Researchers of University of Exeter created small magnetic robots with head and tail of few millimeters in size . They 'swim' to a desired location when activated under a magnetic field.
According to Researchers the devices could be used to deliver drugs to desired areas of the body resulting in dramatic increase of treatment time and success.
As per Researchers these devices could revolutionise the wider field of microfluidics, which focuses on moving liquids in extremely narrow channels.
Researchers further said that these Robo-sperm like devices could provide a cheap, efficient template for drug-delivery systems in human subjects .
Exeter researchers created several swimmer prototypes with tails ranging from 1 to 12 millimeters long.
The team kept these swimmers loose in fluids of different viscosities and applied electromagnetic currents of varying intensities .
The researchers found that swimmers with 4 mm long tails moved faster and are best controlled.
According to scientists of Exeter university This is the first robotic swimmer that could be produced on industrial scale, thus creating a way for making disposable and cheap microfluidic chips.
The researchers are currently working to create swim robots of much more smaller in size.
According to "The Oxford Companion to The Body," there are many human capillaries with a width of 8 micrometers — about 500 times smaller than the current swimming sperm robots and 3,000 times smaller than the aorta .
Current swim robotic sperm has capability to swim through a blood vessel with a diameter of about 25mm
This type of advanced technologies is going to revolutionise the field of microfluidics providing a efficient and simple way of manipulating liquids at a microlevel.
