Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>An ultrasonic nebulizer‐based spray method was developed to fabricate microshpere hybrids of crumpled graphene (CG) loading cobalt oxide (CoO). The as‐prepared CoO/CG microsphere hybrids were used for constructing an enzymeless sensor for glucose detection in alkaline solution. The as‐developed enzymeless glucose sensor exhibited rapid response (less than 3 s), high sensitivity (669.78 µA mM⁻¹ cm⁻²), wide detection range (0.83 µM–8.61 mM), good reproducibility and stability, and low detection limit (0.46 µM) (<italic>S</italic>/<italic>N</italic>=3). Moreover, the detection of glucose in human blood serum samples with the as‐developed sensor agreed well with the results obtained from commercial glucose meters.</p> </abstract>
