Engineering of the high-power laser-induced synthesis of ni-based metal-organic framework: investigation of its optical properties, computational methodology, electrocatalytic performances, and glucose-sensing ability

Abstract

Metal-organic frameworks (MOFs) are porous materials with numerouschemical and structural possibilities. Due to their ease of modification,well-organized structure, and diverse guest molecule chemistry, MOFs areideal platforms for uncovering improved functional material designcharacteristics. Quantitative analysis of glucose is crucial, especially in somefood products, for quality control as well as evaluation of the glucose levelshelps diagnose and treat diabetes. Recent glucose sensing devices have reliedheavily on MOFs and other nanomaterials to enable user-friendly and safenon-invasive sensing methods. Nevertheless, the conventional synthesismethods involve multi-day reactions, cooling, and depressurizationprocesses. This study demonstrates the unprecedented high-powerlaser-induced rapid synthesis (LIRS) of Ni-based MOF nanospheres withinterconnected nano-rods and noncentrosymmetric primitive tricliniccrystalline structure, highlighting their multifunctional usage in sensing andgas sorption applications. Ab initio simulations show excellent agreementwith the experimental physical and gas sorption properties. Furthermore, theNi-MOF-based biosensor accurately measures glucose real-life beveragesamples, yielding promising glucose detection biosensor results with a lowlimit of the detection (LOD) of 13.96 μM and high sensitivity of 120.606 μAmM−1 cm−2.
