Scientists believe that the drugs could be administered by microscopic robots with changing configuration that you will swallow in the future.
The researchers created tiny gadgets that are about 5mm long and can navigate the narrow channels of the human body.
The tiny robots, developed by Swiss researchers, even change shape and speed when they travel in soft blood vessels and thick bodily fluids.
Engineers at ETH Zurich and the Swiss Federal Institute of Technology Lausanne (EPFL) have published some great images showing robots in action.
The robots, which have not yet been named, consist of a gel that reacts to heat and magnetic nanoparticles.
This allows them to be controlled by an electromagnetic field, the authors wrote in the journal Science Advances.
Based on the 'origami design principles', the researchers, led by Dr. Bradley Nelson, folded the gel into 3D shapes.
For the robots to move efficiently, the inspiration has been inspired by the bacteria, which move from place to place via a tail-shaped helix called flagellum.

This was imitated to create a "ream-like" extension from the nano-robot, to allow it to swim through the body.
Microorganisms also change shape to "navigate complex environments and occupy various ecological niches," the authors wrote.
"Nature has developed a multitude of micro-organisms that change shape as their environmental conditions change," said Dr. Nelson.
"This basic principle inspired our design of microbots."
When tested in a "blood-like" solution of sucrose, the robots "moved much faster than other prototypes," the authors wrote.
They also changed shape to sneak into glbad tubes with many bent pbadages, before returning to their original size. Robots must be very flexible if they have to cross narrow blood vessels and dense fluids at high speed.
"Our robots have a special composition and structure that allows them to adapt to the characteristics of the fluid in which they pbad," said Professor Selman Sakar, one of the researchers. agencies
