Subdiffraction scattered light imaging of gold nanoparticles using structured illumination.
A reflective light-scattering (RLS) microscope with structured illumination (SI) provides subdiffraction resolution and improves the image quality of gold nanoparticles in biological systems. The three-dimensional (3D)-structured pattern is rapidly and precisely controlled with a spatial light modulator and scrambled at the conjugate image plane to increase spatial incoherence. The reconstructe...
متن کاملSubdiffraction multicolor imaging of the nuclear periphery with 3D structured illumination microscopy.
Fluorescence light microscopy allows multicolor visualization of cellular components with high specificity, but its utility has until recently been constrained by the intrinsic limit of spatial resolution. We applied three-dimensional structured illumination microscopy (3D-SIM) to circumvent this limit and to study the mammalian nucleus. By simultaneously imaging chromatin, nuclear lamina, and ...
متن کاملApplications of gold nanoparticles for medical imaging
Background & Aim: Molecular imaging enables us to non-invasively visualize tissue microstructures and lesion characterization, allowing accurate diagnosis of diseases at early stages. A successful molecular imaging requires a nontoxic contrast agent with high sensitivity. Nowadays, a wide range of nanoparticles have been developed as contrast agents for medical imaging modalities. Here, we revi...
متن کاملPushing the boundaries of digital imaging using Structured Illumination
The principle underlying SI-OSR is the formation of Moiré fringes that result when two patterns such as those shown in Fig.[1]-row1, superimpose multiplicatively. The patterns correspond to the unresolved spatial detail in the scene, and the Structured Illumination. Their product produces fringes at spatial frequencies that are significantly lower than those of the underlying patterns, and pote...
متن کاملSynthesis and characterization of surface-enhanced Raman-scattered gold nanoparticles
In this paper, we report a simple, rapid, and robust method to synthesize surface-enhanced Raman-scattered gold nanoparticles (GNPs) based on green chemistry. Vitis vinifera L. extract was used to synthesize noncytotoxic Raman-active GNPs. These GNPs were characterized by ultraviolet-visible spectroscopy, dynamic light-scattering, Fourier-transform infrared (FTIR), transmission electron microsc...
