ABSTRACT A rapid, high‐yield laser‐assisted synthesis route with an exceptional production efficiency (≥90%) is introduced for cobalt‐based metal–organic frameworks (Co‐MOFs), producing ordered hybrid structures within an hour that integrate optical, magnetic, and adsorption functionalities. The Co‐MOFs exhibit tunable properties, including a low‐temperature paramagnetic transition confirmed by magnetic measurements and first‐principles calculations. Gas adsorption studies reveal promising performance for N 2 , CH 4 , and CO 2 , combining low energy consumption with cost‐effective gas separation. Structural analysis indicates mesoporosity with high accessibility, supporting selective uptake under practical conditions. Importantly, Co‐MOF‐modified graphite electrodes demonstrate outstanding electrochemical sensing performance for dopamine, achieving a low detection limit (5.5 µ M ), high sensitivity (121 µA mM − 1 cm − 2 ), and excellent reproducibility in human serum. These results underline the multifunctional potential of laser‐synthesized Co‐MOFs as scalable platforms that couple sustainable gas separation with biomedical diagnostics, advancing the development of framework materials for real‐world applications.
