Hand-held biosensor makes breast cancer screening fast, affordable, and accurate
https://www.sciencedaily.com/releases/2024/02/240213130400.htm

Summary:
Researchers report successful results from a hand-held breast cancer screening device
that can detect breast cancer biomarkers from a tiny sample of saliva.
Their design uses common components, such as widely available glucose testing strips
and the open-source hardware-software platform Arduino.
A saliva sample is placed on the paper strip, which has been treated with specific
antibodies that interact with the targeted cancer biomarkers.
