The assumption of a surface CTC in the visible light catalysis was supported by subsequent work on various other types of systems, such as phenolic compounds [11][12], fluoroquinolone antibacterial agents [13], and various colorless aromatic pollutants [14]. Despite the extensive experimental

• electrocatalytic properties. However, it is rarely reported that ECNFs were utilized directly in the design of enzyme-based biosensors. Phenolic compounds, which widely occur in processes of agriculture and industry, often cause severe health problems in human beings and animals [28]. So it is important to develop

• fast and effective methods to detect phenolic compounds. Laccase (benzendiol:oxygen oxidoreductases; EC 1.10.3.2), a multicopper oxidase widely distributed in plant and fungal species, can reduce oxygen directly to water through a four-electron transfer step, and this chemical reaction does not produce

• hydrogen peroxide (H2O2) [29]. Based on this, laccase has been utilized to fabricate a variety of biosensors, including biosensors for phenolic compounds [30]. Nafion, a linear perfluorosulfonate polymer possesses good cation-exchange properties, biocompatibility and film-forming properties and has been
