Team of researchers from Institute for Integrative Nanosciences at IFW Dresden, Germany, have developed spermbots, a tiny metal helix that attaches to individual sperm cells and help them move. Fit over sperm cells to treat infertility, team used 3D laser lithography to create the helix.

During the recent project, where researchers from Northwestern University were implanting a 3D Printed Working Ovary in mouse, Adam Jakus, a postdoctoral fellow in Professor Ramille Shah’s lab, was preparing 3D printing ink made from ovarian cells which he accidentally spilled, ultimately leading to discovery of “Tissue Paper”. This “Tissue Paper” can be used to restore normal hormone function to young cancer patients and restored fertility to women. Research team is planning to use it to repair organs and bioactive Band-Aid that would facilitate the healing of a wound.
