A Bragg grating (BG) is a one-dimensional optical device that may reflect a specific
wavelength of light while transmitting all others. It is created by the periodic fluctuation of the …

Techniques based on plasmonic resonance can provide label-free, signal enhanced, and
real-time sensing means for bioparticles and bioprocesses at the molecular level. With the …

This paper reports the fabrication of highly stable semi-hollow gold-silver nanostars
(hAuAgNSts). Galvanic replacement between silver nanostars (AgNSts) and chloroauric …

Refractory nanostructures can be low-cost and chemically and thermally robust alternatives
to metal-based plasmonic materials. While transition metal nitrides have received much …

We report adjusting the charge-transfer-plasmon (CTP) resonances of aluminum (Al)
bowties on suspended monolayer graphene via controlled nanofabrication and focused …

Nanotechnology has been used in many biosensing and medical applications, in the form of
noble metal (gold and silver) nanoparticles and nanostructured substrates. However, the …

Akahoya is a volcanic soil rich in alumina, primarily deposited in Kyushu, Japan. We have
found that Akahoya adsorbs bacteria in the water surrounding cattle grazing areas …

The plasma membrane of cancer cells displays differences in lipid and protein composition
which distinguish them from healthy cells. Certain molecules have such prominent …

Al nanostructures have unique optical properties such as widely tunable surface plasmon
resonances from deep UV to NIR that can be used for label-free fluorescence enhancement …

Recently, the ineffectiveness of conventional antibiotic treatments against multidrug-resistant
bacteria stimulated the development of novel effective disinfection technologies. Ultraviolet …
