shark skin and bio fouling. What does it mean?
00:04 - 00:06
And what can it do for the field of science?
00:08 - 00:12
Bio fouling is the scientific term for the build up of moss, barnacles,
00:12 - 00:16
urchins and other forms of bacteria onto marine animals and structures.
00:16 - 00:19
Well, it's not generally harmful for animals.
00:19 - 00:23
It can have severe negative effects on system performance in structures.
00:27 - 00:29
So what does bio fouling have to do with sharks?
00:29 - 00:30
Out of curiosity,
00:30 - 00:34
scientists decided to conduct various experiments on sharks to see if they
00:34 - 00:38
could figure out why bio fouling occurs with whales and dolphins,
00:38 - 00:39
but not with sharks.
00:39 - 00:43
They discovered that sharkskin itself was not an antimicrobial surface,
00:43 - 00:48
but rather it is just highly adapted to resist the attachments of living organisms.
00:52 - 00:55
So how could this affect science and medicine in the future?
00:56 - 01:00
A corporation called Shark lit Technologies specifies in research
01:00 - 01:03
and replication of sharkskin for scientific purposes.
01:04 - 01:07
The corporation was founded by Anthony Brennan.
01:07 - 01:09
In one of their most promising experiments,
01:09 - 01:11
they went to a hospital and covered multiple
01:11 - 01:13
surfaces with the shark skin light coating.
01:14 - 01:18
They then spread bacteria onto the coated surfaces to mimic coughing and sneezing.
01:19 - 01:22
They discovered that the surface is covered by fake sharkskin
01:22 - 01:23
prevented bacterial
01:23 - 01:26
bacterial transmission by 97%
