Single Airborne Dust Particles using Plasmonic Metal Films with Hole Arrays.
نویسندگان
چکیده
An airborne dust particle is trapped in the hole of a plasmonic metal film with a patterned array of holes (mesh) by pumping air through the mesh. Both scatter-free infrared spectra and scanning electron images are obtained on the same individual airborne dust particle, showing the feasibility of multiple, nondestructive experiments on a single, subwavelength particle. Ultimately, this may help to elucidate the effect of shape, orientation, and crystallinity on IR dust particle spectra.

Plasmonic spectra of individual subwavelength particles under the infrared microscope: Cells and airborne dust
A plasmonic metal film with a subwavelength hole array (a mesh) is used to capture an individual subwavelength particle, like a single yeast cell or airborne dust particle, and an imaging infrared (IR) microscope, records a scatterfree, IR absorption spectrum of the particle. Individual spectra of wavelength scale particles usually suffer from large scattering effects. This paper starts by demo...
متن کاملScatter-Free IR Absorption Spectra of Individual, 3 5 μm, Airborne Dust Particles Using Plasmonic Metal Microarrays: A Library of 63 Spectra
“Indoors or outdoors, dust is unavoidable. And a marvellous fraction of that dust holds the secret to our past”. Dust is collected from outer space to learn about earlier times in our solar system. 4 Minerals from soil, volcanic eruptions, pollution, biological material, and meteorites all contribute to dust in our atmosphere. Skin cells, pollen, fabric fibers, hair, road dust, local soil, agri...
متن کاملInfrared Sensitivity of Plasmonic Metal Films with Hole Arrays to Microspheres In and Out of the Holes
Both experiments and finite difference time domain (FDTD) calculations show that infrared (IR) absorption spectroscopy and IR transmission resonances of metal films with arrays of subwavelength holes (meshes) are more sensitive to material in the holes of the mesh than to material on the front or back surfaces of the mesh. IR extinction spectra of isolated, individual latex (polystyrene) sphere...

متن کاملDeveloping Plasmonics Under the Infrared Microscope: From Ni Nanoparticle Arrays to Infrared Micromesh.
Microscopes typically collect light over large ranges of angles dispersing plasmonic resonances. While this is an advantage for recording spectra of microscopic particles, it is a disadvantage for sensing by resonance shifts. Adaptations are described herein which enable one to identify, manipulate, and examine narrow plasmonic resonances under a microscope. Noting more general familiarity with...
