The paper on nanomotors that selectively pick up cancer cells is highlight this week in C&EN (Chemical & Engineering News).
Nanoengineers Joseph Wang and Liangfang Zhang of the University of California, San Diego, and coworkers show that tube-shaped microrockets functionalized with antibodies can cruise through human blood serum.
Video Caption (see below): In the first section of the video, you can see the microrocket (black) selectively collect a pancreatic cancer cell. (The cell has a specific outside surface marker that the microrocket attaches to.) In the following three sections of the video, the microrocket is unable to collect the cancer cell, either because the rocket has not been modified, or because the cells do not express the right outside surface marker.
Video Caption (see below): In this 8-second video, a microrocket transports a pancreatic cancer cell in buffer solution and in human serum.
