In article number 1702990, Peer Fischer, Frank Neubrech, Na Liu, and co‐workers fabricate three‐dimensional palladium helices by nanoglancing angle deposition exhibiting strong circular dichroism for sensitive hydrogen detection in the flammable range. The linearity of the sensor response is significantly improved using palladiumgold hybrid helices. Such a chiral plasmonic sensor scheme is of potential...
In this article, a chiral plasmonic hydrogen‐sensing platform using palladium‐based nanohelices is demonstrated. Such 3D chiral nanostructures fabricated by nanoglancing angle deposition exhibit strong circular dichroism both experimentally and theoretically. The chiroptical properties of the palladium nanohelices are altered upon hydrogen uptake and sensitively depend on the hydrogen concentration...
A light‐activated genome editing platform based on the release of enzymes from a plasmonic nanoparticle carrier when exposed to biocompatible near‐infrared light pulses is described. The platform relies on the robust affinity of polyhistidine tags to nitrilotriacetic acid in the presence of copper which is attached to double‐stranded nucleic acids self‐assembled on the gold nanoparticle surface. A...
Laser heating of individual cells in culture recently led to seminal studies in cell poration, fusion, migration, or nanosurgery, although measuring the local temperature increase in such experiments remains a challenge. Here, the laser‐induced dynamical control of the heat‐shock response is demonstrated at the single cell level, enabled by the use of light‐absorbing gold nanoparticles as nanosources...
Photoconductive antennas are commonly used for terahertz wave generation and detection. However, their relatively low radiation power and detection sensitivity often place limitations on the signal‐to‐noise ratio and operation bandwidth of terahertz imaging and spectroscopy systems. Several different techniques are attempted to address these limitations. The most promising ones take advantage of the...
