Nanotechnology-enabled low-cost, point-of-care, self-test of sodium in the comfort of your home

nanoparticlesResearchers have developed a point-of-care, portable, rapid, and cost-effective test for clinical diagnosis of sodium, which uses a paper printed colorimetric sensor that is based on Curcumin-functionalized copper (CuC) nanoparticles. They demonstrate that the proposed CuC paper strip can be used for detecting Na+ concentration within the whole physiological range in both blood serum and urine. Sodium is a vitally important electrolyte present in all body fluids and it plays a crucial role in maintaining normal body function, including nerve and muscle function.

Nanotechnology in the Olympic Winter Games

skiingModern sports equipment often appears to be a showcase for new material technologies and nowhere has this been more true than in global sport competitions. Some of the high-tech materials used by athletes in competitive winter sports are using nanomaterials. But, as the 2022 Beijing Winter Olympics has shown, other areas have benefited from nanotechnologies and nanoscience as well: ice skating, wearable monitoring devices, and even nanomaterial-based Braille printing of Olympic service manuals and spectator guides for vision impaired readers.

Interface engineering enables tunable topological transitions in biaxial crystals

field-distributionsPolaritons 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

The future of contact lenses - lab-on-a-lens, augmented reality, and head-up displays

smart-contact-lensOngoing 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.

How advanced nanotechnology drives ultrathin membrane development for separations

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.

Combination of engineered resonators and nanotechnology for sensing hazardous environments

resonatorResonance-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.
