Abstract:

With the development of flexible electronics, the conductive hybrid films of gold nanoparticles (GNPs) and cellulose which not only enhanced the stability of GNPs, but also improved the usability of hybrid materials, could be used as flexible substrates of sensors. In this paper, the electrochemical availability of tunnelling conductive hybrid films of GNPs and cellulose was mentioned. The hybrid films provided with stable tunnelling conductive properties were used as substrates of electrochemical electrodes to load calmodulin proteins for sensing of calcium cations. The hybrid films with 20 nm GNPs of 46.7% (in weight) exhibited stable electrochemical properties, and showed significant responses to calcium cations after being loaded with CaM proteins. Electrochemical properties of the novel electrodes based on tunnelling conductive hybrid films of GNPs and cellulose were demonstrated and analyzed.
