  Combining protein-shelled platinum nanoparticles with graphene to build a bionanohybrid capacitor.

  , ACS Nano, Vol: 8, Pages: 12120-12129

  The electronic properties of biomolecules and their hybrids with inorganic materials can be utilized for the fabrication of nanoelectronic devices. Here, we report the charge transport behavior of protein-shelled inorganic nanoparticles combined with graphene and demonstrate their possible application as a bionanohybrid capacitor. The conductivity of PepA, a bacterial aminopeptidase used as a protein shell (PS), and the platinum nanoparticles (PtNPs) encapsulated by PepA was measured using a field effect transistor (FET) and a graphene-based FET (GFET). Furthermore, we confirmed that the electronic properties of PepA-PtNPs were controlled by varying the size of the PtNPs. The use of two poly(methyl methacrylate) (PMMA)-coated graphene layers separated by PepA-PtNPs enabled us to build a bionanohybrid capacitor with tunable properties. The combination of bioinorganic nanohybrids with graphene is regarded as the cornerstone for developing flexible and biocompatible bionanoelectronic devices that can be integrated into bioelectric circuits for biomedical purposes.

  Conditioning of graphene surface by CO<inf>2</inf>cluster jet

  , RSC Advances, Vol: 4, Pages: 41922-41926

  © the Partner Organisations 2014. The reduction of resistance and surface roughness obtained by CO2cluster jet were up to 81% and 42.3% compared with pristine graphene. The shifts in Raman spectra also implied chemical doping and "mono-layerization". Thus, CO2cluster jet has the potential for planarization, cleaning and flattening of the graphene. This journal is
