Highly sensitive non-enzymatic electrochemical glucose biosensor based on PANI: beta 12 Borophene

Abstract

Glucose is one of the main clinical biomarkers which can lead to the micro/macrovascular complications of diabetes. Borophene nanosheets were prepared by ultrasonic sonication. Borophene nanosheets were obtained with beta(12) phase crystalline structure. Then, randomly grown PANI: Borophene nanonetwork was prepared. Glucose sensing performance of Borophene and PANI: Borophene-based non-enzymatic electrochemical biosensors were investigated in detail with in a comparison of the prepared PANI-based biosensor. LOD and LOQ for PANI: beta(12) Borophene-based electrochemical sensor are 0.5 mM and 1.7 mM and for PANI-based electrochemical sensor are 1.2 mM and 3.9 mM, respectively. It can be seen that the prepared PANI: beta(12) Borophene-based electrochemical sensor demonstrates a good improvement over previous reports for glucose sensing using PANI. PANI: Borophene-based biosensor detected 1-12 mM glucose with the sensitivity of 96.93 mu AmM-1 cm(-2) during 1 min cyclic voltammetry measurement. The results reveal that Borophene enhanced the glucose sensing sensitivity of PANI. PANI: Borophene-based biosensor has higher sensitivity and better stability.
