programmed

The researchers programmed the spheroids to transform into bone using microRNA technology.

Then, late in the evening, she realized she had programmed one of the machines analyzing the samples incorrectly.

Dubbed the NanoGripper, the nanorobotic hand also could be programmed to interact with other viruses or to recognize cell surface markers for targeted drug delivery, such as for cancer treatment.

"Phages can knock on every biological door, but they will only enter the ones they are programmed to find," says Carlos Filipe, a professor of chemical engineering and a senior authior on the paper.

"The e-Drive is programmed to act transiently and then disappear from the population."
