In the present work, chemically synthesized graphene nanosheets were used as electrode materials and their electrochemical properties systematically characterized. The surface morphologies of evaluated using Raman spectroscopy transmission electron microscopy. results obtained compared with that single-walled carbon nanotubes (SWCNTs). Results indicated possesses greater sp2 character than SWCNTs. Using a four-point probe technique, we found conductivity particles to be 64 mS cm−1, which is...
In this work, we report the enhanced performance of polypyrrole−graphene−glucose oxidase based enzymatic biosensors employed for in vitro electrochemical glucose detection. Initially, graphene nanosheets were chemically synthesized and surface morphologies characterized by several physical methods. Following this, covalently conjugated to an enzyme model (GOD). The presence various reactive functionalities such as ketonic, quinonic, carboxylic functional groups on edge plane easily binds...
Combining chemotherapy with gene therapy has been one of the most promising strategies for treatment cancer. Noninvasive MRI superparamagnetic iron oxide (SPIO) as a contrast agent is effective techniques evaluating antitumor therapy. However, constructing single system that can deliver efficiently gene, drug and SPIO to cancer site remains challenge. Herein, we report chitosan functionalized magnetic graphene (CMG) nanoparticle platform simultaneous gene/drug delivery tumor. The phantom ex...
A single material that can perform water oxidation and oxygen reduction reactions (ORR), also called bifunctional catalyst, represents a novel concept emerged from recent materials research has led to applications in new‐generation energy‐storage systems, such as regenerative fuel cells. Here, metal/metal‐oxide free, doped graphene derived rhombohedral boron carbide (B 4 C) is demonstrated be an effective catalyst for the first time. B C, one of hardest nature next diamond cubic nitride,...
Transition metal dichalgogenides such as MoS2 have recently emerged hot two-dimensional (2D) materials due to their superior electronic and catalytic properties. Recently, we reported the usefulness of nanosheets toward electrochemical detection neurotransmitters glucose (Narayanan et al 2014 Nanotechnology 25 335702). Furthermore, there are reports available in literature that demonstrate for biosensing energy storage applications (Zhu 2013 J. Am. Chem. Soc. 135 5998–6001; Pumera Loo Trends...
Poly(ethylene oxide) (PEO)-based composite polymer electrolytes (CPEs) containing the amine-functionalized, zirconium-based metal-organic framework @silica (UiO-66-NH2@SiO2) and lithium, LiN(CF3SO2)2 salt (LiTFSI) are prepared using a simple hot press method.

Graphene, with its exceptional mechanical, thermal, electrical, optical, and electronic properties may exist as single-, few-, or multilayered thin sheets. Though the number of layers affect conductivity, role toward enzyme immobilization enzymatic biosensing applications is unknown. Herein, we report electrochemical performance electrodes graphene comprising varying immobilized glucose oxidase for detection model analyte glucose. It interesting to note that these different-layered exhibit...
The laminated structure of graphene oxide (GO) confers unique interactions with water molecules which may be utilised in a range applications that require materials tuneable hygroscopic properties. Precise roles the expandable interlayer spacing and functional groups GO laminates are not fully understood till date.
