Enhanced linear range glucose biosensor based on a prussian blue/glucose oxidase composite with a tailored polyurethane diffusion-limiting membrane

Key Points

• To develop a highly efficient glucose biosensor for improved diabetes monitoring.
• Creation of a multilayer composite structure incorporating prussian blue and glucose oxidase.
• Application of a tailored polyurethane membrane to enhance sensor performance.
• Testing the sensor's response under various glucose concentrations.
• The biosensor demonstrated an enhanced linear range for glucose detection.
• Improved stability and response time compared to previous models.
• Potential for effective continuous glucose monitoring in diabetic care.
