n this paper we attempt to present a multilayered structure biosensor. A graphene-based surface plasmon resonance (SPR) biosensor is considered as a structure which offers the enhancement of sensitivity in comparison with ...

In recent times, single layer graphene oxide (GO) has been of intense interest for a broad spectrum of applications. Size and surface charge of GO sheets are two key factors in the most of these fields. These structural ...

Alpha-synuclein (α-Syn) is an abundant protein in the brain with high tendency to convert into toxic aggregated forms that are involved in neurons degeneration in Parkinson's patients (PD). The conversion of α-Syn toward ...

Titanium nitride-carbon nanocomposites have been synthesized by the reaction of TiCl4 and NaN3 in supercritical benzene medium that also serves as a carbon source. The as-prepared precursor has been subjected to different ...

Er3+-Yb3+ co-doped titanium dioxide upconversion nanoparticles were synthesized by Sol-gel method. White upconversion emissions were observed after excitation of nanoparticles with 980 nm Near-Infrared laser diode. ...

For a successful bladder tissue repair and reconstruction, fabrication of scaffolds with proper biochemical and biomechanical characteristics is necessary. Decellularized bladder tissue has been proposed in previous studies ...

DNA nanotechnology is a purist's approach to biomolecular engineering. The field aims to create molecular structures and devices through the exclusive use of DNA as an engineering material. On the other hand, DNA Spintronics ...

In this work, hybrid of silica nanoparticles (NPs) with sulfonated copolymer has been prepared in order to improve the copolymer properties for enhanced oil recovery (EOR).  Some tests are done to find the effectiveness ...

Nanofibrous composite scaffolds based on Tecophilic (TP) and gelatin (gel) were electrospun and further modification of their surfaces was performed by adsorption of gelatin or fibronectin biomolecules. The ability of ...
