Chinese scientists said they had developed robotic fish that could "eat" microplastics.
Researchers say the robots could be
C
1 in cleaning up plastic pollution in oceans.
The project was
D
2 by a team at Sichuan University in South-western China. The
researchers said the robots had already done well in shallow water and that they planned
to carry out more tests in
C
3 water.
The team said the robotic fish could be
A
4 by light. Turning on and off the near-infrared
light laser causes the fish's tail to move and stop. It can swim at a
C
5 of about
3.5 cm per second.
Wang Yuyan was a member of Sichuan University's research team. She told Reuters that
the small robotic fish were being used to
B
6 microplastics for research purposes now. But
Wang added that the team wouldn't stop improving the robotic fish
C
7 it could help clear
away microplastics from deep ocean areas.
"The robotic fish can take in different kinds of microplastics and even
B
8 itself when it
is broken," the researchers said. "And if a robotic fish is eaten by a real fish, the real fish can
A
9 digest the material. So it does no harm."
Wang said similar robots could be developed to be placed inside human bodies to take away
D
10
materials. And there is still much to be improved for the robots.
