Biologists know that molecular motors such as actin, myosin, and dynein are instrumental in the functioning of microtubules and microfilaments, the fundamental structures of the cell buttressing its architecture. Just as many organelles utilize motor molecule receptors to move themselves along the filaments of the cell, future medical 'nanobots' could also function more efficiently with motor molecule receptors and thus take advantage of the cell's natural transportation system in order to achieve its programmed goals!
