Abstract
Here, we report a novel approach for non-enzymatic glucose sensing, utilizing a FeCoNiMnCr High Entropy Nano Alloy (HENA) encapsulated within N-doped carbon nanotubes (NCNT). The encapsulation of HENA within NCNT offers multiple advantages such as high sensitivity, low Limit of Detection (LOD), and fast response time. A step forward, the practical viability of the sensor has been demonstrated by detecting glucose in saliva medium. This non-invasive method for monitoring blood sugar levels highlights the potential of HENA@NCNT for wearable or portable glucose monitoring devices. The material also serves as a highly effective electrocatalyst for the oxygen evolution reaction (OER), with performance comparable to state-of-the-art catalyst RuO2. This makes HENA@NCNT a promising candidate for fuel cell applications and other energy storage systems. Density Functional Theory (DFT) analysis provides a deeper understanding of the advantages conferred by NCNT encapsulation. The encapsulation enhances the stability, efficiency, and durability of HENA by optimizing electronic structure and charge transfer processes making it more effective for both glucose sensing and OER
