In situ measurements. The long-term perspective of VolThinSens 

01.05.2019

One of the strengths of all the electrochemical sensors relates with its suitability to accomplish decentralised measurements. This means that "THE SENSOR GOES TO THE SAMPLE" rather than bringing the sample to the laboratory in where it is analyzed. This is a feature that not all the analytical techniques provide because of obvious reasons of portability. Indeed, this unique characteristic was one of the reasons for me to be attracted by the electrochemical sensors since I was a bachelor student ;)

During my postdoctoral training at the University of Geneva (2014-2017), I was very lucky to be involved in the SCHeMA project funded by the European Commission. Owing to my work there, I learnt many things regarding the managing of an EU project at the side of reporting, organizing internal meetings and communication strategies, among others. But for me, the most exciting part was that involving the development of a submersible probe for the detection of species relevant to the C and N cycles as well as salinity in seawater and natural waters. Crazy years plenty of research at the laboratory scale, meetings at Idronaut (Italy) and long field campaigns sometimes without time for sleeping or eating...SCIENCE NEVER SLEEPS and the happiness of obtaining real time results in the middle of the sea is priceless.

Holding a MSCA-IF fellowship is unique for many different reasons and one of them is the opportunity to collaborate in side projects in the host group apart from your main research line. In my case, in the Crespo Group I am involved in the digitalization of the body status through wearable devices. Specifically, we have developed microneedle-based potentiometric sensors for the transdermal detection of potassium in interstitial fluid and wearable potentiometric sensors for the characterization of the sweat composition.

What is interesting in these devices is its long-term perspective. Whether the laboratory prototypes are massively validated and evolve to more advanced devices, they will be used to gather unique information in real time that will help in clinical decision-making processes as well as the design of personalized strategies for sport practice.

VolThinSens cares about the decentralized acquisition of analytical data and works from a fundamental point of view to finally apply the developed sensors to two different cases within EU priorities "citizens' welfare" and "protecting nature". Thus, VolThinSens aims at enhancing EU excellence and competitiveness in pharmacological/clinical control as well as water issues through the provision of trustable relevant data in a long-term perspective.

Hopefully, new and exciting results will be published soon ;)
