[G3T]5/Tb3+ based DNA biosensor with target DNA-triggered autocatalytic multi-cycle-amplification and magnetic nanoparticles assisted-background-lowered

General Strategy to Fabricate Electrochemiluminescence Sandwich-Type Nanoimmunosensors Using CdTe@ZnS Quantum Dots as Luminescent Labels and Fe3O4@SiO2 Nanoparticles as Magnetic Separable Scaffolds

“…More recently, magnetic nanomaterials have attracted tremendous interest for their excellent magnetic manipulation and separation ability. Magnetically supported design has been widely popularized in bioanalytical studies, encompassing microRNA recognition, t-DNA detection, separation and detection of bacteria, immunoassay, ,, and so on. As a good biological carrier, Fe 3 O 4 nanoparticles have some attractive features, such as large specific surface area for loading more biomolecules and good magnetic performance for facilitating simple separation.…”
