Visible light can be used to create electrodes from conductive plastics completely without hazardous chemicals. This is shown in a new study carried out by researchers at Linköping and Lund universities, Sweden. The electrodes can be created on different types of surfaces, which opens up for a new type of electronics and medical sensors.

Using proteins from a common tobacco plant virus, McGill chemistry researchers have developed a simple, eco-friendly way to arrange gold nanoparticles into ultrathin sheets, strengthening the particles’ optical properties. The result: cheaper, safer materials for solar panels, sensors and advanced optical devices. Gold nanoparticles are only effective in strengthening optical signals when the nanoparticles are arranged on a surface and spaced at exact distances. Until now, cr

One of the enigmas of life is emergence, when the whole becomes more than its parts. Flocks of birds can instantly change direction when a predator appears, guided not by a lead bird but by a collective intelligence that no single bird can possess on its own. Multitudes of molecules skitter chaotically in a cell, but certain ones find each other, interact, and give rise to sophisticated cellular structures and functions that could not have been predicted by studying the molec

Bacteria that multiply on surfaces are a major headache in healthcare when they gain a foothold on, for example, implants or in catheters. Researchers at Chalmers University of Technology in Sweden have found a new weapon to fight these hotbeds of bacterial growth – one that does not rely on antibiotics or toxic metals. The key lies in a completely new application of this year's Nobel Prize-winning material: metal-organic frameworks. These materials can physically impale, pun

Drugs are often only needed at a specific site in the body. That is why medical research has long been trying to deliver them precisely to where they are needed – in the case of a stroke, directly to the vicinity of the blood clot. A team from ETH Zurich has now achieved decisive breakthroughs on several levels in pursuit of this goal. The results have been published in the prestigious journal Science. The authors of the publication include Professor Tessa Lühmann from the In

The study found that rectification happens because of the way the electric charges lining the inside of the pore influence ion movement. The charge distribution makes it easier for ions to pass in one direction than the other, like a one-way valve. Gating, on the other hand, occurs when a large flow of ions leads to a charge imbalance that structurally destabilizes the pore, which causes part of the pore to temporarily collapse, blocking the flow of ions.
