Prostate cancer is the most common cancer among men except for skin cancer, and the detection at early stages is crucial. In the present work, nanofabricated memristive biosensors are subjected to surface bio-modification targeting at prostate-specific ant ...
We propose the use of a high-refractive index glass microsphere in combination with a conventional fluorescence microscope for imaging sub-cellular organelles and biomolecules. The microsphere is placed on a sample that is immersed in water, collects the n ...
The plasmon enhancement of molecular hyper-Raman scattering, the nonlinear counterpart of Raman scattering, which involves the absorption of two fundamental photons, is investigated with emphasis on low energy molecular vibrations. The two-photon excitatio ...
We present a novel blurring-free stencil lithography patterning technique for high-throughput fabrication of large-scale arrays of nanoaperture optical antennas. The approach relies on dry etching through nanostencils to achieve reproducible and uniform co ...
In this study, we extend imaging and modeling work that was done in Part I of this report for a pure cellulose substrate (filter paper) to more industrially relevant substrates (untreated and pretreated hardwood and switchgrass). Using confocal fluorescenc ...
Bacterial type III secretion systems or injectisomes are multiprotein complexes directly transporting bacterial effector proteins into eukaryotic host cells. To investigate the distribution of injectisomes in the bacterium and the influence of activation o ...
Embodiments of the subject invention relate to a method and apparatus for performing measurements using multiphoton or second harmonic generation (SHG) scattered radiation from a sample including a turbid (scattering) medium includes providing a beam of la ...
Single Molecule Localization Microscopy (SMLM) techniques, such as PhotoActivated Localization Microscopy (PALM) and STochastic Optical Reconstruction Microscopy(STORM), can get around the diffraction limited resolution of conventional fluorescent microsco ...
Super-resolution is a set of techniques used to enhance resolution of image. This work focuses on super resolution used in fluorescent microscopy, ex to image structures in the living cell. In this report we present new method for this task, both in one di ...
A technique that allows direct optical imaging of nanostructures and determines quantitatively geometric nanofeatures beyond the classical diffraction limit by using high-refractive index glass microspheres is introduced. The glass microsphere is put on a ...
