Scientists develop flexible robots that can swim through blood vessels to deliver drugs

Scientists have evolved small elastic robots which will tre form reckoning on ir surroundings and may swim through fluids. It could facilitate offer drugs to infected tissue someday in future. se super flexible biocompatible microrobots are me up of gel nacomposites to embrace magnetic naparticles allowing m to be mand, courtesy of an electromagnetic field.

se robots are capable of swimming through fluids and just ir form whenever needed. y also can pass via narrow blood vessels and tricky structures without compromising on velocity or maeuvrability, said group of scientists heed by Ecole Polytechnique Fédérale de Lausanne (EPFL)'s Selman Sakar and ETH Zurich's Brley Nelson.

study, posted in journal Science vances, defined smooth, bio-compatible device "like a living microorganism," twisting and turning with quick writhing movements in fluids that may be solid, tacky or moving at fast speeds.

"Nature has evolved a multitude of microorganisms that change shape as ir environmental conditions change. This basic principle inspired our microrobot design," Nelson said.

In dition to supplying more desirable effectiveness, those smaller soft robots can also be manufactured without problems at an affordable cost. For w, research team is running on improving overall performance for swimming through complicated fluids like those determined in body of human beings.

As per study, action process of deforming can be "programmed" ahe in time without sensors or actuators, letting robots morph into most suitable shape.

se robots may be eir mand, courtesy of an electromagnetic field or left to operate on ir very own into cavities by making use of fluid flow. Eir way, y will routinely morph into most efficient form, researchers described.
