A Stable Biotin-Streptavidin Surface Enables Multiplex, Label-Free Protein Detection by Aptamer and Aptamer-Protein Arrays Using Arrayed Imaging Reflectometry

open access: yesSensors, 2020
While label-free multiplex sensor technology enables “mixing and matching” of different capture molecules in principle, in practice this has been rarely (if ever) demonstrated. To fill this gap, we developed protocols for the preparation of mixed aptamer-

Magnetic reflectometry of heterostructures

open access: yesJournal of Physics: Condensed Matter, 2014
Measuring the magnetic configuration at complex buried layers and interfaces is an important task, which requires especially a non-destructive probing technique. X-ray resonant magnetic reflectometry (XRMR) combines the non-destructive depth profiling potential of x-ray reflectometry with the excellent sensitivity for magnetic phenomena, utilizing the ...

The Origins of Neutron Reflectometry

open access: yesNeutron News, 2010
The optical properties of slow neutrons, which includes refraction, reflection and interference, were recognized in the very early days of neutron physics. Fermi and co-workers [1] reported the total (or critical) reflection of slow neutrons. Goldberger and Seitz showed that the intensity of reflected and transmitted neutrons follow the same laws as ...

Advancing Reflectometry [PDF]

open access: yesEos, Transactions American Geophysical Union, 2013
Reflectometry, a microwave remote‐sensing technique to extract geophysical data from scattered satellite transmissions, was first demonstrated using Global Navigation Satellite System (GNSS) reflections. Recently, reflectometry has been extended to the reutilization of digital communication satellite signals for Earth remote sensing, now referred to as
