The integration of consumer electronics with advanced imaging and analytical platforms holds great promises for medical point-of-care diagnostics and environmental rapid field testing for pollutants and viruses. A recent example is a Google Glass application and a server platform for instant, wireless diagnostic testing of a variety of health conditions and diseases. This technology allows Google Glass wearers to use the hands-free camera on the device to send images of diagnostic tests that screen for conditions such as HIV or prostate cancer.

In the area of development cooperation which, like disaster relief, is often confronted with demands and scenarios that are hard to predict, nanotechnology based solutions can offer interesting perspectives for medical care, water treatment, agriculture and food, as well as rural infrastructure development in developing countries. A publication aims to inform managers and staff working in emergency response services and development cooperation as well as related institutions about the innovation potential of nanotechnology for their respective fields of work, and to highlight areas of overlap. The 84-page brochure also addresses companies and industry representatives that are already operating in this area or are interested in tapping in to this market.

Friction is present in numerous physical phenomena occurring at all length scale. About 1/3 of the world's primary energy is dissipated in mechanical friction and 80% of machinery components' failure is caused by wear. Friction and wear will also become bottlenecks for micro-/nano-mechanical systems (MEMS and NEMS) featured with sliding components. Superlubricity, a phenomenon where the friction almost vanishes between two solid surfaces, will be the key to solve these problems and researchers now report a breakthrough in macroscale superlubricity.

While nanotechnology combines the knowledge of physics, chemistry and engineering, AI has heavily relied on biological inspiration to develop some of its most effective paradigms such as neural networks or evolutionary algorithms. Bridging the link between current nanosciences and AI can boost research in these disciplines and provide a new generation of information and communication technologies that will have a large impact in our society, probably providing the means so that technology and biology merge

Covetics - this new class of materials marks a game-changer for engineers and designers that have long sought to combine high-strength carbon with metal in their pursuit to improve metal's performance. For the first time the hybrid fuses nanocarbons and metal in a bond that is stronger than graphene-like sp2 carbon bonds. To create covetics, its inventors developed a new method of carbon catalyzation which uses molten metal and metal alloys as an ionizing medium. Nanocarbon structures form in situ while bonding to the metal ionizing medium.

It is a challenge to measure the temperature variation at the surface of nanoparticles under optical illumination since nano-localized temperature variation is the most important parameter for applications ranging from nanomedicine to photonics. In particular, the conversion of light to heat trough the exploitation of the Localized Plasmonic Resonance (LPR) has enabled a remarkable breakthrough in fighting cancer. Now, researchers have advanced the monitoring of nanoscale temperature variations under optical illumination by combining the properties of gold nanorods and the capabilities of thermotropic cholesteric liquid crystals.

As the use of antibiotics increases for medical, veterinary and agricultural purposes, the increasing emergence of antibiotic-resistant strains of pathogenic bacteria is an unwelcome consequence. The incidence of the multidrug resistance (MDR) of bacteria which cause infections in hospitals/intensive care units is increasing, and finding microorganisms insensitive to more than 10 different antibiotics is not unusual. The emergence of superbugs has made it imperative to search for novel methods, which can combat the microbial resistance. Thus, application of nanotechnology in pharmaceuticals and microbiology is gaining importance to prevent the catastrophic consequences of antibiotic resistance.
