Key Points

The research aims to develop a highly specific method for detecting scandium ions in rare earth elements using a novel biosensor platform.
Utilized a DNA-functionalized silica nanowire-filled micropipette for sensitive detection.
Employed EDTA to minimize interference from coexisting heavy rare earth elements.
Conducted tests in aqueous environments to assess stability and reliability.
The platform shows high selectivity for Sc3+ with significant interference suppression from other rare earth elements.
Demonstrated good stability and repeatability under test conditions.

Implication

Experimental platform detects scandium in rare earth elements, indicating potential for environmental monitoring.
