This invention belongs to the field of immunoassay and biosensing technology, and discloses a method for preparing a ratiometric ECL biosensor based on Eu / Tb-Lu MOGs. Using Eu / Tb-Lu MOGs as the luminescent material and H3-tctpy and luminol as ligands, a single-luminescent material with dual ECL emission is synthesized. Lanthanide ions provide the cathode ECL emission, enhanced by the antenna effect and Tb→Eu energy transfer; the anode emits light from luminol using dissolved oxygen in water, requiring only the addition of K2S2O8 as a single co-reactant, resulting in fewer side reactions and a stable signal. The dual-potential ratiometric sensing utilizes the dual ECL signal for self-calibration, improving anti-interference and reliability; the single-luminescent dual-potential system achieves synchronous anode / cathode luminescence, simplifying the system and improving detection accuracy. By detecting changes in the ECL signal of different concentrations of analytes, the detection of microRNA-126 is achieved.

A low formation voltage NVM device is provided by forming a pair of sacrificial conductive pads on an interconnect dielectric material layer that is embedded with a pair of second conductive structures and a patterned material stack. One of the sacrificial conductive pads has a first region and contacts a surface of one of the second conductive structures that contacts a surface of an underlying first conductive structure, and the other of the sacrificial conductive pads has a second region different from the first region and contacts a surface of the other of the second conductive structures that contacts a surface of a top electrode of the patterned material stack. A plasma treatment is performed to induce an antenna effect and convert a dielectric switching material of the patterned material stack into a conductive filament. After the plasma treatment, the pair of sacrificial conductive pads is removed.
