A team of researchers has transformed real sperm cells into tiny, magnetically controlled micro-robots to help improve fertility.
This development could open new doors in reproductive medicine, drug delivery, and infertility diagnostics.
The bots can be tracked in real time using X-ray imaging.
Sperm cells are naturally fast, flexible swimmers that can navigate the complex environment of the female reproductive tract making them promising candidates for use in medical micro-robotics.
Sperm cells are nearly impossible to see inside the human body using traditional imaging methods like X-ray.
They’re small, low-density, and nearly transparent to radiation.
Researchers and medical professionals from University of Twente and Radboud University Medical Center both in the Netherlands and Canada’s University of Waterloo coated real sperm cells with magnetic nanoparticles.
This made them visible under X-ray and responsive to external magnetic fields. For the first time, these sperm-based micro-robots can now be tracked and steered inside a life-sized anatomical model.
Once inside, they can potentially deliver drugs to hard-to-reach places such as the uterus or fallopian tubes.
