Nanoplasmonic biosensor device for the monitoring of acenocoumarol therapeutic drug in plasma

As a result of the collaboration carried aout by two units of NANBIOSIS, U4. Biodeposition and Biodetection Unit and U2. Custom Antibody Service (CAbS), it has been developed a compact and simple nanoplasmonic sensing device based on gold nanodisks for the rapid monitoring of acenocoumarol, using highly specific polyclonal antibodies produced against the drug Acenocoumarol (Sintrom®) which implies:

A label-free nanoplasmonic device for the rapid monitoring of acenocoumarol in plasmaD.
Direct quantification in real time requiring low sample volume is achieved.
Non-specific interferences from plasma are minimized using the developed methodology.
Excellent accuracy has been observed measuring blind plasma samples.
Potential to be implemented as a POC device in decentralized settings.

The research details have been published in the article authored by E. CristinaPeláez, M.-CarmenEstevez, AlejandroPortela, J.-PabloSalvador, M.-PilarMarco and Laura M.Lechuga, “Nanoplasmonic biosensor device for the monitoring of acenocoumarol therapeutic drug in plasma, Biosensors and Bioelectronic, 119, 2018, 149-155 – DOI: https://doi.org/10.1016/j.bios.2018.08.011

Interferometric nanoimmunosensor for label-free and real-time monitoring of Irgarol 1051 in seawater

As a result of a collaboration in the context of the EC-FP7 program OCEAN 2013, NANBIOSIS Unit 2 Custom Antibody Service (CAbS) and Unit 4. Biodeposition and Biodetection, the research groups coordinating this NANBIOSIS Units have recently published an article titled “Interferometric nanoimmunosensor for label-free and real-time monitoring of Irgarol 1051 in seawater” in the scientific magzine iosensors and Bioelectronics.

The CIBER-BBN-ICN2 group Nanobiosensors and Bioanalytical Applications, led by Prof. Laura Lechuga has developed the immunosensor that is described in the article using immunoreactive, produced in the group of Nanobiotechnology for Diagnostics Group (Nb4D), led by Prof. Pilar Marco, with the collaboration of CAbS, for Irgarol 1051. This compound is an alguicide used as an additive in the paintings of ships. Over time, the compose is being released into the marine environment causing a risk to the ecosystem and to the health of the population.

In the article, an interferometric nanobiosensor for the specific and label-free detection of the pollutant Irgarol 1051 directly in seawater has been settled. Due to the low molecular weight of Irgarol pollutant and its expected low concentration in seawater, the sensor is based on a competitive inhibition immunoassay. Parameters as surface biofunctionalization, concentration of the selective antibody and regeneration conditions have been carefully evaluated. The optimized immunosensor shows a limit of detection of only 3 ng/L, well below the 16 ng/L set by the EU as the maximum allowable concentration in seawater. It can properly operate during 30 assay-regeneration cycles using the same sensor biosurface and with a time-to-result of only 20 min for each cycle. Moreover, the interferometric nanosensor is able to directly detect low concentrations of Irgarol 1051 in seawater without requiring sample pre-treatments and without showing any background signal due to sea matrix effect.

NANBIOSIS U2 incorporates a new Nitrogen tank to store cells

NANBIOSIS U2. Custom Antibody Service (CAbS), is incorporating new equipment as a result of its participation in the project FICTS1420-27, selected by the MINECO for co-financing by the FEDER Program in ICTS 2014-2020.

Recently the purchase and installation and set-up of a new nitrogen tank to store cells has taken place. The storage of cell lines of monoclonal antibody-producing hybridomas is a process in which the cells are conserved when they are cooled to temperatures typically at -196 ° C in liquid Nitrogen tanks. With temperatures below -130 ° C the activity Biological ceases and storage at these temperatures is vital to keep the material unaltered. The increasing activity of the NANBIOSIS U2 the makes necesary to incorporate a new tank of liquid Nitrogen for the storage of new hybridoma lines.

Agreements signed with MINECO for the allocation of FEDER funds for NANBIOSIS ICTS

In the framework of the FEDER Program in ICTS 2014-2020, several projects related to the ICTS NANBIOSIS have been selected by the MINECO for co-financing with FEDER funds of the European Regional Development Funds program.

An agreement has been signed between MINECO and CIBER (partner of NANBIOSIS for the co-financing of the Project: “Purchase, installation and set-up of production and characterization equipment to complement the Units: U3-Synthesis of Peptides Unit, U18-Nanotoxicology and U20- In Vivo Experimental Platform”. The total budget of the project amounts to € 307,566.16, with 50% financing with FEDER Funds.

Also CSIC (The State Agency Superior Council of Scientific Investigations), institution that houses some of the NANBIOSIS units, as distributed ICTS, has signed an agreement with MINECO for the co-financing of the Project: “Purchase and installation and set-up of equipment and production and characterization laboratories to complement the units U2-Production of antibodies, U4-Biodeposition and biosensing, U6-Processing of biomaterials and U8-Micro, nanotechnology. The total budget of the project amounts to € 312.800,00 €, with 50% financing with FEDER Funds.

These two projects aim to increase the quantity and quality of the services offered by th implied units, with the objetive of positioning them as national and international benchmark in their respective fields of application. As a consequence, an increase in the performance (number of services and number of users) of each unit is expected, especially from companies (pharmaceutical and small biotechnology).

CSIC and CIBER are processing the necessary contracting procedures for the execution of these projects.

Unit 2 of NANBIOSIS participates in the FoodSmartPhone project of Marie Sklodowska Curie.

The Nb4D group of CSIC, coordinator of Unit 2 of NANBIOSIS led by Pilar Marco has joined the consortium for the FoodSmartPhone project funded by the Marie Sklodowska Curie Research Program. The Marie Sklodowska-Curie Actions (MSCA) support training in research and professional development aimed at innovation skills.

The objective of the project is to develop a smartphone-based diagnostic and detection tool for simplified quick pre-selection of food quality and safety parameters. This is because food safety and quality tests are currently inefficient, expensive and ineffective and can not guarantee food safety for all consumers or prevent possible incidents of food fraud.

FoodSmartPhone offers an opportunity for a doctorate that covers all aspects of smartphone-based detection tools, as well as a wealth of scientific knowledge as well as innovation and transfer.

The Nb4D group will act as leader of work package For more information 1 which aims to develop new concepts of ligand binding assay. The group will host two ESRs (Early Stage Researchers) and will also organize training events and an advanced PhD course for the production of haptens and bioreceptors.
