Toronto, Ontario, M5G 2E4

Press release date: April 21, 2014

TORONTO and NEW YORK - Micromem Technologies Inc. (the "Company") (CSE:MRM) (OTCBB:MMTIF) through its wholly owned subsidiary Micromem Applied Sensor Technologies Inc. (MAST), announces manufacturing has begun for client orders of our nanoparticle detection platform (the "Detector").

This patented Detector developed by MAST, includes a magnetic nano-sieve mechanism designed to capture, from a flowing stream of oil, gas or other fluids, 20 nanometer 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 1 part per billion. MAST has functionalized chemically the surfaces of the magnetic nanoparticles so as to respond to specific wavelengths of the laser and our 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 water flood 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.
