MICROMEM TECHNOLOGIES INC. ANNOUNCES MANUFACTURING OF NANOPARTICLE DETECTION PLATFORM

Micromem Technologies Inc., through its wholly owned subsidiary Micromem Applied Sensor Technologies Inc. (MAST), has begun manufacturing for client orders its nanoparticle detection platform. This patented detector, developed by MAST, includes a magnetic nanosieve mechanism designed to capture, from a flowing stream of oil, gas or other fluids, 20-nanometre magnetic nanoparticles on a target that is illuminated by a laser. Using patented resonance wave technology, the concentration of the particles is measured to a repeatable accuracy of better than one part per billion. MAST has functionalized chemically the surfaces of the magnetic nanoparticles so as to respond to specific wavelengths of the laser, and the company's technology is unaffected by the opaque nature of oil and gas streams.

The detector was originally contracted by and designed for the International Oil Company for use in waterflood oil well production. It has also gained traction in interwell tracer studies and most recently in environmental applications of tracking carcinogenic chemicals in groundwater. The company maintains intellectual property (IP) control of the detector. The present system is designed for two modes in a lab environment: one, a cuvette mode where a small sample from a core flood analyzer effluent stream and the like can be rapidly evaluated for presence of nanoparticles; and the other, a powerful method of operation that allows for a flow-through mechanism from larger field samples. This product was designed for clients that are investigating the growing use of nanoparticles to help solve critical process and environmental problems. Also, MAST is expanding the functionality of this product by converting it for hazardous environments including direct measurement in real time on producing oil well sample lines.

We seek Safe Harbor.
