This incredible nanoinjector was created at Brigham Young University, is capable of penetrating a cell wall and delivering DNA.
The clever device does this by drawing negatively charged DNA to its positively charged lance. It then penetrates a cell and reverses polarity, injecting the DNA in the process.
The uses in nanomedicine could be huge, especially in areas such as treating cancer, Alzheimer’s disease, and diabetes, where gene therapy could lead to more effective treatments. The injector also can be used to more easily deliver human diseases to lab animals like mice, who can be used in the search for a cure.
Another bonus: The injector doesn’t work like a syringe, which tries to pump DNA-filled liquid into a cell but kills the cell about 40 percent of the time. This method makes the tiniest of incisions and simply drops off the DNA before exiting the cell, giving the cell more of a chance to replicate and prosper. Watch:
