Dermisonics, Inc. Disputes Claims Made By Sontra Medical In Sontra’s Press Release Dated February 1, 2006

WEST CONSHOHOCKEN, Pa., Feb. 1 /PRNewswire-FirstCall/ -- Dermisonics, Inc. disputes allegations made by Sontra Medical Corp. in their press release of February 1, 2006. Dermisonics does not intend to infringe the intellectual property rights of Sontra, or any other party, now or in the future. Accordingly, Dermisonics is investigating Sontra’s allegations and has referred this matter to its patent counsel.

In a September 2005 letter to Dermisonics, Sontra’s counsel stated, “Sontra believes it would be fruitful for Sontra and Dermisonics to discuss a possible business venture.” In furtherance of that possibility, in December 2005 Dermisonics and Sontra entered into a mutual confidentiality agreement for the purpose of reviewing the compatibility of each other’s technology and applications. It was Dermisonics’ understanding that these discussions would continue in early 2006.

Dermisonics looks forward to working with any party that can advance its technologies to commercialization.

About Dermisonics, Inc.

Dermisonics is an intellectual property company and advanced technology incubator that is primarily focused on the ongoing development, testing and eventual commercialization of a transdermal patch that has been designed to facilitate the efficient and needle-free delivery of drugs with large molecular structures into the bloodstream. Its breakthrough system, called the U-Strip, is based on a radical integration of microelectronics and ultrasonic science with a product-carrying patch, and represents a quantum leap in non- invasive, transdermal delivery technology. Tests have shown that this system facilitates the transdermal delivery of insulin as well as potentially at least 175 other existing drugs that at present cannot be effectively delivered through the pores of the skin using conventionally available transdermal technology due to their large molecular size. The Company has also developed other portable ultrasonic systems for applications in the medical (Antiseptic Wand) and skin care (U-Wand) fields.
