'One-pot' CRISPR platform delivers lab-like sensitivity in 30 minutes for at-home testing
A research team from The Hong Kong University of Science and Technology (HKUST) has developed an innovative "one-pot" testing platform, known as TEMPO, that could transform highly sensitive nucleic acid testing from a laboratory-based procedure into a simple, single-step test that can be performed at home. With a single reaction tube, users can obtain results comparable to those of professional…
Researchers at The Hong Kong University of Science and Technology have created a novel one-pot CRISPR diagnostic platform called TEMPO, which could revolutionize nucleic acid testing. This platform allows for highly sensitive nucleic acid detection within a single-step procedure that can be performed in 30 minutes using just one reaction tube.
TEMPO integrates nucleic acid amplification and CRISPR-based detection into a single process, overcoming the challenges of traditional multi-step testing methods. The key to TEMPO's success lies in its use of thermodynamically engineered DNA primers, which control the timing of reactions through a precise sequence. These primers ensure that CRISPR enzymes are activated in the correct order, leading to rapid and accurate results.
TEMPO has been tested on various viral infections, such as influenza, COVID-19, and HIV, and has demonstrated attomolar sensitivity, comparable to gold-standard laboratory methods. This breakthrough platform could enable at-home and point-of-care testing, making it easier to detect and respond to infectious diseases and genetic conditions.
