirect detection via hydrogen peroxide (H₂O₂), measured using Prussian Blue (PB) electrodes. However, PB’s poor stability in neutral media limits performance. This study investigates the use of polymers (chitosan and PDDA)to enhance the stability and sensitivity of PB-modified screen-printed electrodes for H₂O₂ detection, laying the groundwork for future polyamine biosensors.
