The outstanding properties of graphene arising from its monoatomic thickness, highly conjugated and twin-dimensionality merit attention for plethora of scientific and commercial applications. In this present review, the functionalization of surface chemistry of graphene is investigated to isolate its advantages over non-engineered materials for sensor research and related chemical and electrochemical sensing applications. The review also discuss new perspectives in the employment of these nano-engineered materials in chemical sensing and biosensing applications.

Synthesis And Characterization

An important feature of nanoparticles is the increased ratio of surface area to volume resulting in large percentage of the atoms on the surface, making them very reactive and offers opportunities to manipulate the properties through these surface atoms. For the most efficient use of nanoparticles in various applications, including biology and medicine, it is important to be able to manipulate the surface chemistry. This paper describes the synthesis and characterization of nanoparticles and the various surface engineering techniques that are utilized for optimizing their applications in nanomedicine.

The Impact

The efficient entry of nanotechnology-based pharmaceuticals into target cells is highly desired to reach high therapeutic efficiency while minimizing the side effects. Despite intensive research, the impact of the surface coating on the mechanism of nanoparticle uptake is not sufficiently understood yet. Herein, we present a mechanistic study of cellular internalization pathways of two magnetic iron oxide nanoparticles (MNPs) differing in surface chemistry into A549 cells. The MNP uptake was investigated in the presence of different inhibitors of endocytosis and monitored by spectroscopic and imaging techniques. The results revealed that the route of MNP entry into cells strongly depends on the surface chemistry of the MNPs. While serum bovine albumin-coated MNPs entered the cells via clathrin-mediated endocytosis (CME), caveolin-mediated endocytosis (CavME) or lipid rafts were preferentially involved in the internalization of polyethylene glycol-coated MNPs. Our data indicate that surface engineering can contribute to an enhanced delivery efficiency of nanoparticles.
