A lot of effort has been dedicated during the past decades to the detection of gaseous species. Precise and rapid detection of minute gas concentrations

It is several decades since the speech given by Dr. Feynmann at Caltech in 1959 where he pointed out the possibilities of nanotechology [1]. Since

Corrosion can be defined in a simple way as the reaction of a material with its environment which leads to the consumption of the material

The purpose of this post is to explain in a simple and summarized manner the several existing micro and nanostructures employed to manufacture fibre optic

 In this post, some basic concepts about optical fiber refractometers will be briefly explained, including their function, the different existing types and some of the main

This post explores the implementation of a quality detector based on spectroscopy for raw materials in the agri-food industry and agriculture. Here, the use of

 Do you remember this dress picture (Figure 1)? It was posted and went viral in 2015, dividing the world and taking over all our feeds

In this post we will describe the optical techniques based on resonances that can be used for biosensor interrogation apart from the ones seen in the

In this post we will continue explaining some important concepts associated with biosensors (see also our previous post about biosensors), such as the specificity, the

In this post we will briefly describe some of the main optical techniques applied for biosensors interrogation but first it is important to clarify what
