Final COMMON SENSE meeting and public event: Next generation sensors for ocean observation.
On Friday, January 27, there will be a public and free event to present the final results of the COMMON SENSE project on “Demonstration of next generation sensors for advanced real-time ocean observation“.
This event will closure the COMMON SENSE project, in which the NN group has actively participated in the development of electrochemical sensors that are able to detect different heavy metals simultaneously.
- Date and time:
Friday, January 27, from 9 am to 5 pm - Location:
Fundació Navegació Oceànica Barcelona (FNOB)
1 Moll de Llevant, 08039 Barcelona (View Map)
Martí Gich and Anna Roig will participate in a previous meeting on Thursday, with the project team, and on Friday on the public event.
Professionals working in the marine environment and citizens curious about the status of our oceans are invited!
The COMMON SENSE project is creating prototypes of next generation in-situ marine sensors to deliver vital information about the oceans. The project directly responds to the requirement for integrated and effective data acquisition systems by developing innovative sensors that will contribute to our understanding of how the marine environment functions. In doing so, COMMON SENSE results can support the implementation of European Union marine policies such as the Marine Strategy Framework Directive (MSFD) and the Common Fisheries Policy (CFP).
As the COMMON SENSE project comes to a successful conclusion, the results will be presented at this final workshop, along with a demonstration of the novel sensors developed and tested during the project.
The COMMON SENSE sensors need less human operation and intervention than current technologies and create standardised data on eutrophication, underwater noise, heavy metals, and marine litter, with a focus on microplastics. Other important parameters considered are temperature, pressure, pH and pCO2.

Martí Gich at the COMMON SENSE 36 Month meeting in Sardinia
Martí Gich is at the COMMON SENSE 36 Month meeting, which will take place in Oristano, Sardinia, on September 29-30. The COMMON SENSE project aims at developing low cost sensors that will revolutionise current marine monitoring strategies.
Please enjoy this short video featuring field testing of COMMON SENSE sensors, which have been testes in various cruises throughout the past year:

New paper accepted in Microchimica Acta
The work has resulted from a collaboration between the ICMAB, the CNM and the company Dropsens.
Screen-printed electrodes made of a bismuth nanoparticle porous carbon nanocomposite material applied to the detection of heavy metals (Pengfei Niu, César Fernández-Sánchez,* Martí Gich,* Carla Navarro-Hernández, Pablo Fanjul-Bolado, and Anna Roig, Microchimica Acta, , Volume 183, Issue 2, pp 617-623).
This work reports on the simplified fabrication and on the characterization of bismuth-based screen-printed electrodes (SPEs) for use in heavy metal detection.
A nanocomposite consisting of bismuth nanoparticles and amorphous carbon was synthesized by a combined one-step sol-gel and pyrolysis process and milled down to a specific particle size distribution as required for the preparation of an ink formulation to be used in screen printing. The resulting electrochemical devices were applied to the detection of Pb(II) and Cd(II) ions in water samples.
The porous structure of carbon and the high surface area of the bismuth nanoparticles allow for the detection of Pb(II) and Cd(II) at concentration levels below 4 ppb. The application of the SPEs was demonstrated by quantifying these ions in tap drinking water and wastewater collected from an influent of an urban wastewater treatment plant.

Electroanalytical Assessment of Heavy Metals in Waters with Bismuth Nanoparticle-Porous Carbon Paste Electrodes
The final version of the paper in Electrochimica Acta is on-line . It will be published in the journal in May. You can download it from the link. http://authors.elsevier.com/a/1QjGc_JcNCuYR The journal provides free access to the article for almost two months and the article can also be shared during this time.
Highlights
- •A bismuth carbon nanocomposite material prepared by a one-pot sol-gel process.
- •Application to the fabrication of a sensor for heavy metal detection in waters.
- •Cd, Pb and Ni were measured at concentration levels below the MAC-EQS set by the EU.
- •Thorough assessment of the sensor performance in water samples of different origin.
Welcome to Pengfei Niu!
Pengfei is a Master Graduate in Polymer Composites from the Univesity of Sichuan in Chengdu (China). He will spend 3 years with us thanks to the financial support of the China Scholarship Council to complete a Ph.D. working in the development of nanocomposite sensors prepared by Sol-Gel chemistry. We wish him plenty of scientific and personal success.
