Layer-by-layer assembly of organic films and their application to multichannel surface plasmon resonance sensing [PDF]

open access: yes, 2004
This thesis provides a study of a single chip, multi-channel surface plasmon resonance (SPR) imaging system. The equipment has no moving parts and uses a single sensor "chip" onto which multiple channels can be incorporated.

Critique of optical negative refraction superlensing [PDF]

open access: yes, 2011
Has the ten-year old quest for the optical superlens, based on Veselago’s hypothesis of negative refraction, been a chimera? We argue that Pendry’s alternative prescription of the silver superlens is nothing more than an application of the natural ...

Surface and Bulk Plasmon Excitation on Aluminum Surface at Small to High Grazing Angles

open access: yesAtoms, 2022
We present a series of spectra measured by reflected electron energy loss spectroscopy on an aluminum sample using a cylindrical mirror analyzer. The measurements were performed in the energy range between 250 eV and 2000 eV and with various incident ...

Adaptable Covalent Organic Framework‐Hydrogel Microneedles for Glucose‐Responsive Isoliquiritigenin Delivery in Diabetic Wound Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
We develop a covalent organic framework‐loaded Traditional Chinese Medicine monomer nanodrug delivery system (ISL@bCOF) via boron‐oxygen bonds, a smart response to glucose for delivering AI‐driven isoliquiritigenin (ISL) targeting ZBP1. This dynamic release mechanism, combined with transdermal delivery technology via potent microneedles, can modulate ...

Towards a remote portable bio-affinity surface plasmon resonance analyser for environmental steroidal-pollutants [PDF]

open access: yes, 2003
The widespread presence of chemicals with the capacity to disrupt the endocrine system in both wildlife and humans in our natural environment has increasingly become of major concern in the last ten years.

Gold nano-ripple structure with potential for bio molecular sensing applications

open access: yesSensing and Bio-Sensing Research, 2016
We introduce a simple and cost-effective scheme for bio-sensing using nano-ripple structures. One dimensional metallic nano-ripple structures formed by gas cluster ion beam irradiation have shown polarization of light as well as localized surface plasmon

Exciton-surface plasmon polariton interactions

open access: yesAdvances in Physics: X, 2020
Exciton-surface plasmon polariton (exciton-SPP) interactions in semiconductor-metal hybrid nanostructures connect two fundamentally different quantum mechanical excitations with strikingly different dispersion relations and optical response.

Mimicking Surface Plasmons with Structured Surfaces

open access: yesScience, 2004
Metals such as silver support surface plasmons: electromagnetic surface excitations localized near the surface that originate from the free electrons of the metal. Surface modes are also observed on highly conducting surfaces perforated by holes. We establish a close connection between the two, showing that electromagnetic waves in both materials are ...

Surface plasmons on a quasiperiodic grating [PDF]

open access: yesThe European Physical Journal B - Condensed Matter and Complex Systems, 2003
A method is presented for calculating the frequencies of non-retarded surface plasmons propagating on a semi-inifinite medium with a surface profile described by a one-dimension quasiperiodic function. The profiles are generated, in analogy with previous work on quasiperiodic superlattices, by repeating unitary cells constructed according to an ...

Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells

open access: yesAdvanced Materials, EarlyView.
This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...
