Adding nanoparticles to the surface of tumour cells could make them more susceptible to treatment with particular cancer drugs, according to new research at MIT. The study showed that nanoparticles tethered to the cell surface can increase the effects of forces exerted on the tumour cells by physiological fluids flowing within the body, which makes […]

Macrophages are one of the main ports of entry for the human immunodeficiency virus (HIV-1), but how the virus actually enters macrophages is still poorly understood. A team of researchers in China and the US have now made a new viral tracking tool by encapsulating HIV-1 in fluorescent quantum dots to observe how the virus […]

Immersion lenses (lenses that are immersed in a liquid, such as oil or water) can focus light into a spot size smaller than that possible in free space. Such devices are difficult to make, however, and often need to be hand polished for optimal performance. Now, a team of researchers at Harvard University in the […]

Soft biological tissue is almost completely transparent to short-wave infrared (SWIR) light but nanoscale probes emitting at these wavelengths that can be injected into the body are still lacking. A team of researchers in the US and Germany has now overcome this problem with a new class of SWIR-emitting indium-arsenide-based quantum dots. Thanks to their […]

Ferroelectric domain walls could be used as active elements for next-generation non-volatile memories, logic gates and energy-harvesting devices, but no real working nanodevices exploiting these nanostructures has been made to date. Researchers in Spain have now fabricated a multiferroic tunnel junction based on ferromagnetic La0.7Sr0.3MnO3 electrodes separated by an ultrathin ferroelectric BaTiO3 tunnel barrier that […]

Magnonics (the study of excitations in a magnetic material) may well replace electronics as the basis of modern computing. This would drastically increase energy efficiency and provide devices that can be miniaturized beyond the limit of current technology. However, the control of magnetic textures in nano-sized magnets is not straightforward to achieve. A team of […]

Researchers in France have created an artificial synapse based on ferroelectric tunnel junctions that can autonomously learn to recognize patterns. They have also succeeded in modelling the synapse’s plasticity by looking at how its resistance varies with varying applied voltage. The device, also known as a memristor, might be used to make intelligent artificial neural […]

As the scale of integrated circuits (ICs) continues to shrink, the lack of practical methods for imaging their complex internal structure has hampered feedback for quality control and product development. A collaboration led by Mirko Holler at the Paul Scherrer Institut in Switzerland has published work in Nature that shows how X-rays can be used […]

Cleaning up viscous, or heavy, crude oil after a spill is difficult and new techniques to do this are sorely needed. Researchers at the University of Science and Technology of China in Hefei have now developed a new graphene-wrapped sponge that when heated can rapidly suck up oil from water into its pores…… http://nanotechweb.org/cws/article/tech/68441 Graphene-wrapped […]

Leukosomes are a promising new type of nanoparticle for use in targeted drug and gene delivery. Preloaded with leukocyte proteins, the particles cloak themselves in a shroud of host protein. Researchers from the Houston Methodist Research Institute in Texas have investigated this coating to find out how they evade the host immune system…… http://nanotechweb.org/cws/article/tech/68448 Leukosomes […]

Fabricating materials with strengths that approach theoretically predicted values is no easy task, and most techniques to make stronger materials rely on controlling defects so that dislocations can no longer move as freely. Industrial single-phase nanocrystalline alloys and single-phase metallic glasses, for example, can be very strong, but they usually soften at relatively low strains […]

The self-assembly of macromolecules into organized, hierarchical structures is one of the most characteristic features of biological systems, but mimicking this process in the lab with artificial materials is no easy task. Now, a team of researchers at the University of Massachusetts at Amherst has succeeded in self-assembling such superstructures by simply mixing together proteins […]

A new 2D material just one atom thick has been made by an international team of researchers led by Axel Enders. Dubbed hexangonal boron–carbon–nitrogen (h-BCN), the material could offer many of the benefits of graphene, which is a hexagonal lattice made of just carbon. But unlike graphene, h-BCN has a direct electronic band gap, which […]

Tooth enamel is both hard and resistant to impact, which makes it an extremely durable material that lasts a lifetime. A team of researchers at the University of Michigan in the US have now succeeded in making the first faithful replica of this enamel, which not only matches its structure but also its properties. The […]

Silicon carbide is a promising single-photon source and a good material out of which to make quantum bits (qubits) and nanoscale sensors based on individual “colour centres” (luminescing crystal defects that can emit individual photons)…. http://nanotechweb.org/cws/article/tech/68052

The potential to treat disease by blocking and stimulating nerves directly, rather than through the administration of drugs, is attracting mounting interest. The approach may be effective for a range of non-infectious non-cancerous conditions including asthma, heart conditions, diabetes, obesity and irritable bowel syndrome. nanotechweb.org caught up with some of the speakers at innoLAE 2017 […]
