Scientists invent new drug treatments: nano rockets

Release date: 2016-12-16

Nano rocket (nanorockets) is a drug delivery body in the best mode. According to "Natural Chemistry" magazine, researchers at the University of Fort Lauderdale in the Netherlands have successfully developed a nano-rocket that can be adjusted according to the temperature of the diseased body tissue. Interestingly, in practical applications, the temperature sensitivity causes the rocket to stop in the diseased tissue because the temperature of the affected area is relatively high.

 

The soft nano-rocket system that the researchers plan to develop has the ability to self-assemble and can be made up of anything like a drug-containing pill. Research director Daniela WIlson said, “ The biggest challenge we face is to combine them with a multi-functional product. Now we have the system with a molecular-level brake system that allows them to start at a specific location and Stop. "

 

It is understood that this brake and advance function is to use the nano-rocket system to utilize the long-chain reaction of the polymer on the surface of the nano-rocket. These polymers can expand and contract according to the ambient temperature, which is equivalent to the rocket's fuel switch, allowing the rocket to advance and the hind legs. Researchers say their sensitivity is high, and when the temperature exceeds 35 °C, they shrink immediately and the rocket stops moving forward. But it will not affect the catalytic response of the nano rocket and the shape of the rocket. Even if the equipment is fueled less, it can reach the lesion directly.

 

The "turning" function of the nano-rocket is to use its core low-frequency magnetic field, which can be attracted by the magnetic strip to reach any predetermined position.

 

Of course, the researchers said that this is only the product of their experimental phase, and there is still much room for improvement. Although nano-scale rockets will not be toxic to human cells, they cannot be completely degraded in the human body.
