A Zeolite Hydrogel 'Nano-Mop' For Contraception

Benson Wamalwa of the University of Nairobi in Kenya will develop and test a vaginal gel that contains zeolite nanoparticles which soak up the fructose present in semen. By "mopping" up the fructose, this gel will rob sperm of the energy needed for motility. If successful, the gel could be used as an inexpensive, non-hormonal contraceptive.
