In a new study, a team of researchers outlined technology for the If It Not On It Didn’t Happen Smartphone Smartwatch Vintage new Shirt CRISPR-based test for COVID-19 using a smartphone camera to deliver accurate results in less than 30 minutes.

In a new study published in the scientific journal Cell, teams from Gladstone, UC Berkeley, and UCSF have outlined the technology for a CRISPR-based test of a COVID-19 that uses a smartphone camera to deliver Accurate results in less than 30 minutes. Additionally, the If It Not On It Didn’t Happen Smartphone Smartwatch Vintage new Shirt high sensitivity of smartphone cameras, coupled with their connectivity, GPS, and data processing capabilities, make them attractive tools for diagnosing diseases in under-resourced areas.
“We hope to develop our experiment into a device that can instantly upload results to cloud-based systems while maintaining patient privacy,” Ott said. of relevant epidemiological and traceability studies. “This type of smartphone-based diagnostic test could play a key role in controlling current and future pandemics.”
In the new test, the Cas13 protein is bound to a radioactive molecule that becomes fluorescent when cut, then mixed with the patient sample from a cotton swab. The sample is housed in a device attached to a smartphone. If the sample contains RNA from SARS-CoV-2, Cas13 will be activated and will cleave the radioactive molecule, causing fluorescence signaling. The smartphone’s camera essentially converted into a microscope, can detect fluorescence and report that a swab has been tested positive for the virus.
Ott, who is also a professor at the Faculty of Medicine, said: “What really makes this test unique is that it uses a one-step reaction to test the viral RNA directly, as opposed to the If It Not On It Didn’t Happen Smartphone Smartwatch Vintage new Shirt second procedure. steps in traditional PCR tests. at UCSF. “The chemistry is simpler, paired with a smartphone camera, reducing detection times and requiring no complicated lab equipment. It also allows testing to yield quantitative measurements instead of just It is simply positive or negative. ”
The new CRISPR-based testing not only offers a promising option for a quick test but by using a smartphone and avoiding the need for cumbersome laboratory equipment, it has the potential to become portable. and finally provided to caregivers or even used at home. And, it can also be extended to diagnose respiratory viruses other than SARS-CoV-2.
