Polaritons in biaxial crystals offer a promising route to manipulate nanoscale light-matter interactions. The dynamic modulation of their dispersion is of great significance for future integrated nano-optics but remains challenging. Researchers theoretically demonstrate and experimentally verify such tailored polaritons at the interface of heterostructures. The interface engineering may shed new light on programmable polaritonics, energy transfer, and neuromorphic photonics

Ongoing smart contact lens research ranges from biosignal detection (intraocular pressure, glucose, cortisol) to therapeutic tools (aniridia, chronic ocular inflammation) and advanced features such as aumented reality displays and personalized designs using 3D-printing technology. Some of these technologies are already finding their way from the lab into commercial applications. The development of next-generation, smart contact lens technology is not just simply one field of bioelectronics but rather a complex, interdisciplinary effort that includes development of biocompatible materials; development of intuitive interfaces; and development of integration technologies capable of smart contact lens research.

Driven by advanced nanomaterials and nanofabrication technologies, tremendous progress has been made over the last 15 years in making ultrathin membranes based on a variety of advanced nanomaterials and nanotechnologies. Further pushing membrane thickness to sub-50 nm or even atomic level is appealing to researchers, with the ultrafast permeance that may be enabled and ultimate understanding of formation and transport at the extremely low thickness that can be significantly different from their thicker counterparts.

Resonance-based sensors can be used as an advanced tool for gas sensing as they show several advantages as compared to conventional gas sensors like metal-oxide semiconductor and electro-chemical gas sensors. With the introduction of an additional metamaterial layer over the sensor, the selectivity of these sensors can be improved. These article focuses mainly on metamaterial-based split ring resonators (SRR) and complementary SRRs (CSRRs) structures used in several sensing applications.

A recent review article highlights how nanoscience and nanotechnology can solve three acute problems in the treatment, prevention, and diagnosis of viruses like SARS-CoV-2: 1) synthesis of novel drugs and vaccines based on nanocarriers with enhanced efficiency and reduced side-effects for the treatment of the current pandemic and the prevention of future virus attacks; 2) design of protective equipment based on nanoparticles, such as medical face masks and outfits and 3) development of nanobiosensors for early detection of infections in a maximally efficient way.

Combining the benefits of both fluid and solids, researchers have demonstrated various functions for their slimebots, including navigation in narrow channels much smaller than their size; object capture operations via the curl or endocytosis modes; and circuit repair and controlled switching using their own conductive properties that can even be reconfigured as self-healing strain sensors for monitoring human motion. The widely applicable working environment of these novel magnetic slime robots make them promising for future applications in biomedical and wearable devices.

A lithography-free method for printing optical metasurfaces with resonant laser printing can achieve metasurfaces for structural colors, optical holograms, and diffractive optical elements, with an energy consumption of less than 1 nanojoule and a print time down to 1 nanosecond per dot. The performance of this ink-free laser color printing with a resolution of more than 100 000 dpi by far exceeds the output of conventional laser printers. The nanoscale structures made on a multi-layer film are robust and typically could last longer than most inks or pigments.
