Microbots in Your Blood Could Help Destroy Cancer
6th February 2022
Scientists recently printed teeny tiny microbots in the shape of different animals, like fish, crabs, and even butterflies. But the coolest thing with these bots is that they don’t stay in one shape — they can morph into different shapes because they are 4D-printed.
4D printing works the same as 3D printing, the only difference is that the printing material allows the object to change shape based on environmental factors.
In this case, the bots’ hydrogel material allows them to morph into different shapes when they encounter a change in pH levels — and cancer cells, as it happens, are usually more acidic than normal cells.
