Peptoid microsphere coatings to improve performance in sandwich ELISA microarrays

open access: yesSensing and Bio-Sensing Research, 2021
Enzyme-linked immunosorbent assay (ELISA) microarray performance is limited by low assay sensitivity and dynamic range. Increasing the surface area for reagent binding can help to improve performance, but standard techniques such as roughening the ...

Sol-gel fabrication of porous ceria microspheres for thermochemical carbon dioxide (CO2) splitting

open access: yesNuclear Analysis, 2023
Porous CeO2 has been of great interest recently, due to its great catalytic efficiency in splitting CO2 into CO and O2. Porous CeO2 microspheres are the key to scaling up such reactions in the fluidized-bed solar thermochemical reactors.

Composite production by pressure infiltration [PDF]

open access: yes, 2008
This paper presents the possibility of composite block production by using pressure infiltration technology. This method uses the pressure of an inert gas (usually argon or nitrogen) to force the melted matrix material to infiltrate the reinforcing ...

5-Gbit/s BER performance on an all fiber-optic add/drop device based on a taper-resonator-taper structure [PDF]

open access: yes, 2000
We present an all fiber-optic add/drop device based on a taper-resonator-taper structure with improved characteristics. Several gigahertz bandwidths are observed using microspheres having diameters ranging from 30 to 50 μm.

Phase shift spectra of a fiber-microsphere system at the single photon level [PDF]

open access: yes, 2011
We succeeded in measuring phase shift spectra of a microsphere cavity coupled with a tapered fiber using a weak coherent probe light at the single photon level. We utilized a tapered fiber with almost no depolarization and constructed a very stable phase
