Scientists have developed a new method to transport anticancer drugs by nanoparticles

Recently, researchers have developed a new method to deliver a class of anticancer drugs (http:// to cells more completely and accurately using nanoparticles, so as to achieve better anticancer effect, according to a study released by the University of Cambridge A class of anticancer drugs called small interfering RNA (siRNA) can play a very good role in inhibiting the over expression of carcinogenic genes, but there are still some problems to be solved for this kind of drugs, such as it is difficult to enter the cell, and it needs to use a suitable delivery medium The research team published a paper in the latest issue of the American Journal of chemistry, saying that through computer simulation technology, they found that a kind of nano particle called "metal organic framework" could be competent for this role Due to the difference of structure and material, there are thousands of different types of metal organic framework, which has strong plasticity The team moulded it into a carrier of the right size, which can deliver siRNA drug molecules, and the nanoparticles will degrade themselves when they enter the cell, thus releasing drug molecules to the target David Fallon Simmons, Ph.D of Cambridge University, the corresponding author of the paper, said that for traditional cancer drugs, considering the size and shape of drugs in the design process, it is necessary to develop suitable "metal organic framework" carriers for each drug As for siRNA, once an effective "metal organic framework" has been developed for it, it can be used to deliver a series of different siRNA drugs and treat many diseases in principle
