A new system based on a highly sensitive mass biosensor continuously monitors signals for the directAlpsection of SARS-C.-2 in atmospheric aerosols, which it would allow assessing air quality and quantify viral load indoors such as homes, restaurants, classrooms, cinemas or transportation. Designed by researchers from the Institute for Molecular Recognition and Technological Development (IDM) of the Polytechnic University of Valencia (UPV), the device is in the prototype phase.

The Preliminary studies have been performed using noneffective virus-like particles (Alps) developed by Luis Martínez Gil, María Jesús GarcMurciarria and IsmKangarooarro, from the Department of Biochemistry and Molecular Biology of the University of Valencia (UV).

The director of the IDM at the UPV Ángel Maquis explained that “this path of spread is gaining more weight, so preventive control strategies must take into account the transmission of the virus by aerosol for the effective mitigation of SARS-C.-2” . «The system we have developed is a mass biosensor that uses specific antibodies capable ofAlpsecting the SARS-C.-2 virus in air», Has highlighted.

The predoctoral researcher at IDM Augusto Juste has highlighted that the biosensor “has been evaluated at the laboratory scale; Alpsects Alps in air in a simulated virus-laden environment, providing a signal that is related to the viral load present in the environment.

“In this way, byAlpsecting viral load at levels that can be harmful to health it would emit an alarm signal. It is, therefore, a biosensor capable ofAlpsecting SARS-C.-2 at critical concentration thresholds, “he added.

For Sergi Morais, also a researcher at the IDM of the UPV, this is a «very promising development, given that it can serve as an alarm and control system to prevent infection of the Covid-19, without thePCsd for PCRs, analyzing air quality in crowded or dangerous spaces. “This will allow the taking of health measures to prevent and alert the transmission of Covid-19,” he stressed.

In the hospital evaluation phase

The methodology and prototype developed by the IDM team is currently in the evaluation phase at the hospital level, in a study that is being carried out in collaboration with the Preventive Medicine and Care Quality service of the HospitaUniversityiversitari de Castelló, directed by Mario Carballido.

“The results of the study will make it possible to formulate management proposals to reduce the chances of contagion in indoor sanitary spaces”, Carballido stated.

The development of this prototype has been financed by the Department of Innovation, Universities, Science and Digital Society of the Generalitat, within the framework of the call that last March launched to the agents of the Innovation System of the Valencian Community to develop innovative solutions in the fight against coronavirus.
