Book Description
This book presents the advances in super-resolution microscopy in physics and biomedical optics for nanoscale imaging. In the last decade, super-resolved fluorescence imaging has opened new horizons in improving the resolution of optical microscopes far beyond the classical diffraction limit, leading to the Nobel Prize in Chemistry in 2014. This book represents the first comprehensive review of a different type of super-resolved microscopy, which does not rely on using fluorescent markers. Such label-free super-resolution microscopy enables potentially even broader applications in life sciences and nanoscale imaging, but is much more challenging and it is based on different physical concepts and approaches. A unique feature of this book is that it combines insights into mechanisms of label-free super-resolution with a vast range of applications from fast imaging of living cells to inorganic nanostructures. This book can be used by researchers in biological and medical physics. Due to its logically organizational structure, it can be also used as a teaching tool in graduate and upper-division undergraduate-level courses devoted to super-resolved microscopy, nanoscale imaging, microscopy instrumentation, and biomedical imaging.

Book Description
Imaging with resolution beyond the diffraction limit has attracted great interest in recent years. In this work, new tools for super resolution optical imaging using plasmonics are developed and demonstrated theoretically and/or experimentally: Localized Plasmonic Structured Illumination Microscopy (LPSIM) and the hyperlens. The LPSIM technique offers a significant improvement in resolution performance over existing structured illumination microscopy (SIM) methods. An array of plasmonic nano-antennas provide dynamically tunable near-field excitations, which result in a finely structured illumination pattern for a given fluorescent object of interest. The illumination pattern feature sizes are limited only by the antenna geometry, and reconstruction from simple far-field images yields deeply subwavelength resolution. In the initial theoretical and experimental demonstrations shown, resolution is improved 3-fold relative to the diffraction limit. LPSIM is attractive among competing tools due to its wide field of view, bio-compatibility, and video-rate speed capability. Imaging applications of the hyperlens are also shown in this work. A spherical, metal-dielectric multilayer geometry is used to numerically demonstrate unprecedented radial resolution at 5 nm scale for both imaging and lithography applications. Accuracy far beyond the diffraction limit in the radial direction indicates potential for three-dimensional imaging and lithography applications. Design optimization with regards to several important hyperlens parameters is explored in detail.

Book Description
Plasmonics, taking advantages of coupling photons to free electrons in metals, enables prominent electromagnetic field enhancements by concentrating light into subwavelength scales, allowing super resolution imaging, enhancement of fluorescence and photothermal heating. In this dissertation, a plasmonic grating platform prepared by nano-imprint lithography was introduced for imagingnanostructures, biological materials, and diagnostics of nanoenergetic systems. First, a glancing angledeposition technique was developed to combine periodic gratings with nano-protrusion for single moleculesuper-resolution imaging for dye-labeled DNA/RNA duplex in wide dye concentrations. The combination of the plasmonic probes and localization microscopy can resolve features as small as 65 nm. Then, the subwavelength nanoparticles with various shapes were studied by different super-resolution approaches. Further, the plasmonic grating microchips facilitate a robust in-situ diagnostic platform for the laser-induced photothermal heating and combustion of aluminum nanoparticles (Al NPs)-fluoropolymer nanoenergetic films. A fluorescence-based temperature sensor with temperature-sensitive dye was developed for dynamic thermal mapping at the nanoscale. The plasmonic grating enables visualization and initialization of localized nano-flames whose temperatures were obtained by two-color pyrometry. Scattering measurements enabled precise identification of individual Al NPs over a large field of view, leading to 3D reconstruction of combustion events

Book Description
Plasmonic nano-objects have shown great potential in enhancing sensing, energy transfer and computing, and there has been much e↵ort to optimize plasmonic systems and exploit their field enhancement properties. Super-resolution imaging with quantum dots (QDs) is a promising method to probe plasmonic near-fields. However, due to the strong coupling between QDs and plasmons, this technique is hindered by the formation of distorted point spread functions (PSFs) and QD mislocalizations. Chapter 4 of this dissertation investigates the coupling between QDs and 'L-shaped' gold nanostructures, and demonstrates both theoretically and experimentally that this strong coupling can induce polarization- / wavelength-dependent changes to the apparent QD emission intensity, polarization and position. From the magnitude and direction of the PSF shift under emission polarization modulation, the coupling strength can be extracted, and the true PSF location can be back-calculated from tabulated theoretical and experimental values. This discovery helps to better apply super-resolution imaging techniques to detect the plasmonic near-fields.Besides using fluorescence intensity as the local-field intensity indicator, photophysical properties of the emitter (e.g. on-time ratio) have shown to be a great candidate as well. Super-resolution fluctuation imaging (SOFI) has great potential in extracting the photophysical properties of emitters with super-resolution. In chapter 5, I discuss an open-source, modular SOFI analysis package we built for both reconstructing super-resolved plasmonic near-fields and engaging the SOFI community with a wide range of applications. Chapter 6 demonstrates how we characterize the photophysical properties of a specific fluorescent protein suitable for SOFI analysis. Our work provides a practical method with higher precision for plasmonic near-field mapping, which benefits many applications like biosensing and optical quantum computing.
