Silicon Carbide Nanoparticles Fibrous Membrane for Implantable Glucose Sensors

Advantages

• Easy to fabricate, cost-effective, energy-efficient, and adaptable for detecting diverse biochemical reactions through suitable material choice and surface functionalization.
• Delivers low-noise, high-gain, linear, and stable performance at significantly lower power than previous state-of-the-art potentiostats.
• High sensor durability with 11% performance change sustained over 50 days.
• Highly sensitive, capable of measuring electrochemical currents from 2 µA to 200 µA, with a sensitivity of 30.75 µA/mM·cm² and a low detection limit of 0.56 µM glucose.

Summary

Glucose sensors are used to measure the glucose concentration of a blood in a patient and are an important part of managing diabetes mellitus. This continuous glucose monitoring system needs to be power efficient, compact, portable, sensitive, and have a linear response for targeted levels. This method represents an integrated system with a CMOS based low-power, low-noise chronoamperometric potentiostat circuit and SiCNPs-ENFM based glucose sensor on a single chip. The sensing unit can detect micro amps of electrochemical current from the SiCNPs-ENFM glucose sensor with better sensitivity, limit of detection, fast response time and durability, providing the base for future wearable and portable biosensors.
