Wireless Nano Irradiance Meter Based on Upconversion Luminescence Lifetime

Advanced Optical Materials, EarlyView.
A wireless nano irradiance meter is developed based on upconversion nanoparticles that enabled local readouts through their luminescence lifetime. This method allows for remote and precise light irradiance quantification in complex media, offering significant potential for light‐based technologies such as photodynamic therapy and nanothermometry ...

Bubble Printing of Anisotropic Clay Nanotubes

Advanced Optical Materials, EarlyView.
Bubble printing patterns of lyotropic liquid crystal nanotubes form toroidal or linear patterns depending on laser movement and colloidal stability. Long nanotubes create radial filament bundles, while poor electrostatic repulsion hinders deposition.

Co‐Solvent‐Aided Opto‐Thermophoretic Printing of Gold Nanorod Assemblies

Advanced Optical Materials, EarlyView.
A focused laser beam creates a thermal gradient, driving the gold nanorods and polymer coils toward the heated region of the glass substrate, i.e, the laser spot. After the adsorption of the polymer on the gold surface, the nanorods start to assemble onto the surface in a ring‐shaped pattern that grows radially until the beam is turned off.

Self‐Assembled Physical Unclonable Function Labels Based on Plasmonic Coupling

Advanced Optical Materials, EarlyView.
This article introduces advanced anti‐counterfeit labels crafted through DNA‐guided self‐assembly of plasmonic nanoparticles. Utilizing nanosphere lithography for dense and precise nanoparticle placement, these labels feature unique, unclonable optical signatures achieved through plasmonic coupling, detectable by an economical 3D‐printed dark field ...

Microlasers Made Entirely from Edible Substances

Advanced Optical Materials, EarlyView.
Several types of microlasers made completely out of edible substances are developed. They can be embedded directly into edible products and enable the sensing of various parameters, including sugar concentration, pH, the presence of bacteria, and exposure to too‐high temperatures.
