New nanofabrication technologies offer great possibilities for medical applications. After a brief introduction of Nanomedicine and the concept of "Lab on a Chip" a variety of applications of these topics will be presented and the use of nanoparticles for modern medical imaging and targeted drug delivery will be shown. A disposable point-of-care lithium chip, capable of measuring lithium concentrations in blood for manic depressive patients will be treated as well as a fertility chip to measure the sperm motility and concentration in semen. Using precise, pulsed electrical fields, individual cells can be transfected with DNA creating new cell properties. Finally a radically new idea to make a nanopill that can detect cancerous DNA in the intestines using nanowires will be presented.
