High quality antibodies for very challenging projects

Researchers of Nb4D group – Unit 2 of the ICTS NANBIOSIS (led by Pilar Marco, from CIBER-BBN and the IQAC-CSIC) have participated in Expoquimia 2021, the International Chemistry Meeting, which took place from 14 to September 17 at the Fira de Barcelona.

The researchers presented their work in several projects: the FoodSmartPhone project (MSCA-ITN-720325 action), the QS4CF (RTI2018-096278-B-C21), the QS-Motion (TV32018-201825-30-31) and on the PoC4CoV project (PIE-202050E090; PTI Salud Global, CSIC).

Research at the FoodSmartPhone(MSCA-ITN-720325 action) is focus on developing devices for the monitoring of contaminants of interest in food safety through the use of mobile phones. The production of the necessary antibodies for the detection of antibiotics and pesticides has been carried out by NANBIOSIS U2 Custom Antibody Service (CAbS). These are very specific monoclonal antibodies against pesticides, used by researchers Klaudia Kopper and Julian Guercetti to bind them to the functionalized surface and implemented in plasmonic detection sensors for antibiotics in milk and electrochemical biosensors for the detection of pesticides in cereals.

The scientific activity within the QS4CF (RTI2018-096278-B-C21) and QS-Motion (TV32018-201825-30-31) is focused on the Quorum Sensing communication system as an strategy to develop more efficient and specific diagnostic tools and therapeutic approaches to diagnose and treat P. aeruginosa and S. aureus infections.

The PoC4CoV project (PTI Salud Global, CSIC) seeks a comprehensive approach to diagnose COVID-19 developing devices to detect genetic material and proteins of the SARS-CoV2 virus, but also the response of the host against the infection. High quality antibodies against SARS-CoV-2 structural proteins (spike and nucleocapsid) have been produced by CAbS at NANBIOSIS

The camera flash is able to excite the functionalized surface of the chip and generate the specific response to the contaminant. This signal is picked up by the mobile through a Bluetooth connection and quantified.

The CSIC Global Health Platform, launched in March 2020, coordinates more than 100 projects to unravel the new coronavirus and seek medium and long-term solutions. The platform has mobilized and coordinates more than 300 research groups from more than 90 CSIC centers, out of a total of 120, in six work topics, which try to cover all aspects of the pandemic with an interdisciplinary approach: prevention, prevention, disease, containment and diagnosis, treatment and vaccines, social impact, and communication.
The platform has coordinated 100 research projects and actions, ranging from the development of antivirals and anti-inflammatory treatments, the monitoring of transmission, the study of the virus genome and the impact of mutations, the genetics of patients, their immune response to infection and vaccination, up to the launch of systems for diagnosis and containment of the virus.
The platform has also included studies carried out on the social perception of the measures, especially on the impact on nursing homes.

The Global Health platform has become a stable structure for scientific cooperation, as well as for the generation of patented technologies. Its consolidation, reinforcing its structure and coordination mechanisms, in particular the link with the clinical sector, prepares the body to face new challenges and opportunities, and for the development of initiatives with companies in Spain, necessary to configure a response to this and future pandemics.

NANBIOSIS Unit 2 obtains the Biosafety Level 2 Accreditation

The laboratory of NANBIOSIS Unit 2 from IQAC-CSIC and CIBER-BBN has obtained the biosafety level 2 accreditation, which allows the laboratory to work with biological agents classified in the risk group 2.

Biological containment level 2 (NBS2) laboratories are generally required to work with any derivative of human blood or other primates, body fluids (especially when they are visibly contaminated with blood), cell lines, or tissues in which has uncertainty about the presence of an infectious agent.

Also, the group participates in the COVID project “Point-of-care tests for the rapid detection of SARS-CoV-2 (POC4CoV)”, funded by the CSIC. This project involves the handling of swabs and serum samples from both positive and negative SARS-CoV-2 patients. Lluïsa Vilaplana, member of research group Nb4D of CIBER-BBN and IQAC-CSIC, led by Dra. M. Pilar Marco, wich Coordinates NANBIOSIS U2, has coordinated the process to obtain the accreditation.

The laboratory has an antechamber or clean locker room, a card-controlled entry system and a space for the storage of materials and reagents. It has also an independent air conditioning system, a specific air renewal system and a biosafety cabin type 2A, with HEPA filter. In addition, it is equipped with a suitable lighting system, an emergency lighting system and a large observation peephole on the door.

In addition to this specific equipment, the laboratory is equipped with an inverted microscope, centrifuge, thermostatic bath, stirrers, incubators, refrigerator and autoclave for sterilization and waste management.

The Nanobiotechnology for Diagnosis (Nb4D) research group , focus the research on the development of biomarkers for the diagnosis of infectious diseases. Nowadays, the group participates in five research projects related to this topic. These projects involve working with clinical samples for the detection of the pathogens Pseudomonas aeruginosa (Gram – type bacteria) and Staphylococcus aureus (Gram + type bacteria), both classified in risk group 2.

Pilar Marco explains on TV her group’s research against Covid-19 pandemic

M.-Pilar Marco, Scientific Director of NANBIOSIS Unit 2 Custom Antibody Service (CAbS) has been interviewed on Spanish TV (RTVE) to talk about her research against the Covid-19 pandemic in the frame of the CSIC POC4CoV project, for the development of new and rapid diagnostic tools.

Nb4D group of CIBER-BBN and IQAC-CSIC, led by Prof. Marco is working on the development of tests to increase the efficiency and speed of diagnosis of the methods currently on the market.

According to Pilar Marco, the new strategy of the project differs basically in two fundamental aspects: on the one hand the technology, which is based on the current knowledge of some of the CSIC’s research groups in micro and nano techno technology and, on the other hand, in the selection strategy of the antigens that will produce a more specific and sensitive response to the or SARS-COV-2.

The time required to develop these tests is relatively short since researchers have the advantage of having detection technologies already developed and tested in other types of projects, but even so, these tests need between 6 and 8 months of development to obtain the first prototypes that, obviously, will have to be validated so that they can be made available in the market in a safely. Therefore the new tests will help us to be much better prepared before the new waves of the pandemic expected by the epidemiologists.

The interview can be watched in the following link (0:41:50)

NANBIOSIS U2, U3 & U29 participate in the POC4CoV project to develop diagnostic technologies for SARS-COV-2

The Spanish Higher Council for Scientific Research (CSIC) will finance the project Point-of-care tests for the rapid detection of SARS-CoV-2 (POC4CoV), whose objective is to have effective diagnostic technologies for Covid-19. The Institute of Microelectronics of Barcelona (IMB-CNM-CSIC), the Institute of Advanced Chemistry of Catalonia (IQAC-CSIC) and the Institute of Materials Science of Aragon (ICMA) participate in it.

The POC4CoV project aims to develop Point-of-Care (POC) devices for the in vitro diagnosis of SARS-COV-2 infection quickly and reliably, thanks to the use of multiplexed systems and the use of particular biomolecular probes. To do this, POC technological platforms will be used in combination with specific capture biomolecules and nanobiotechnological probes (enzyme bioconjugates and biofunctional plasmonic and magnetic nanoparticles), which will allow the simultaneous detection of different biomarkers (viral RNA and antigens, IgM and IgG) related to Covid-19 disease. The biomolecular complexes will be collected at specific points on the devices where the electrochemical or optical signals will be recorded.

The developed POC platforms will undergo analytical and clinical validation in a clinical setting.

Three units of NANBIOSIS (form CIBER-BBN and IQAC-CSIC) will will take an active participation in the project.

NANBIOSIS Unit 2 Custom Antibody Service (CAbS), will produce antibodies against the Spike protein and other virus proteins, trying to maximize the recognition of those epitopes that differentiate SARS-CoV-2 from other Coronaviruses

NANBIOSIS Unit 3 Synthesis of Peptides Unit will synthesize peptidic sequences that will allow to identify towards which epitopes the immune response is directed, which will allow to develop more specific diagnostic methods.

NANBIOSIS Unit 29 Oligonucleotide Synthesis Platform (OSP) has designed probes with oligonucleotide sequences that will allow the capture of viral RNA through the formation of high affinity triplex complexes
