“…The main reason behind the antibacterial properties of graphene is believed to be its physicochemical interaction with bacteria. 63 Recent ndings have proposed three primary mechanisms through which graphene sheets act as antibacterial agents: (1) nano-knives: the sharp edges of graphene cause damage to bacterial cells. (2) Wrapping or entrapment: graphene's dynamic thin lm structure can wrap around or entrap bacterial membranes, leading to their disruption.…”

In this study, for the first time in the literature, synthesis of Au(0) nanoparticles supported by a crosslinked gel structure was performed via enzyme‐mediated reduction of Au(III) ions without using any chemical reductant. In our newly‐developed method, glucose oxidase enzymes immobilized in the crosslinked gelatine structure ensured simultaneous reduction of the Au(III) ions diffused within the gel to Au(0). The Au@Gel obtained was structurally characterised with TEM (Transmission electron microscopy), EDX (Energy dispersive X‐ray analysis) elemental mapping, XPS (X‐Ray photoelectron spectroscopy) and XRD (X‐Ray Diffraction) analyses. The catalytic activity of Au(0) particles with nearly 8 nm size in the Au@Gel was investigated for the reduction of 4‐nitrophenol (4‐NP) as a model compound in the presence of NaBH4 as reducing agent. The activation parameters for the reduction reaction of 4‐nitrophenol in the presence of Au@Gel catalyst were determined as Ea= 30.16 kJmol−, ΔH#= 27.52 kJmol− and ΔS#= −197.45 Jmol−K−. The Au@Gel catalyst system, with good catalytic activity, simultaneously has nearly perfect reusability.
