The unprecedented medical achievements of the last century have dramatically improved
our quality of life. Today, the high cost of many healthcare approaches challenges their long …

Remarkable progress has been made in the fabrication and characterization of optical
antennas that are integrated with optoelectronic devices. Herein, we describe the …

We present spatial mapping of optical force generated near the hot spot of a metal–dielectric–
metal bowtie nanoantenna at a wavelength of 1550 nm. Maxwell's stress tensor method has …

Chemical sensors and biosensors are advantageous analytical tools which are cost
effective, portable and exhibits sensitivity and selectivity towards many target analytes …

Coupling of a far-field optical mode to electronic states of a quantum absorber or emitter is a
crucial process in many applications, including infrared sensors, single molecule …

Silicon nanowire optical rectangular waveguide (SNORW)-based biosensor is proposed for
the first time to detect deoxyribonucleic acid (DNA) hybridization. It works on the principle of …

Nano-fabrication technologies are usually associated with complication, high cost, and
limited area of coverage. However, advances in optics and nanophotonics constantly …

Electrochemiluminescence (ECL) or electrogenerated luminescence continues to develop
as an effective electroanalytical tool ever since its introduction by Tokel and Bard. 1 …

Fabrication of nanostructures for applications such as plasmonics and metamaterials are
typically accompanied by a slow production and limited area due to the required sub-micron …

We use a finite-difference time-domain (FDTD) approach to describe and control light-
induced charge dynamics via two constructs consisting of nanoscale silver cylinders. The …
