Spurred by outstanding optical properties, chemical stability, and facile bioconjugation, plasmonic metals have become the first-choice materials for optical signal transducers in biosensing. While the design rules for surface-based plasmonic sensors are well-established and commercialized, there is limited knowledge of the design of sensors based on nanoparticle aggregation. The working principle of biosensors built around […]

amorphous Scientists have dedicated their efforts to studying topological materials, focusing on the shape, or topology, of their electronic structures. These materials exhibit unique properties that have the potential to be harnessed for next-generation devices, despite their invisible nature in real space. Initially, it was believed that only crystalline materials, characterized by highly ordered atoms […]

Some materials have special universal properties protected against perturbations. Such properties are theoretically described by topology, a branch of mathematics concerned with the properties of geometrical objects that are unchanged by continuous deformations. So-called topological insulators are electronic materials that have a bulk band gap like an ordinary insulator but have conducting states on their […]

The development of superconducting devices was greatly stimulated after the acceptance of the basic theory of superconductivity proposed in 1957 by John Bardeen, Leon Cooper, and Robert Schrieffer – BCS theory. The basic idea is that the electron waves in the superconducting state no longer act independently, as in Bloch’s model. Instead, they are paired […]

Organic compounds of sulphur that contain the group -S- linked to two hydrocarbons are known as thioethers. This alternative name to sulphides comes from the fact that they are analogues of ethers in which the oxygen is replaced by a sulphur; thioethers are generally more reactive than ethers, though. The formation of thioether structures increases […]

Two-dimensional (2D) materials are an ideal platform to artificially engineer heterostructures with new functionalities due to the weak van der Waals bonding between layers. Monolayers hosting symmetry-broken phases, such as superconductivity, magnetism, ferroelectricity, charge density waves (CDWs), or multiferroicity, represent the most interesting building blocks to design novel phases of matter. One of the main […]

Polaritons attract wide attention due to their ability to confine and guide light at the nanometre scale. These capacities are key for the development of ultrasmall resonators and waveguides that can be used for sensing, heat transfer and optical circuitry applications. But, what are polaritons in the first place? If, for the sake of the […]
