Infectious and respiratory infections, in particular, are the leading cause of death worldwide. There is therefore an urgent need for rapid, large-scale diagnostic tools that can detect these diseases early, which currently do not exist. To address these issues, a McGill University bioengineering professor said: Sarah Mahsidhas developed an all-in-one detection platform (QolorEX) that can deliver test results in just 13 minutes.
For use in hospitals, schools, airports, and other places where people gather, the test takes a saliva sample (no cotton swabs required), transfers it to a microfluidic device, and uses machine learning to automatically take microscopic images. To do. sample. These images are sent to a mobile phone application where the data is decoded into test results.
“With more pandemics likely to occur in the future, our lab will be a portable, low-cost laboratory with actionable clinical results that can be used in low-resource, home, or communal settings. We aim to build cost technology,” Mahashid and his students say.Doctoral Candidates Tamer Abdel Fattah and Mahasa Jalali, co-authors of a recently published paper natural nanotechnology
“This platform has been shown to show 95% accuracy, comparable to quantitative PCR, for COVID-19 testing using saliva samples, making it an ideal platform for monitoring new viral infections, variants, and even bacteria. It can be a valuable tool: accessibility can increase the number of tests performed, potentially leading to earlier diagnosis, saving lives and curbing the spread of respiratory disease worldwide. It’s possible,” added Mahashid, who is also chairman of Canada’s research committee for nano-biosensing devices.
QolorEX is led by Dr. Chen Liang of Jewish General Hospital, Prof. Silvia Vidal of McGill University, and Dr. Dao Nguyen of RI-MUHC. Thesis is Nanotechnology in nature.
