Highly sensitive monoclonal antibodies for a new biosensor for hormones detection in fertility treatments

Nb4D research group and NANBIOSIS U2 Custom Antibody Service (CAbS) of CIBER-BBN at the IQAC-CSIC, together with the company Droplite Technologies have obtained a Retos-Collaboration project funded by the Ministry of Science and Innovation, for the development of a biosensor for detection and rapid quantification of hormones, linked to in-vitro fertility treatments.

NANBIOSIS U2 CAbS will be responsible for the production of highly sensitive monoclonal antibodies, counting on the experience in this field of Juan Pablo Salvador, project coordinator, Núria Pascual and Mª Pilar Marco.

The measurement of the hormone estradiol is a key indicator, both of maturity and of the degree of ovarian stimulation, very important in a successful fertilization process. But there are no tools that allow accurate and sensitive monitoring.

Thus, the consortium formed by Nb4D-Droplite proposes as a solution a new device to perform the control and quantification of hormones, in particular estradiol, in less than 30 minutes, without the need for a central laboratory and only using a drop of blood, which is obtained simply by pricking the patient’s finger.

With funding of € 388,531, the project strategy consists of a transversal collaboration between the Droplite company and the CIBER-BBN research center, through the Nb4D group, supported by the Hospital Clínic de Barcelona, ​​which allows a continuous evaluation and optimization of the prototype based on the exchange of experiences and knowledge.

On the other hand, Droplite, led by its co-founders André Guedes and Rafael Porcar, contributes its experience in the development of an optical detection system based on nanotechnology, which will allow to detect and monitor, automatically and quantitatively, different markers and provide results in just 10 minutes. Droplite is dedicated to the biotechnology sector that emerged as a spin-off of the Institute of Photonic Sciences (ICFO)

The call Retos Colaboración

The aid of this call, managed by the Ministry of Science and Innovation and the State Research Agency, aims to support experimental development projects in cooperation between companies and research organizations, in order to promote the development of new technologies, business application of new ideas and techniques, and contribute to the creation of new products and services.

Laura Lechuga talks about CONVAT, the project for a faster and cheaper diagnose of COVID-19

Prof. Laura M. Lechuga, Scientific Director of NANBIOSIS Unit 4 Biodeposition and Biodetection Unit (from CIBER-BBN and ICN2-CSCIC) has been today interview by Cadena Ser Radio in the program “Hoy por Hoy”

The interview can be listened in the following podcast, begining at 44 minute.

‘Convat’ is a nanotechnological device with biosensors capable of determining in less than half an hour the presence of coronavirus in a person. A sample saliva is deposited on a nanochip three centimeters long. If the saliva contains the virus, it will bind to antibodies located on the nanochip. A beam of light will be passed through the device so that the light will change if it encounters the virus and antibody in its path. The light will be analyzed automatically and the result will be transmitted to a smartphone or tablet. In less than 30 minutes a positive or negative result would be obtained and, in case of detecting the presence of the virus, in another 30 minutes at most the reconfirmation would be obtained. It is not intended for domestic use, but neither will a specialist technician be needed and it could be carried out in a massive way.

Simpler, cheaper and easier than current methods, this rapid diagnostic kit will not be ready for the first wave of the coronavirus, but it can be useful to detect it later if this virus is here to stay.

Yesterday, Laura Lechuga was also invited to explain the CONVAT project to the spanish television programe “A partir de hoy“.

Photonic Label-Free Biosensors for Real-Time Analysis of Untreated Clinical and Environmental Samples

The biannual Conference on Bioanalytical Sensors will take place in June 24 – 29 in Newport,  US, with the theme “State-of-the-Art Bioanalytical Sensing Approaches for Healthcare and Therapeutics, Forensics, and Visualization of Living Systems”.

Prof. Laura M. LechugaScientific Director of NANBIOSIS  U4. Biodeposition and Biodetection Unit: is giving a Conference on “Photonic label-free biosensors for real-time analysis of untreated clinical and environmental samples

The focus of this meeting is on the development of new bioanalytical tools that provide highly specific and quantitative molecular data of biological systems leading to real applications to the clinic. Specific topics will include micro- and nanofluidics systems, nanomaterials, in vitro and in vivo sensing and imaging, while also covering instrumental techniques, and real world detection/diagnosis.
