Professor Gabby Sarusi of Ben-Gurion University of the Negev has evolved and is currently validating a test that identifies carriers of the COVID-19 virus in less than a minute with more than 90% accuracy and at a particularly lower price than any other method available. . Array clinical trials conducted in collaboration with the Ministry of Defense on more than 120 Israelis had a success rate of more than 90% compared to polymerase chain reaction (PCR) tests. Ongoing trials will seek to determine whether control can identify the express level of COVID-19 infection and its presence.
From the start of testing, we obtained statistically significant results, consistent with our simulations and PCR tests. “
Professor Sarusi is also Deputy Director of Research at the School of Electrical and Computer Engineering and a member of the Electro-Optical Engineering Unit at BGU.
“We are conducting clinical trials and will compare samples from COVID-19 patients with samples from patients with other illnesses to see if we can identify the other stages of COVID-19 infection,” Sarusi said.
Prof. Sarusi developed his chip as a component of the BGU Coronavirus Working Group, initiated by BGU President Prof. Daniel Chamovitz, to harness the university’s resources and ingenuity to address the myriad facets of the pandemic.
Particles from an undeniable breath test or throat and nose swabs, such as those already used for other tests, are placed on a chip with a dense network of specially designed metamaterial sensors. The formula then analyzes the biological pattern and provides an accurate positive/negative result. Result in a cloud-connected formula in one minute. The point-of-care device automatically saves effects to a database that can be shared through authorities, making it easier than ever to track the evolution of the virus, as well as triage and treat patients.
The new approach is based on the modification of the resonance in the spectral diversity of THz imposed by the coronavirus thanks to the THz spectroscopy performed on the device. This spectral diversity has been used in recent decades for the detection and immediate identification of biological samples.
We wonder, given that this virus is like a nanoparticle or a quantum dot with a diameter of between a hundred nm and 140 nm in terms of length and electrical properties, can we find strategies from the world of physics, photonics, and electrical engineering?I found that the answer is yes, this virus resonates at the THz frequency, and spectroscopy at those frequencies proves it temporarily. “
Each control kit would cost between fifty and a hundred dollars to produce, which is much less than existing laboratory controls. In addition, because the control is electro-optical rather than biochemical in nature, it does not affect environmental issues. that may affect the effects of existing control methods.
Current coronavirus test kits rely on the amplification and identity of viral RNA sequences and rely on expensive biochemical reactions and reagents. In addition, those PCR-based kits take hours, or even days in many cases, to produce effects and require logistically confusing shipping. and handling of sensitive and infectious biological samples.
