Summary

Story summary

Researchers at Université de Montréal developed a DNA-based assay to monitor drugs in blood, delivering results in about five minutes with an inexpensive reader.
The method relies on signaling cascades in which specific DNA molecules interact with drug targets to generate an electrochemical current.
The technology could enable personalized treatments and broaden access to therapeutic drug monitoring.
The findings were published in the Journal of the American Chemical Society (JACS).
