Hygienic surfaces, biocidal and self-cleaning coatings


Microbian evolution on a wide variety of surfaces can produce phenomena such as corrosion, dirt, smells and even serious hygiene and health problems.

It is well known there is a great interest in the design and development of the so-called “hygienic surfaces”, referring to surfaces that not only provides biocidal activity but also to those that are easy to clean and even self-cleaning.

Achieving these properties on a surface is possible by means of coatings and treatments on specific surfaces, and in which nanotechnology plays a key role. Most of these coatings acquire their biocidal/self-cleaning capacity by incorporating specific nanoparticles: basically silver (Ag) and titanium oxide (TiO2).

The development of these coatings is key mainly in sectors such as architecture and construction, textiles, heat exchangers, air conditioning circuits, hygiene-health (hospitals, schools) and food processing.

The achievement of such coatings means, not only a reduction in the problems of corrosion and in health risks, but also a reduction or elimination in the consumption of biocides and toxic industrial detergents.

Various methods and technologies currently exist that enable the obtaining of these biocidal surfaces, amongst which are the incorporation of nanoparticles in organic resins (in ceramic matrixes), as well as the deposition in plasma-vacuum with incorporation of nanoparticles.

An INASMET-Tecnalia research team has led the proposal for the project known as “Development and evaluation of coatings and surface conditions on steel for antibacterial and easy-to-clean properties, DECOBIOF”. The aim is to design, develop and evaluate those surfaces with antibacterial and self-cleaning properties.

Apart from the participation of the Technological Centre, co-ordinator of the project, el the consortium is made up of CORUS UK Limited (UK), the Max Planck Institute (Germany), OCAS-Arce-lor N.V. (Belgium), SIMR (Sweden), ACERINOX (Spain) and the Centro Sviluppo Materiali (Italy).

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
