When we think of faster, cheaper electronics, we usually think “smaller transistors.” But the future is also about stacking—adding new layers of components on top of finished silicon chips. That’s called back‑end‑of‑line (BEOL) integration, and it only works if everything you add can be made at low temperatures (generally below ~400–450 °C), otherwise you damage […]

Light can do remarkable things, but it has limitations. Ordinary photons are bound by diffraction, which sets a limit on how tightly they can be confined in space. This is why focusing light to spots smaller than about half its wavelength is so difficult. But in certain materials, photons couple to vibrations of atoms or […]

When you hear the word nanoparticle, it might sound like something futuristic or abstract. In reality, nanoparticles—tiny structures tens of thousands of times smaller than the width of a human hair—are already part of modern medicine. Some are used to deliver drugs more effectively, while others help doctors see inside the body by acting as […]

Nanoparticles, those minuscule marvels measured in billionths of a metre, hold immense promise for revolutionizing cancer treatment. Their ability to deliver drugs directly to tumours could transform therapies, but only if they can navigate the dense, complex environment of tumour tissue. A new review , that includes a new experimental data set, explores this challenge […]

Nanotechnology is like a playground for scientists, where they tinker with materials at the scale of atoms to create new tools and devices with extraordinary properties. One of the most exciting areas in this field involves nanographenes, which are tiny pieces of graphene—a single layer of carbon atoms arranged in a honeycomb pattern, known for […]

The future of medicine may very well lie in the personalization of health care—knowing exactly what an individual needs and then delivering just the right mix of nutrients, metabolites, and medications, if necessary, to stabilize and improve their condition. To make this possible, physicians first need a way to continuously measure and monitor certain biomarkers […]

Molecular spintronics is an emerging field that combines ferromagnetic materials with organic or metal–organic semiconductors. It benefits from the unique and exceptional properties of organic molecules, which go beyond inorganic ones. The strong response of many organic molecules to electrical, optical, ferromagnetic or antiferromagnetic stimuli bring new potential functionalities to the spintronic device. An effective […]

Imagine a close basketball game that comes down to the final shot. The probability of the ball going through the hoop might be fairly low, but it would dramatically increase if the player were afforded the opportunity to shoot it over and over. A similar idea is at play in the scientific field of membrane […]

A new imaging technique can give scientists a much closer look at fibril assemblies, stacks of peptides like amyloid beta, most notably associated with Alzheimer’s disease. These cross-β fibril assemblies are also useful building blocks within designer biomaterials for medical applications, but their resemblance to their amyloid beta cousins, whose tangles are a symptom of […]

Superconductors can carry large electrical currents without any resistance. One situation where they don’t carry currents without resistance is when there is too much current. By designing microscopic electronic components made from very thin superconductors, researchers can use this effect to create a switch, like a transistor. Nanowire superconducting switching devices (called nanocryotrons, or nTrons […]
