Natural non-wetting structures, particularly lotus leaves (Fig. 1a), have inspired the development of synthetic liquid-repellent surfaces. These surfaces rely on the formation of a stable air–liquid interface, but present limited repellency to oils with high contact angle hysteresis, failure under […]

The way in which nature manages to create functional diversity in matter is probably the wisest guide for biomaterials engineers, who are always looking for new creative processes to come up with new materials. The conventional way of designing complex […]

Nowadays, there is a growing demand for new biosensors capable of detecting specific molecules, contaminants or toxic substances in food, drinking water, air, blood and so forth, with a high degree of sensitivity and specificity. Furthermore, we preferably want these […]

Human brain has about 85 billion neurons. Each neuron forms thousands of chemical and electrical synapses with other neurons. To record the synaptic activity of each neuron in the brain an intracellular probe with a millivolt scale is required. Glass […]

Have you ever observed how a drop of coffee dries? As water evaporates, its suspended particles are deposited in a ring-like fashion in a phenomenon known as the coffee-ring effect. Obviously, this effect is undesirable in the numerous practical applications […]

Just a few years ago, nanoparticles broke into almost every laboratory in the world in one way or another. It marked a boom in nanoscience and nanotechnology. The demand for these new ultrafine particles, halfway between the bulk scale and […]

Nowadays we are getting more and more accustomed to making use of new technologies shortly after they have been developed. We like the idea of immediacy and our wishes coincide well with the commercial interests of industry. Nevertheless, there is […]

If you have ever faced that thankless task of cleaning fish, for sure you will have realized, at least envisaged, the complex architecture of the fish’s natural armour. Fish scales play the role of a skeleton which provides both protection […]

Thin films are defined as material layers ranging from nanometers to several micrometers of thickness that are deposited onto a matrix in order to modify its physical characteristics. Although solar cells conform a relevant field of application, it may be […]

You have probably heard of the plastic island, an enormous area full of plastic garbage, gathered by oceanic currents, in the North Pacific Ocean. In the last few decades the amount of plastic debris in this area has increased […]
