Nanotechnology is changing all industrial sectors.
We see better, stronger electric cars that are not damaging our environment.
Renewable energy is available to more and more people every day.
We can now use solar energy at night.
We can store energy in batteries that last longer.
We are on a path to cure cancer with nanosensors – nanoscale devices that measure physical quantities and convert these to signals that can be detected and analyzed.
Nanotechnology is a growing research field that manipulates materials on a molecular scale.
For example, silver nanoparticles are added to clothing for their powerful ability to kill bacteria and fungi and prevent the nasty odors they cause.
As nanotech is tailoring materials, they are stronger, last longer, and are more durable.
Let’s see the three most AMAZING inventions everyone in the world should know about.
Nanosensors – the future of diagnostic medicine
A vital goal of diagnostic medicine is to diagnose medical problems as swiftly as possible, enabling clinicians to treat patients before any irreversible or long-lasting damage occurs.
This is where nanotechnology comes in.
Nanosensors are like “nano-needles” with a tip about one-thousandth the size of a human hair that pokes a living cell, causing it to quiver briefly.
Nanosensors are constructed from carbon nanotubes.
Once it is withdrawn from the cell, the nanosensor investigates the cell for any sign of irregularities.
Searching the cell for irregularities is possible due to the radiofrequency that is built into the sensor.
That frequency sends signals to an external computer, from which a clinician can access all of the information transmitted by the sensor.
Nanosensors sense whether cells attached to the implant are bone cells, bacteria, or inflammatory cells.
The last two cell types indicate infection or scar tissue formation that might cause problems for the patient.
That way, sensors can detect signs of early DNA damage that can lead to cancer.
The potential of this invention lies in the early diagnosis of potential problems inside the human body.
That means we can stop the disease before it comes.
Predicting cancer is one of the best uses of nanosensors.
Since cancer is a highly deadly disease early cancer treatment is the best solution for cancer patients since there’s still no cure for it.
With nanosensors, there is opportunity to provide early care.
Nanotechnology is saving lives.
DNA Nanobots – bugs that deliver drugs
At Israel’s Bar-Ilan University Institute of Nanotechnology and Advanced Materials, Ido Bachelet led a team of scientists that built tiny robots that can respond to chemical cues and operate inside a living animal.
More than that, they can operate as logic gates, essentially acting as real computers.
Nanosized entities made of DNA can produce the same kind of logical information as a silicon-based computer.
They are also called origami robots because they work by folding and unfolding strands of DNA.
They travel around the insect’s body and interact with each other, as well as the insect’s cells.
When they uncurl, they dispense drugs carried in their folds.
DNA Nanobots’ primary field of application is medicine.
“DNA nanobots could potentially carry out complex programs that could one day be used to diagnose or treat diseases with unprecedented sophistication,” says Daniel Levner, a bioengineer at the Wyss Institute at Harvard University.
This creation is OUTSTANDING; it changed the way our minds perceive bugs.
DNA nanobots that deliver drugs in living cockroaches are our new now.
Nanobubbles – water treatment
Considering global environmental challenges, such as depletion and water resources degradation, we can see a growing demand for water treatment.
Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use.
Nanobubble technology and its application for wastewater treatment have emerged as a problem-solving alternative for such challenges.
Nanobubbles are tiny bubbles with micrometers and diameters of nanometers with unique physical assets that make them useful for water treatments.
They have a large surface area as one of their remarkable properties. It enables them a mass transfer between gas and liquid phases, which helps to facilitate chemical reactions.
This way of water treatment has been applied in several sectors, such as plant industries and agriculture.
Nanobubbles have a diameter of 80nm. Bubbles this size don’t reach the surface.
Instead, they remain suspended underwater for months until they dissolve, moving randomly throughout the water.
This property of nanobubbles allows them to provide homogeneous distribution of oxygen throughout an entire body of water.
Except for many water treatment benefits, this invention allows both fresh-water fish and saltwater fish to live in the same water.
Although having various advantages, the usage of nanobubbles is still limited.
Many studies, researches, and testing must be done until we can use these inventions in all the ways we can.
Final thoughts
By creating new products, we are creating new possibilities for a better life on the planet.
Nanosensors are a great example of what nanotechnology represents – a way of living in the future.
The usage of cockroaches and experimenting with nanosensors is just the beginning of discovering innovations, thanks to nanotechnology.
Besides detecting cancer, we are going to cure cancer.
It is likely that someday we are going to stop the diseases from even occurring.
Pollution of water is coming to an end.
With new technology being developed and inventions such as nanobubbles getting better, we can see an end to many deaths caused by pollutant waters.
We have a chance to save many fishes and sea animals.
We will repair our ecosystem.
These predictions give us a glimpse of hope for a better tomorrow.
They make us feel safe and alive.
We are here to see more ideas, more innovations, more NANO.
Nanotechnology is making that happen.
We are ready for the NANOFUTURE, are you?
