'Spermbot' Could Be Used To Fertilize Eggs, Deliver Targeted Medicine In Humans
Dec 13, 2013 15:28 PM E
A "spermbot" created by German scientists could one day be used to fertilize human eggs and to deliver medicine to targeted parts of the body. In a study using bull sperm, scientists were able to trap a sperm in a metal nanotube, which could then be guided to a desired location. A paper on the spermbot appears in the journal Advanced Materials.
