A surrounding electromagnetic environment can engineer spontaneous emissions from quantum emitters through the Purcell effect. For instance, a plasmonic antenna efficiently confine an field and enhance fluorescent process. In this study, we demonstrate that photonic microcavity modulate plasmon-enhanced fluorescence by engineering local environment. Consequently, constructed emitter (PE-emitter...

in this paper, surface roughness of ht29 cancerous is determined using topography images obtained by atimic force microscopy (afm). the mean radiuses of cell and substrate surface asperities are determined, based on results of conducted roughness analysis and rabinovich roughness theory. these values have been applied in the equations of rough particle nanomanipulation dynamic model and the amo...

Optical tweezers have emerged as a powerful tool for micro and nanomanipulation. Using optical tweezers to perform automated assembly requires on-line monitoring of components in the assembly workspace. This paper presents algorithms for estimating positions and orientations of microscale and nanoscale components in the 3-Dimensional assembly workspace. Algorithms presented in this paper use im...

High-index dielectrics have recently been regarded as promising building blocks in nanophotonics owing to optical electric and magnetic Mie resonances. In particular, silicon is gaining great interest the backbone of modern technology. Here, dimer nanocavities with different sizes nanospheres were constructed using a probe nanomanipulation method interacted few-layered R6G membrane investigate ...

Molybdenum trioxide shows many attractive properties, such as a wide electronic band gap and high relative permittivity. Monolayers of this material are particularly important, they offer new avenues in optoelectronic devices, e.g., to alter the properties graphene electrodes. Nanoscale electrical characterization is essential for potential applications monolayer molybdenum trioxide. We present...

A large portion of the human genome is transcribed but not translated. In this post genomic era, regulatory functions of RNA have been shown to be increasingly important. As RNA function often depends on its ability to adopt alternative structures, it is difficult to predict RNA three-dimensional structures directly from sequence. Single-molecule approaches show potentials to solve the problem ...
