title: Label-free fluorescent DNA sensor for the detection of silver ions based on molecular light switch Ru complex and unmodified quantum dots.
abstract: Using molecular light switch Ru complex Ru(bpy)(2)(dppz)(2+) and CdTe quantum dots (QDs), we have designed a label-free DNA fluorescent sensor for the detection of Ag(+) in aqueous solution.
