Taken From: The use of nanocrystals in biological detecion, Paul Alivisatos Nanoscale Cantilevers Cantilevers can be used as detectors of molecules. In this example specific molecules are attached to the cantilevers. The molecules selected are

molecules that will bind to a specific molecule. When that molecule binds to the cantilever it changes the physical properties of the cantilever and that change can be detected. Reference: Arun Majumdar, University of

California at Berkeley A team at the California Institute of Technology is using tiny cantilevers to probe molecular bonds. Nanomedicine - Conclusion Nanotechnology will radically change the way we diagnose, treat and prevent cancer Nanomedicine for cancer has the ability to

improve health care dramatically Current research is mostly in diagnostic tools, although there are many other application of nanomaterials in medicine There are still lots of advances needed to improve Nanomedicine
