LLAVOR Project was awarded to the Group NN

PLANT HEALING, a project lead by Dr. Anna Laromaine from the Group Nanoparticles and Nanocomposites at the Institut of Materials Science in Barcelona (ICMAB) and in collaboration with the Group of Bacterial pathogens and plant cell death from the Center for Research in Agricultural Genomics (CRAG), was awarded by Els Fons Europeus de Desenvolupament Regional i el Departament d’Empresa i Coneixement de la Generalitat de Catalunya with a grant of 20.000€. The PLANT HEALING 2016 LLAVOR 00052 project will work to offer a novel material that could be implemented in current grafting protocols with no extra time or effort to significantly improve graft efficiency. PLANT HEALING will make an agricultural breakthrough, by developing a new nanocomposite material containing silver nanoparticles linked to bacterial nanocellulose.


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.
he 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.
