Enhancing Therapeutic Delivery Using Micro- and Nanorobots.

"The traditional way of delivering drugs has a very low efficiency. For instance, with solid tumors, drug delivery efficiency is reported to be lower than 1% [1], which means that 99% of the drug is elsewhere in the body causing side effects instead of actually fighting the cancer. This is where micro- and nanorobots can come into play, because they can swim or otherwise move to the target location in a controllable way. This is the hope."-Tian Qiu, Ph.D., biomedical robotics developer.
