Scientists invent live cells and blood nanotubes to track new technology

Researchers at Purdue University in the United States have invented a new imaging technology that tracks carbon nanotubes in living cells and blood, making nanotubes ideal for biomedical research and clinical medicine. Related research papers were published online on December 4th in the journal Nature-Nanotechnology.

There are currently two types of nanotubes that have potential applications in drug delivery and cancer research imaging; however, no single technique has ever been observed in living cells and blood. The technology invented this time is called “Transient Absorption Imaging System”. Pulsed near-infrared laser is used to send energy into the nanotubes, and then it is detected by the second laser. This technology does not require dyes to label nanotubes, making it potentially useful in scientific research and pharmaceutical applications. In addition, scientists have eliminated the background interference of red blood cells by passing signals from different "channels" through red blood cells and nanotubes.

The research leader and Chinese scientist Ji-Xin Cheng said that the technology can observe the circulation of nanotubes in the blood in real time, and can provide researchers with relevant information to understand how to apply nanotubes perfectly in research and clinical application.
