New Research Results

Development of a biosensor that can easily detect viruses at very low concentrations

AIST has developed an external force-assisted near-field illumination biosensor (EFA-NI biosensor) that can detect small amounts of bio-substances, including viruses, in contaminant containing samples such as secondary treated sewage water. Magnetic beads and fine particles (polystyrene beads) that scatter light are attached to a target bio-substance, and “moving light spots” are made with external magnetic force and near-field illumination for detection. It is possible to detect bio-substances without removing contaminants using the new “movement” distinction method that was not present in the conventional method. With the goal of preventing infection by highly infectious viruses, AIST researchers aim to improve detection sensitivity.

World’s Highest Output with a High-Frequency Oscillator, the “Spin Torque Oscillator”

AIST has developed a small spin torque oscillator with a practical level of output. The output must be 10 μW for practical use, but has been on the order of 1 μW. AIST increased the magnetoresistance ratio to about twice the present level by inserting a crystalline iron-cobalt alloy layer at the interface between the insulator layer and the iron alloy ferromagnetic layer of the oscillator. AIST also increased the withstand voltage, so that a larger current can be passed through the circuit. Consequently, the output reached 10.1 μW, which is comparable to that of a crystal oscillator.

Spintronics Research Center

Creating innovative green IT based on spintronics

The rapid development of IT society is accompanied with a large increase in the power consumption of electronic devices. To reduce the total power consumption of IT appliances, power consumed during input "standby time" as well as active power have to be significantly reduced. To achieve this, it is essential to develop nonvolatile memory, which retains data even after the power is turned off. We are developing low-power-consuming, high-speed, and highly-reliable nonvolatile memory and spin logic device based on spintronics technology. Moreover, we are also developing novel spintronic devices such as nano-sized microwave oscillator called Spin-Torque Oscillator (STO), high-speed physical number generator named Spin Dice, and spin optical devices.
