Abstract: An ultrasensitive plasmonic near-infrared fluorescent biosensor substrate has been developed for detection of glial fibrillary acidic protein (GFAP) biomarker in blood plasma, an important protein biomarker of traumatic brain injury (TBI). To minimize the interference from blood plasma s le matrix, a near-infrared fluorophore in the first biological transparency window is used in the biosensor. To lify the fluorescence signals, a plasmonic gold nanopyramid array has been coupled to the fluorophore. Finite-difference time-domain simulation reveals that the excitation enhancement is primarily responsible for the fluorescence enhancement owing to the intense local electric field excited on the corners and edges. As a result, this biosensor exhibits a lower limit of detection of 0.6 pg/mL toward detection of GFAP in blood plasma.

Abstract: Cobalt selenide has been proposed to be an effective low‐cost electrocatalyst toward the oxygen evolution reaction (OER) due to its well‐suited electronic configuration. However, pure cobalt selenide has by far still exhibited catalytic activity far below what is expected. Herein, this paper for the first time reports the synthesis of new monoclinic Co 3 Se 4 thin nanowires on cobalt foam (CF) via a facile one‐pot hydrothermal process using selenourea. When used to catalyze the OER in basic solution, the conditioned monolithic self‐supported Co 3 Se 4 /CF electrode shows an exceptionally high catalytic current of 397 mA cm −2 at a low overpotential (η) of 320 mV, a small Tafel slope of 44 mV dec −1 , a turnover frequency of 6.44 × 10 −2 s −1 at η = 320 mV, and excellent electrocatalytic stability at various current densities. Furthermore, an electrolyzer is assembled using two symmetrical Co 3 Se 4 /CF electrodes as anode and cathode, which can deliver 10 and 20 mA cm −2 at low cell voltages of 1.59 and 1.63 V, respectively. More significantly, the electrolyzer can operate at 10 mA cm −2 over 3500 h and at 100 mA cm −2 for at least 2000 h without noticeable degradation, showing extraordinary operational stability.
