The efficient detection of charged biomolecules by biosensor with appropriate semiconducting nanomaterials and with optimum device geometry has caught tremendous research interest in the present decade. Here, the performance of various label-free electronic biosensors to detect bio-molecules is investigated by simulation technique. Silicon nanowire sensor, nanosphere sensor and double gate fiel...

BACKGROUND Glucose biosensors comprised of nanomaterials such as carbon nanotubes (CNTs) and metallic nanoparticles offer enhanced electrochemical performance that produces highly sensitive glucose sensing. This article presents a facile biosensor fabrication and biofunctionalization procedure that utilizes CNTs electrochemically decorated with platinum (Pt) nanospheres to sense glucose amperom...

TiO2-Pd/Pt hollow nanosphere (HNS) are prepared via NaCl templates in a one-pot approach.

Spin–orbit interactions of light are ubiquitous in multiple branches nanophotonics, including optical wave localization. In that framework, it is widely accepted circularly polarized beams lead to spin-dependent apparent shifts dipolar targets, commonly referred as mirages. contrast, these mirages vanish when the illumination comes from a spinless beam such linearly wave. Here we show localizat...

The Fano resonance demonstrates excellent performance due to its narrow asymmetrical spectral line shape, and sensitivity structure material parameter changes. Compared conventional resonances, the generated by magnetic dipole is more advantageous because of high absorption low loss. In this study, we propose an Au nanosphere dimer–dielectric–gold film sandwiched that supports mode. And can be ...

objective(s) several antigens, adjuvants and delivery systems have been evaluated for induction of protective immune responses against leishmaniasis, but most of them have been inefficient. in this study, plga nanospheres as antigen delivery system cpg-odn as an immunoadjuvant for increasing the immune responses against autoclaved leishmania major (alm) were prepared and characterized. material...

Besides the multifunctionality, another equally important aspect of nanoparticles is their engineerability to control the geometrical and chemical properties during fabrication. In this work, we exploited this aspect to define asymmetric surface chemistry of an iron oxide nanosphere by controlling the topology of ligand expression on its surface resulting in a particle with two faces, one displ...

Localized surface plasmon resonance (LSPR) is the coherent oscillation of conductive electrons confined in noble metallic nanoparticles excited by electromagnetic radiation, and nanosphere lithography (NSL) is one of the cost-effective methods to fabricate metal nanostructures for LSPR. NSL can be categorized into two major groups: dispersed NSL and closely pack NSL. In recent years, gold nanoc...

Honeycomb structured copper indium sulfide layers are successfully realized via a nanosphere lithography route employing polystyrene array templates and metal xanthates or nanocrystal ink.
