Download or read book Surface Functionalization for Enhanced Fluorescence Detection Surface Plasmon Resonance Imaging and Microscopy written by Jennifer Betsy Fasoli and published by . This book was released on 2015 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work presents several high throughput imaging and analysis techniques performed by fluorescence detection and surface plasmon resonance biosensing. The microarray fabrication methods introduced in this thesis, as well as the DNA functionalization on planar and nanoparticle surfaces, enable and facilitate the real-time study of adsorption events via DNA- DNA hybridization and protein-DNA interaction. Silica deposited on polyolefin film serves as the base for the development of DNA microarray. Fabrication process involves poly(L-glutamic acid) monolayer to react with amine functional groups functionalized on both the silica surface and the probe DNA strands. Covalently surface-bound probes then hybridize with fluorophore-labeled target DNA. Shrinking the microarray with heat significantly enhances the sensitivity of detection via fluorescence signal amplification. Polydopamine, a biomimetic polymer, easily and rapidly grows an adhesive layer to link amine-terminated, single-stranded DNA to gold surface. Self-polymerization of polydopamine simply requires mild reagents and reaction condition. The microarray formed with polydopamine attachment technique reserves its stability and specificity to detect DNA and protein targets by surface plasmon resonance imaging. This one-step microarray fabrication approach, when coupled with signal amplification from DNA-modified gold nanoparticles, empowers the detection limit capable of seeing down to 10 pM target concentration. Electrochemical deposition of polydopamine demonstrates strong control over film localization and thickness. This meticulous polymerization on gold surface at the microscale proves the high toposelectivity of this deposition technique. Amine-modified DNA bound on this polydopamine thin flim hybridizes with fluorophore-tagged DNA to generate fluorescent DNA micropatterns. This electordeposition also forms DNA microarrays used in surface plasmon resonance imaging for DNA-DNA hybridization and DNA-coated gold nanoparticle adsorption measurements. A 814 nm, near-infrared surface plasmon resonance microscope exemplifies a novel, objective-coupled sensing and imaging system at single-nanoparticle scale. This microscope visualizes individual binding occurrence of gold nanoparticles and polystyrene beads. Adsorption analysis presents the calculated surface plasmon resonance signal ([delta]%R) as it varies with particle size. For initial biosensing measurements, the surface plasmon resonance microscopy examines each hybridization-adsorption of DNA-decorated gold nanoparticle on gold surface functionalized with either completely or partially complementary DNA monolayer.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The development and characterization of biomolecule sensor formats based on the optical technique Surface Plasmon Resonance (SPR) Spectroscopy and electrochemical methods were investigated. The study can be divided into two parts of different scope. In the first part new novel detection schemes for labeled targets were developed on the basis of the investigations in Surface-plamon Field Enhanced Spectroscopy (SPFS). The first one is SPR fluorescence imaging formats, Surface-plamon Field Enhanced Fluorescence Microscopy (SPFM). Patterned self assembled monolayers (SAMs) were prepared and used to direct the spatial distribution of biomolecules immobilized on surfaces. Here the patterned monolayers would serve as molecular templates to secure different biomolecules to known locations on a surface. The binding processed of labeled target biomolecules from solution to sensor surface were visually and kinetically recorded by the fluorescence microscope, in which fluorescence was excited by the evanescent field of propagating plasmon surface polaritons. The second format which also originates from SPFS technique, Surface-plamon Field Enhanced Fluorescence Spectrometry (SPFSm), concerns the coupling of a fluorometry to normal SPR setup. A spectrograph mounted in place of photomultiplier or microscope can provide the information of fluorescence spectrum as well as fluorescence intensity. This study also firstly demonstrated the analytical combination of surface plasmon enhanced fluorescence detection with analyte tagged by semiconducting nano- crystals (QDs). Electrochemically addressable fabrication of DNA biosensor arrays in aqueous environment was also developed. An electrochemical method was introduced for the directed in-situ assembly of various specific oligonucleotide catcher probes onto different sensing elements of a multi-electrode array in the aqueous environment of a flow cell. Surface plasmon microscopy (SPM) is utilized for the on-line recording of the various.

Download or read book Surface Plasmon Enhanced Fluorescence for Biological Imaging written by Shengnan Huang (Ph.D.) and published by . This book was released on 2020 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluorescence imaging offers high spatio-temporal resolution, low radiation dosage exposure, and low cost among all the available imaging modalities, for example, magnetic resonance imaging, computerized tomography and positron emission tomography. Imaging probes of high emissivity and photostability are the key to achieving fluorescence imaging with high signal-to-background ratio (SBR). One promising approach to developing highly bright and stable imaging probes is through surface plasmon enhanced fluorescence. In the first part of the thesis, we develop a fluorescent probe with high site-specificity and emission efficiency by exploiting the targeting-specificity of M13 virus and co-assembling plasmonic nanoparticles and visible dye molecules on the viral capsid. Practical factors controlling fluorescence enhancement, such as nanoparticle size and dye-to-nanoparticle distance, are studied in this project. Lastly, the highly fluorescent probe is applied for in vitro staining of E. coli. The methodology in this work is amendable to developing a wide range of affinity-targeted fluorescent probes using biotemplates. Compared to visible and near infrared spectrum, short-wave infrared (SWIR, 900-1700 nm) spectrum promises high spatial resolution and deep tissue penetration for fluorescence imaging of biological system, owning to low tissue autofluorescence and suppressed tissue scattering at progressively longer wavelengths. In the second part of the thesis, a bright SWIR imaging probe consisting of small SWIR dyes and gold nanorods is developed for in vivo imaging. Fluorescence enhancement is optimized by tuning the dye density on the gold nanorod surface. The SWIR imaging probes are applied for in vivo imaging of ovarian cancer. The effect of targeting modality on intratumor distribution of the imaging probes is studied in two different orthotopic ovarian cancer models. Lastly, we demonstrate that the plasmon enhanced SWIR imaging probe has great potential for fluorescence imaging-guided surgery by showing its capability to detect submillimeter-sized tumors. Apart from enhancing the SWIR down-conversion emission above, surface plasmon enhanced SWIR up-conversion emission is another promising approach to achieving "autofluorescence-free" imaging with minimal tissue scattering. In the third part of the thesis, we use gold nanorods to enhance the up-conversion emission of small SWIR dyes. The mechanism of surface plasmon enhanced up-conversion emission is studied. The up-conversion fluorescence shows much higher SBR than down-conversion fluorescence in non-scatting biological solution and scatting medium. Lastly, we demonstrate in vivo imaging for the first-time using SWIR up-conversion fluorescence with exceptional image contrast.

Download or read book Principles of Surface Enhanced Raman Spectroscopy written by Eric Le Ru and published by Elsevier. This book was released on 2008-11-17 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: SERS was discovered in the 1970s and has since grown enormously in breadth, depth, and understanding. One of the major characteristics of SERS is its interdisciplinary nature: it lies at the boundary between physics, chemistry, colloid science, plasmonics, nanotechnology, and biology. By their very nature, it is impossible to find a textbook that will summarize the principles needed for SERS of these rather dissimilar and disconnected topics. Although a basic understanding of these topics is necessary for research projects in SERS with all its many aspects and applications, they are seldom touched upon as a coherent unit during most undergraduate studies in physics or chemistry. This book intends to fill this existing gap in the literature. It provides an overview of the underlying principles of SERS, from the fundamental understanding of the effect to its potential applications. It is aimed primarily at newcomers to the field, graduate students, researchers or scientists, attracted by the many applications of SERS and plasmonics or its basic science. The emphasis is on concepts and background material for SERS, such as Raman spectroscopy, the physics of plasmons, or colloid science, all of them introduced within the context of SERS, and from where the more specialized literature can be followed. - Represents one of very few books fully dedicated to the topic of surface-enhanced Raman spectroscopy (SERS) - Gives a comprehensive summary of the underlying physical concepts around SERS - Provides a detailed analysis of plasmons and plasmonics
