    Metal-organic frameworks (MOFs) are porous materials with numerous chemical and structural possibilities. Due to their ease of modification, well-organized structure, and diverse guest molecule chemistry, MOFs are ideal platforms for uncovering improved functional material design characteristics. Quantitative analysis of glucose is crucial, especially in some food products, for quality control as well as evaluation of the glucose levels helps diagnose and treat diabetes. Recent glucose sensing devices have relied heavily on MOFs and other nanomaterials to enable user-friendly and safe non-invasive sensing methods. Nevertheless, the conventional synthesis methods involve multi-day reactions, cooling, and depressurization processes. This study demonstrates the unprecedented high-power laser-induced rapid synthesis (LIRS) of Ni-based MOF nanospheres with interconnected nano-rods and noncentrosymmetric primitive triclinic crystalline structure, highlighting their multifunctional usage in sensing and gas sorption applications. Ab initio simulations show excellent agreement with the experimental physical and gas sorption properties. Furthermore, the Ni-MOF-based biosensor accurately measures glucose real-life beverage samples, yielding promising glucose detection biosensor results with a low limit of the detection (LOD) of 13.96 µM and high sensitivity of 120.606 µA mM$^{−1}$ cm$^{−2}$.
