Conical diffraction of linearly polarised light in a biaxial crystal produces a beam with a crescent-shaped intensity profile. Rotation of the plane of polarisation produces the unique effect of spatially moving the crescent-shaped beam around a ring. We use this effect to trap microspheres and white blood cells and to position them at any angular position on the ring. Continuous motion around ...

In this paper, an on chip two-dimensional Newton’s ring-like plasmonic sensor is designed for differentiating the chirality of circularly polarized lights (CPLS). The structure consists a circular arc slit and array periodic rectangular nano-grooves that are etched into silver film. When illuminated by CPLS with given chirality, surface plasmon polariton waves generated nano-groove will selecti...

With the advent of nanobiotechnology, there will be an increase in the interaction between engineered nanomaterials and biomolecules. Nanoconjugates with cells, organelles, and intracellular structures containing DNA, RNA, and proteins establish sequences of nano-bio boundaries that depend on several intricate complex biophysicochemical reactions. Given the complexity of these interactions, and...

Bias Temperature Instability (BTI) is a major reliability issue in Nano-scale CMOS circuits. BTI effect results in the threshold voltage increase of MOS devices over time. Given the Process, Voltage, and Temperature (PVT) dependence of BTI effect, and the significant amount of PVT variations in Nano-scale CMOS, we propose a method of combining the effects of PVT variations and the BTI effect fo...

nowadays, the use of innovative nano-technology in the food industry quality control has significantly increased and it is widely employed in numerous fields such as diagnosis of microbial toxin of foods using nano-biosensors, increasing food shelf-life with the help of nano-clay and nano-silver packaging, as well as changing some of the unpleasant organoleptic properties such as taste, color, ...

A surface plasmonic waveguide made of metal–insulator–metal (MIM) capable generating triple Fano resonances is proposed and numerically investigated for multi-biological parameter sensing as well tunable slow light. The up a bus with silver baffle, square split-ring cavity center (SSRCSC), circular ring (CRCSC). Based on the resonances, human blood temperature plasma concentration are measured ...
