With the continuing need for very small devices in therapeutic applications, there is an increasing demand for the development of nanoparticles that can deliver and transport drugs to target cells in the human body. Researchers recently made nanoparticles that under the right conditions, self-assemble, trapping complementary guest molecules within their structure. Like tiny submarines, these nanocarriers can navigate in the watery environment surrounding cells and transport their guest molecules through the membrane of living cells to deliver their cargo.
