Tampon-Like Foam Device for Dual-Purpose Contraception

Giovanni Pauletti of the University of Cincinnati in the U.S. will develop and test a tampon-like, biodegradable foam device made from polymers that contain a safe spermicide and a microbicide. The device can be self-administered by women and quickly reacts to vaginal fluids to convert to a hydrogel that creates a physical and chemical barrier to sperm and HIV and other virions.
