Optimal colorimetric sensing based on gold nanoparticle aggregation

Materials

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 […]

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 […]

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 […]

Surfaces are at the frontier of every solid. They provide versatile supports for functional nanostructures and mediate essential physicochemical processes. Intimately related to two-dimensional materials, interfaces and atomically thin films often feature distinct electronic states with respect to the bulk, which is key to many relevant properties, such as catalytic activity, interfacial charge-transfer, and crystal […]

One-dimensional metal−organic chains often possess a complex magnetic structure, susceptible to modification by alteration of their chemical composition. The possibility to tune their magnetic properties provides an interesting playground to explore quasi-particle interactions in low-dimensional systems. These systems have potential applications in the fabrication of nanodevices for spin sensing, spintronics, quantum computing based on the […]

Usually, optical activity is understood as the ability some substances have to change the handedness of polarized light when it goes through them. Molecules that show optical activity have no plane of symmetry. So-called chiral matter broadly describes structures for which left- or right-handed mirror images are non-superimposable, or, equivalently, that lack improper rotation axes […]
