Currently, one of the six current "Grand Challenges" of the University of Sydney Nano Institute is to develop nanorobotics for health, a key aspect of which is a “ nanoscale parts foundry ” that can produce nanoscale Brownian motors for “ active transport around the body”. The Institute predicts that among the implications of this research is a "paradigm shift" in healthcare "away from the " break-fix " model to a focus on prevention and early intervention," such as in the case with heart disease :
