Our new paper in Journal of magnetism and magnetic materials

Congratulations to our new paper ” Unexpected large transverse magneto-optic Kerr effect at quasi-normal incidence in commercial disk-based magnetoplasmonic crystals” by Cichelero, M. A. Oskuei, M. V. Kataja, S.M. Hamidi, G. Herranz. We investigate the transverse magneto-optic Kerr effect (TMOKE) of magnetoplasmonic crystals grown on top of commercial disks. From full angle-resolved scans we canRead More…

Manipulation of the dephasing time by strong coupling between localized and propagating surface plasmon modes

Strong coupling between two resonance modes leads to the formation of new hybrid modes exhibiting disparate characteristics owing to the reversible exchange of information between different uncoupled modes. Here, we realize the strong coupling between the localized surface plasmon resonance and surface plasmon polariton Bloch wave using multilayer nanostructures. An anticrossing behavior with a splitting energy of 144 meVRead More…

Nano “Solar Panels” Turn Yeast Cells into Biofactories

By decorating the outside of baker’s yeast cells with light-harvesting semiconductor nanoparticles, a research team from Harvard University and the University of Pennsylvania, USA, has turned the cells into tiny factories to churn out substances relevant to pharmaceutical and fine-chemical manufacture. The semiconductor fragments act as tiny “solar panels” that shunt photogenerated electrons into the yeastRead More…

Green Photonics

Lasers are not all that’s green in the photonics industry. Photonics technologies are helping to reduce energy consumption, they’re used in the manufacturing of renewable energy technologies, and many green, sustainable practices are adhered to throughout the photonics industry. And, yes, trend that it is – there is certainly green in going green.  New technologies andRead More…

“Stealth” Coating for Bio-Friendly Nanoprobes

A team of researchers in Germany and Australia report using photopolymerization to coat upconverting nanoparticles (UCNPs) with a “stealth cap” that increases nanoparticle stability and biocompatibility. The work, the researchers believe, could increase the usefulness of UCNPs in medical applications. Results from in vitro demonstrations showed that the UCNPs with the hydrophilic cap maintain photoluminescence when submerged inRead More…

Light-bending tech shrinks kilometers-long radiation system to millimeter s

The DESY accelerator facility in Hamburg, Germany, goes on for miles to host a particle making kilometer-long laps at almost the speed of light. Now researchers have shrunk such a facility to the size of a computer chip. A University of Michigan team in collaboration with Purdue University created a new device that still accommodatesRead More…

Real-Time Tracing of Hard-to-Diagnose Bacteria

Lung infections due to Gram-negative bacteria are notoriously difficult to diagnose rapidly for prompt treatment. A new procedure involving an optical probe and a fluorescent marker could make those pulmonary predators pop out on a display screen, leading to rapid diagnosis of potentially deadly pneumonia. Engineering a fluorescent marker So-called Gram-negative bacteria—the name comes fromRead More…
