Abstract
The present invention provides the methods and composition useful as a contraceptive by preventing motile sperm from reaching a mature ovum, thereby blocking fertilization and preventing pregnancy. The contraceptive is comprised of halogen functionalized fullerene nanoparticles (halo fullerenes) and chemotactic stimulants that act synergistically to divert, incapacitate and ultimately rupture spermatozoa to avert fertilization. When applied vaginally prior to coitus, the suspension is activated by exposure to spermatozoa upon insemination. Notably, non-spermatozoa cells are unaffected by the pH-neutral suspension; however, closer to the same scale, microbes are susceptible to its inherent biocidal properties. Following application and coitus, the contraceptive evacuates naturally, along with seminal and vaginal fluids thereafter.
