Transcripts
human beings have a habit of building
big just a casual look through history
we'll show you that whenever humans have
developed we've preferred to go big the
pyramids of giza and mexico are a prime
example
then you've got the easter island
statues and stonehenge just to name a
few
but is bigger always better
in the last century scientists have
shown us that going small can also have
its benefits
look at the evolution of computers for
instance the first computer developed by
ibm the howard mark 1 was over 50 feet
long and weighed over 5 tons
today phones that fit in the palm of our
hand have greater computing power than
the first computer ever made
the reduction in the size of transistors
has allowed us to build smaller and
smaller computers and smart devices if
we look back just three decades ago
you'll probably remember that we used to
have big bulky telephones that we
couldn't take anywhere
the internet was a new concept and life
was very different three decades later
we've got smartphones 24 7 connectivity
and a completely changed lifestyle all
thanks to how successfully we've managed
to miniaturize technology
we're now at the cusp of yet another
revolution that will completely change
the way we live in the next two to three
decades
this change is going to be a mixture of
various ongoing revolutions such as the
fintech revolution ai development and
nanotechnology which is the topic we'll
be covering in this video
the term nano was first introduced by
norio tanaguchi in 1972 to describe the
science of assembling atoms into new
forms but back then it wasn't that
widely known or understood
nanotechnology is the science of
engineering material fabrication and
micro scale patterning at the molecular
and atomic levels
this nanotechnology involves the
manipulation of matter at a scale
smaller than 100 nanometers a nanometer
is 1 billionth of a meter which is 10
times the diameter of a hydrogen atom
to put this in perspective the diameter
of a human hair is on average 80 000
nanometers
making new things at such a small scale
is called nanotechnology
at such scales the ordinary rules of
physics and chemistry no longer apply
to prevent this video from getting too
complex it'll be easier to understand
nanotechnology through the example of
ant-man
if you've seen the avengers you'll know
that every time ant-man shrunk himself
time became relative to him
ant-man in his shrunken form appeared to
move faster than his normal-sized
friends and enemies similarly when he
became bigger during the fight scene in
civil war
time kind of slowed down for him
his normal movements took too long which
allowed spider-man and iron man to bring
him down easily
this is the same effect that makes it
almost impossible to catch a fly
from the perspective of a fly we
literally move in slow motion
now if you keep going smaller from human
size to ant size and from ant size to
the size of a molecule and even further
from molecular size to subatomic size
at each new level a new dimension will
open where the laws of physics will not
be the same to you as they were on the
basic human size level
this is called the quantum realm in the
simplest of terms
nanotechnology therefore allows us to
explore uncharted territory
the possibilities are endless because
we're just beginning to understand what
we can accomplish with this technology
think of it like this
the basic unit of matter is the atom
everything that we see and feel around
us is made of atoms you're made of atoms
the phone that you have in your hand the
couch you're maybe sitting on or the car
that you drive everything is made of
atoms even the air we breathe and the
water we drink is made of atoms
so the question is if everything's made
of atoms
why do we then have different forms
shapes objects and colors
well it turns out that the way in which
atoms are arranged determines how
anything appears and functions
this is similar to a lego
you can use lego blocks to build
anything
the same lego block can be used to make
a car or a building
similarly atoms can be used to make
anything but once they join together to
form a certain shape they then take the
physical and chemical properties of that
object
let's look at another example to make
this even more interesting
the human body has numerous elements in
it our blood has iron which is very
important for strength
we have zinc in our bodies which is
needed for the immune system we even
have traces of gold silver and copper in
our blood
all of these minerals and elements are
needed for the body to function properly
but the question is where did this iron
come from
irons not naturally found on earth
every last bit of iron present on earth
once came from the core of a star
and stars only make iron when they're
about to die out
similarly there's no way to make gold
naturally
gold in the entire universe is only
created when two neutron stars or a
neutron star and a black hole collide
and merge
this explosion is called a kilonova and
it's the only place in the universe
where gold and heavier elements can be
created
the gold in our bloodstream was once a
part of some kilonova billions of years
ago
so the same atom that was once inside a
dying star is now inside our bodies
giving us life and strength
this whole explanation shows us that
atoms can be rearranged to take
different forms and fulfill different
functions
the ability to manipulate atoms in this
manner is what we call nanotechnology
the term nanotechnology gained traction
around the late 80s with the publication
of eric drexler's book the coming era of
nanotechnology
in this book eric drexler discussed
nanotechnology at length and proposed a
nano scale assembler
a type of device that can use available
raw material to build a replica of
anything
to understand this concept think of a 3d
printer that can print anything if you
have the right raw materials
the idea is quite common in games like
prey where you can recycle objects break
them down into atoms and then fabricate
anything you want from the available
atoms the process of fabrication is not
fictional it's an actual process that's
being used to create nanotechnology that
is already a part of our daily lives
nanotechnology has far-reaching
applications in various fields including
the food health energy agriculture
electronics and environment
it's also used for medicinal purposes
the human body is full of nano-sized
structures such as proteins dna and
cells
nanotechnology offers promising results
to improve their function and stability
biomedicine is an important area for
nanotechnology research
nanotechnology can be used to create
more effective medical treatments and
medicines that target the affected area
to increase the rate of healing and
reduce the negative side effects and
treatment
several anti-cancer drugs including
heckle taxal
bison
5-fluorocell and dexamethasone have been
successfully formulated using
nanomaterials
these drugs have been used for cancer
treatment for over a decade now
more recently nanotechnology came into
the limelight when a team of researchers
won the nobel prize for crispr
which is a nanotechnology-based
gene editing methodology that allows
scientists to cut and paste our genes
for more effective treatment this is the
same technology that's being used in
vaccines to fight against the deadly
pandemic
nanotechnology is also being used to
develop cost-effective ways to generate
sustainable energy
kyoto university has developed a
semiconductor through nanotechnology
that can absorb twice the amount of
sunlight to create more energy than
conventional solar panels
similarly nanotechnology is being used
to create lighter and cheaper materials
for wind turbines
this is one key reason why the cost of
creating sustainable energy is
continuously coming down
nanotechnology is also being used in
fabrics to create next generation
waterproof clothing
shoulder technologies is using a
treatment called nanosphere to coat
fabrics with nanoparticles making them
not only waterproof but also dirt and
dust proof
now that's a breakthrough i can get on
board with
another great example of nanotechnology
being used in our lives is the food
industry
genetically modified seeds produce more
and better quality crops with increased
nutrients
genetically modified crops also don't
need pesticides so they end up reducing
the cost of food to start with
nanotechnology is also being used in the
meat industry to mark meat with
fluorescent nanoparticles that can
indicate the presence of certain
pathogens and bacterias
while nanotechnology has seemingly
endless possibilities it also has a few
drawbacks and disadvantages that need to
be carefully assessed
for instance on one hand genetically
modified seeds have the solution to end
global hunger and malnutrition but on
the other hand there are also adverse
health effects of some genetically
modified food crops
companies that excel in gmo food crops
have been sued for potentially harmful
effects on humans
crispr is another prime example of how
unrelated nanotechnology can cause
potential harm
he jankui the chinese researcher
conducted gene editing tests on human
subjects without prior approval he used
gene editing on two twins with
hiv-positive parents in an attempt to
create children immune to the virus
jonqui's attempt landed him in prison
stripping him of his titles and
privileges
eventually the benefits of
nanotechnology will push it towards
increased acceptance in every field of
life
nanotechnology is already around us but
now it's going to morph into something
that we've only seen in fiction
imagine the possibilities if
nanotechnology can be combined with
robots and ai
yes we're talking about smart nanobots
which are still in their early
developmental stage but this is the
future guys
not just nanotechnology but smart
nanobots
and that's a wrap
