Nanodiamond (ND) based conducting sponges (ND-NS) were prepared through one-step enzymatic polymerization process. A “modular approach” has been demonstrated for the preparation of (ND-NS) with entrapped enzyme (Horseradish peroxidase, HRP) (ND-NS(HRP)). ND-NS was prepared with a mixture of ND, aniline, cross linker and HRP. HRP induces the formation of sponge and simultaneously be entrapped within ND-NS to result ND-NS(HRP). Field emission scanning electron microscope image of ND-NS(HRP) reveals sponge like suprastructure comprising of interconnected nanospheres with numerous openings/pinholes/cavities. The electronic state was determined by UV-visible spectroscopy. The other physico-chemical characteristics of ND-NS(HRP) is carried out. The electrochemical characteristics of ND-NS(HRP) was evaluated and the electron transduction capability between the enzyme and electrode was analyzed. ND-NS(HRP) shows the characteristics of establishing direct electrochemistry and usefulness as a matrix for electrochemical determination of biomolecules.
