Development of optical hyperlens for imaging below the diffraction limit.
We report here the design, fabrication and characterization of optical hyperlens that can image sub-diffraction-limited objects in the far field. The hyperlens is based on an artificial anisotropic metamaterial with carefully designed hyperbolic dispersion. We successfully designed and fabricated such a metamaterial hyperlens composed of curved silver/alumina multilayers. Experimental results d...
متن کاملRealization of optical superlens imaging below the diffraction limit
Recently, the concept of superlensing has received considerable attention for its unique ability to produce images below the diffraction limit. The theoretical study has predicted a ‘superlens’ made of materials with negative permittivity and/or permeability, is capable of resolving features much smaller than the working wavelength and a near-perfect image can be obtained through the restoratio...
متن کاملCharacterization of Chicken Thrombocyte Responses to Toll-Like Receptor Ligands
Thrombocytes are the avian equivalent to mammalian platelets. In addition to their hemostatic effects, mammalian platelets rely in part on pattern recognition receptors, such as the Toll-like receptors (TLR), to detect the presence of pathogens and signal the release of certain cytokines. Ligands for TLRs include lipopolysaccharide (LPS), which is bound by TLR4, as well as unmethylated CpG DNA ...
متن کاملFluorescence microscopy below the diffraction limit.
Fluorescence imaging with conventional microscopy has experienced numerous advances in almost every limiting factor from sensitivity to speed. But improved resolution beyond the fundamental limitation of light diffraction has been elusive until recent years. Now, techniques are available that surpass this barrier and improve resolution up to 10 times over that of conventional microscopy. This c...
متن کاملOptical patterning of features with spacing below the far-field diffraction limit using absorbance modulation.
Absorbance modulation is an approach that enables the localization of light to deep sub-wavelength dimensions by the use of photochromic materials. In this article, we demonstrate the application of absorbance modulation on a transparent (quartz) substrate, which enables patterning of isolated lines of width 60 nm for an exposure wavelength of 325 nm. Furthermore, by moving the optical pattern ...
