... potential of hybrid nanofibers in biomedical applications was further examined by biological assessment. As shown in Fig. 4, TiN NPs-decorated nanofibers demonstrated good biocompatibility with increased metabolic activity on day 10 and the highest increase of dsDNA content on day 15. The obtained results evidence that novel hybrid matrices based on PCL nanofibers and TiN NPs can serve as excellent candidates for tissue engineering, drug delivery agents and ...

We present an uncooled high-sensitivity bolometric terahertz detector by incorporating plasmonic absorbers and transducer beams made of phase changing materials. We present a comprehensive design parameter analysis of the bolometer device—from electromagnetic absorption to thermal and mechanical analysis. Our design integrates plasmonic absorber an...
We demonstrate a non-contact optical magnetic field sensor that is based on actuation of a metamaterial-microcavity by the magnetic Lorentz force. Magnetic field is transduced to a change of the sensor’s reflectivity. The microscale proof-of-concept metamaterial magnetometer can be read from a distance and offers 60 micrometer spatial, about 10 mic...
The possibility of creating and manipulating nanostructured materials encouraged the exploration of new strategies to control electromagnetic properties. Among the most intriguing nanostructures are those that respond differently to helical polarization, i.e., exhibit chirality. Here, we present a simple structure based on crossed elongated bars wh...
The strong coupling between photons and matter excitations such as excitons, phonons, and magnons is of central importance in the study of light-matter interactions. Bridging the flying and stationary quantum states, the strong light-matter coupling enables the coherent transmission, storage, and processing of quantum information, which is essentia...
For a quantum Internet, one needs reliable sources of entangled particles that are compatible with measurement techniques enabling time-dependent, quantum error correction. Ideally, they will be operable at room temperature with a manageable decoherence versus generation time. To accomplish this, we theoretically establish a scalable, plasmonically...

... A previous study has established the improvement of the properties of polymer nanofibers by coating them with TiN nanostructures. [104] Kattan and Kabashin reported the prospect of generating polymer nanofibers coated with ligandfree plasmonic TiN and Au NPs via the co-electrospinning of different types of polymeric materials (polycaprolactone (PCL)), (chitosan(PEO)) concurrently with TiN and Au NPs which were produced femtosecond laser ablation in liquid ambient techniques. [104] Scanning Electron Microscopy image of the chitosan-based nanofibers decorated by lasersynthesized Au NPs reveals an appropriate uniform attachment of the Au NPs via electrostatic interaction ( Figure 12a). ...

... Moreover, a slight reduction of the fiber diameter was observed when compared to the electrospun nanofibers with no NPs. This was attributed to the influence of the [104] physicochemical features of the NPs electrospinning route. The average particle diameter of the nanofibers was seen to be 190 nm. ...

Titanium nitride, a substitute plasmonic material to gold with exceptional features is a favorable photo-absorbing agent for photothermal therapy (PTT) based on the spectral match of their plasmon resonance band and the biological transparency window as well as good biocompatibility. Nevertheless, a review on its synthesis and possible utilization in photothermal cancer therapy has never been explored. This review presents the synthetic routes of titanium nitrides (TiN) nanoparticles (NPs) and their performance in photothermal cancer therapy. The synthetic techniques that were looked into are solvothermal, hydrothermal, sol-gel, laser ablation, chemical vapor deposition and non-thermal plasma techniques. This study has established the extraordinary prospect of plasmonic TiN NPs in the treatment of cancer via photothermal therapy.
