Polyelectrolyte-Stabilised Magnetic-Plasmonic Nanocomposites

Polyelectrolyte-graphene Nanocomposites for Biosensing Applications

Due to their unique structure, the optical and mechanical properties graphene and its derivatives (e.g. graphene oxide, reduced graphene oxide) have captured the attention of a constantly increasing number of scientists with regards to biomolecule sensing. This mini review focuses on one specific type of sensor, that consisting of graphene and polyelectrolytes. Polyelectrolyte-graphene nanocomp...

Effective Optical Properties of Plasmonic Nanocomposites

Plasmonic nanocomposites find many applications, such as nanometric coatings in emerging fields, such as optotronics, photovoltaics or integrated optics. To make use of their ability to affect light propagation in an unprecedented manner, plasmonic nanocomposites should consist of densely packed metallic nanoparticles. This causes a major challenge for their theoretical description, since the r...

Cell surface engineering with polyelectrolyte-stabilised magnetic nanoparticles: a facile approach for fabrication of artificial multicellular tissue-mimicking clusters

Hydrophilic high-luminescent magnetic nanocomposites.

In this study, hydrophilic high-luminescent magnetic nanocomposites (LMNCs) composed of both fluorescent clusters (quantum dots, QDs) and magnetic nanoparticles were synthesized. The nanocomposites exhibited high luminescence and were easily separated in an external magnetic field. The LMNCs were capped with streptavidin (SA), and the SA on the surface of LMNC-SA composites was confirmed to be ...

Self consistent determination of plasmonic resonances in ternary nanocomposites

We have developed a self consistent technique to predict the behavior of plasmon resonances in multi-component systems as a function of wavelength. This approach, based on the tight lower bounds of the Bergman-Milton formulation, is able to predict experimental optical data, including the positions, shifts and shapes of plasmonic peaks in ternary nanocomposites without using any fitting paramet...
