Los Angeles, CA - August 21, 2007 --Material Technologies Inc., (OTCBB: MTTG.OB - News; "MATECH"), an engineering and product/service company specializing in technologies that monitor and measure metal fatigue, was featured in recent issues of Los Angeles Business Journal (August 13) and The Los Angeles Times (August 15).

The newspapers noted that the Minneapolis bridge tragedy has resulted in MATECH being approached by five state departments of transportation (DOTs) with inquiries about the Company's Electrochemical Fatigue Sensor (EFS) that detects growing cracks in metal structures.

"The coverage of our company in Los Angeles Business Journal and The Los Angeles Times reflects the continued concern all of us have about the safety of our nation's bridges," said Robert Bernstein, Chief Executive Officer of Material Technologies. "Media coverage such as this helps to raise awareness of the critical importance of bridge safety and the fact that there is a cost-effective alternative to current inspection methods."

Material Technologies' Electrochemical Fatigue Sensor (EFS) System has the only field-testing device able to find growing cracks in bridges as small as 0.01 inches. It is a nondestructive crack inspection system similar in concept to a medical EKG for the heart, and can be used to determine if actively growing fatigue cracks are present. The cost of the EFS System is competitive with other non-destructive crack-detecting technologies which, unlike the EFS, are not capable of determining whether a crack is growing or not. Moreover, the EFS, when used on repaired fatigue cracks, can also determine whether the repair effectively stopped the crack from further growth.
