Abstract

Plasmonic nano-antennas have proven the outstanding ability of sensing chemical and physical processes down to the nanometer scale. Sensing is usually achieved within the highly confined optical fields generated resonantly by the nano-antennas, i.e., in contact to the nanostructures. In this paper, we demonstrate the sensing capability of nano-antennas to their larger scale environment, well beyond their plasmonic confinement volume, leading to the concept of “remote” (non contact) sensing on the nanometer scale. On the basis of a bowtie-aperture nano-antenna (BNA) integrated at the apex of a SNOM (Scanning Near-field Optical Microscopy) fiber tip, we introduce an ultra-compact, moveable, and background-free optical nanosensor for the remote sensing of a silicon surface (up to distance of 300 nm). Sensitivity of the BNA to its large scale environment is high enough to expect the monitoring and control of the spacing between the nano-antenna and a silicon surface with sub-nanometer accuracy. This work paves the way towards an alternative class of nanopositioning techniques, based on the monitoring of diffraction-free plasmon resonance, that are alternative to nanomechanical and diffraction-limited optical interference-based devices.

Near-field Localization in Plasmonic Superfocusing: a Nanoemitter on a Tip

Journal Article Neacsu, Catalin; Berweger, Samuel; Olmon, Robert; ... - Nano Letters, 10(2):592–596

The effective focusing of light to sub-wavelength dimensions has been a long standing desire in optics, yet proven challenging even resorting to a multitude of new strategies based on near-field effects, surface plasmon polaritons, and metamaterials1-7. The propagation of surface plasmon polaritons (SPP) on a conical tip to obtain nanoconfined light as proposed theoretically has recently emerged as a particularly promising candidate5-10. On the basis of our previous work, having established coupling of SPPs onto gold metal tips and their radiationless transport11, here, using a refined geometry we provide direct evidence of plasmonic nanofocusing into a localized excitation at themore »« less

Ultrasensitive Tip- and Antenna-Enhanced Infrared Nanoscopy of Protein Complexes

Journal Article O'Callahan, Brian; Hentschel, Mario; Raschke, Mark; ... - Journal of Physical Chemistry C

Surface enhanced infrared absorption (SEIRA) us-ing resonant plasmonic nanoantennas enables zeptomolar detection sensitivity of (bio)analytes, although with diffraction limited spa-tial resolution. In contrast, infrared scattering-scanning near-field optical microscopy (IR s-SNOM) allows simultaneous imaging and spectroscopy with nanometer spatial resolution through vibrational coupling to the antenna mode of a probe tip. Herein, we combine these two approaches to image distributions of ferritin protein com-plexes adsorbed onto IR-resonant Au nanoantennas. The joint tip- and antenna-enhancement yields single protein complex sensitivity due to coupling with the vibrational modes of the bioanalytes. The coupling is revealed through IR s-SNOM spectra in the form ofmore »« less

Campanile Near-Field Probes Fabricated by Nanoimprint Lithography on the Facet of an Optical Fiber

Journal Article Calafiore, Giuseppe; Koshelev, Alexander; Darlington, Thomas; ... - Scientific Reports

One of the major challenges to the widespread adoption of plasmonic and nano-optical devices in real-life applications is the difficulty to mass-fabricate nano-optical antennas in parallel and reproducible fashion, and the capability to precisely place nanoantennas into devices with nanometer-scale precision. In this study, we present a solution to this challenge using the state-of-the-art ultraviolet nanoimprint lithography (UV-NIL) to fabricate functional optical transformers onto the core of an optical fiber in a single step, mimicking the 'campanile' near-field probes. Imprinted probes were fabricated using a custom-built imprinter tool with co-axial alignment capability with sub < 100 nm position accuracy, followedmore »« less

Plasmon 3D Electron Tomography and Local Electric-Field Enhancement of Engineered Plasmonic Nanoantennas

Journal Article Archanjo, B.; Vasconcelos, T.; Oliveira, B.; ... - ACS Photonics

Plasmonic nano-antennas are pushing the limits of optical imaging resolution capabilities in near-field scanning optical microscopy (NSOM). Accordingly, these techniques are driving the basic understanding of photonic and optoelectronic nanoscale devices with applications in sensing, energy conversion, solid-state lighting and information technology. Imaging the localized surface plasmon resonance (LSPR) at the nanoscale is a key to understanding the optical responses of a given tip geometry in order to engineer better plasmonic nano-antennas for near-field experiments. In recent years the advancement of focused ion beam technology provides the ability to directly modify plasmonic structures with nanometer resolution. Also, scanning transmission electronmore »« less

A nanochannel through a plasmonic antenna gap: an integrated device for single particle counting

Journal Article Fernandez-Cuesta, Irene; West, Melanie; Montinaro, Enrica; ... - Lab on a chip (Print)

Plasmonic nanoantennas are ideal for single molecule detection since they nano-focus the light beyond diffraction and enhance the optical fields by several orders of magnitude. But delivering the molecules into these nanometric hot-spots is a real challenge. Here, we present a dynamic sensor, with label-free real-time detection capabilities, which can detect and count molecules and particles one by one in their native environment independently of their concentration. To this end, we have integrated a 35 nm gap plasmonic bowtie antenna with a 30 nm × 30 nm nanochannel. The channel runs through the antenna gap, and delivers the analyte directlymore »« less
