Detect SARS-CoV-2 virus using Near-infrared spectroscopy – Hefnawi 🦙

A work in-progress that started on 25 March, 2020. Prologue Near-infrared spectroscopy (NIRS) is nothing new, however, it’s a relatively new method deployed in the field of virology. It has been successfully used before to identify HIV-1 and Influenza virus. In addition, it doesn’t require any reagents, enzymes or test kits that take at least an hour to perform the test like the PCR (Polymerase chain reaction) or RT-PCR (Reverse transcription polymerase chain reaction) and in most cases 2+ hours.

It is a very interesting idea. Are you planning to use SpO2 sensors or fNIRS devices? Is it going to work aiming to detect the presence of the virus on the blood torrent ?

hefnawi commented 4 years ago

@faturita thank you. The plan is to use Near-infrared Spectroscopy to detect the biological fingerprint of the SARS-CoV-2 virus. I'm not aiming to do work on blood samples but rather nasal swaps as well as nasopharyngeal culture. I'm currently in the process of choosing which IR emitters to use and whether to proceed with Light-to-Frequency converters versus Ambient Light Sensors (Light-to-Voltage).

Hi all, I'm asking to myself if there's a way to obtain a fingerprint of the cars-cov-2 virus so to be able to assess if there is presence of the virus in rooms so to determine that room in building are virus free ... but at same time I'm asking how to do this with our reagent and or dissolution of sampled material that potentially are contaminated. I thought to use a simple device as Scio NIR if it can be suitable for the purposes - i also got a more professional FTIR machine from perking Elmer at work so can do some comparison with a more accurate device ... ... regards from Milan Italy ...

@teeso thank you for reaching out. The Scio NIR is very interesting, however, it doesn't show the exact sensitivity and range within the required optical window for virus detection. Also, the main goal of this project is to provide an open source alternative that can potentially be deployed across hospitals and other facilities.

The PerkinElmer spectrometer would definitely be a more accurate device and that would be really helpful in comparing results as well as obtaining the fingerprint from the Spectra produced.

I will be glad if we get in touch regarding collaboration on this project as I'm currently testing a number of mini spectrometer sensors and will publish results very soon.

Thanks, Ahmed Hefnawi

Just added a number of updates to the post above, in case someone is following up. Thank you all!

P.S. Please mind the annoying spam on emoji reactions, I reported the case to GitHub but it has not been resolved yet, it's embarrassing to see it so just wanted to hint that it's not me.
