Observation of human sperm acrosome based on near-field terahertz imaging technique

Abstract

We developed a terahertz scattering-type scanning near-field optical microscopy (THz s-SNOW) to perform imaging tests on the acrosome of sperm. Test results show that the morphology of the whole sperm head could be clearly observed, as well as the outline of the sperm acrosome, which has a clear boundary with the nucleus.
