    Scientists take challenge of developing functional microdevices for direct access to the brain, spinal cord, eye and other delicate parts of human body. A tiny robot that gets into the human body through the simple medical injection and, passing healthy organs, finds and treats directly the goal – a non-operable tumor… Doesn’t it sound at least like science-fiction? To make it real, a growing number of researchers are now working towards this direction with the prospect of transforming many aspects of healthcare and bioengineering in the nearest future. What makes it not so easy are unique challenges pertaining to design, fabrication and encoding functionality in producing functional microdevices.

  • Physics That Gets Under Your Skin

    Due to modern advances in medicine ever smaller objects are moved through the human body: nanotherapeutics, micro-implants, mini-catheters and tiny medical instruments. The next generation of minimally invasive microsurgery will enable small micro robots to move with their own drive through the body and through the tissue to transport substances and micro-objects. Therefore, new methods must be developed to locate these micro-objects precisely and to monitor their movement. Conventional methods such as ultrasound, X-ray or magnetic resonance imaging (MRI) fail either due to insufficient resolution or due to long-term damage from radioactivity or high magnetic fields.
