How Nanotechnology Could Change the World

 

Nanotechnology is one of the most exciting and promising technologies available today. It drives innovation in a variety of sectors and allows industrial designers to create entirely new properties through the controlled manufacture and structuring of materials.Of late, the technology has been applied in many sectors, and it has opened the doors of implementation in many other areas where it will play a significant role in shaping the future and growth of the world.As scientists continue to experiment the many new ways nanotech will bring about a positive outcome, we look at some of the applications that will have the most impact in the world.

What is Nanotechnology?

Despite the hype surrounding it and its perceived potential for many diverse fields of science, nanotechnology can be difficult to comprehend. This is not surprising considering it’s a wide field. Nanotechnology refers to a technology that involves working with materials at the scale of one billionth of a meter. In other words, it relates to a technology that is between 1 to 100 nanometers in size. The prefix “nano” refers to one billionth. Nanotechnology scientists use atoms and molecules to make amazing new technologies that help improve electronics and nearly all aspects of modern life.

Benefits and Applications

Nanotechnology has several advantages and applications across a range of industries:

  1. Treating spinal cord injuries

Nanotechnology has shown significant potential in the treatment of spinal cord injuries. Scientists at the Institute of BioNanotechnology in Medicine at Northwestern University have shown that nanotechnology can be used to stimulate the body to heal itself by injecting “molecules that were designed to self-assemble into nanostructures in the spinal tissue.” When injected into the bloodstream with a syringe, these molecules repair damaged neurons, preventing the damage caused by inflammation and scarring.

  1. Heal injuries and restore organ function

In addition to being a breakthrough in the treatment of spinal cord injuries, nanotechnology offers exciting results when it comes to repairing injuries and restoring aging tissues. Scientists at The Ohio State University developed a new technique, called tissue nanotransfection, which helps to turn skin cells into other types of functional cells that can then be used to repair or restore function to damaged tissues such as nerves, blood vessels, and organs, among others.

The procedure uses a tiny device that is placed on the surface of the skin to replace injured or compromised organs by incorporating some new genes into them. Using the technology, the researchers successfully fixed mice that had lost blood flow to their legs within 14 days. Plans are underway to start clinical trials in humans as soon as possible.

  1. Generating electricity from motion

Researchers at Vanderbilt University developed an ultrathin device that produces electrical current from human movement. The device, which is made up of layers of very thin black phosphorus and is powered by battery technology, harvests energy when it is pressed or bent during human motion.

When the black phosphorous nanosheets are bent or pressed, this action produces an electrical current that is then tapped and stored in the battery. This has been made possible by the thin size of the sheets, which makes it easier to incorporate them into clothing as well as the ability of the nanosheets to harvest energy at low frequencies. The nanosheets can generate electric current at movement speeds as low as 0.01 Hz.

This means that energy can be harvested from one movement cycle every 100 seconds from everyday activities such as walking, sitting, and standing. The Future is in Nanotechnology Globally.

How Technology is Changing Security Procedures

 

 

In an age where technology is beginning to take over the world, security is becoming a huge factor. Security procedures are needing to adapt in order to ensure that people are continually protected at all times, whether that’s at the airport, online or visiting the hospital, and there are a number of new technologies that are being implemented in order to adapt and change security procedures. Here, we’re taking a look at how technology is changing security in a number of different sectors around the world.

Online Security

One of the biggest concerns that people have when it comes to going online is whether or not their personal details are able to be stolen. When it comes to filling out personal, financial details on sites like Wizzcash.com or other financial institutions, there is a lot of personal information that could be taken by hackers. However, new technologies like cloud-based systems and biometric scanners can help to ensure that a person’s identity is protected and personal data cannot be stolen without legitimate identification processes. While this is not in practice yet, with huge hacks around the world like the NHS ransomware attack, it is highly likely that stronger security measures will be put in place to protect data in mind.

Airport 3D Scanning Systems

In the US, a company called Analogic uses a 3D scanning system suited to scanning hold luggage, based on the idea of a CT scan. The concept behind this technology is to stop people from having to take out things like liquids and laptops from their hand luggage as it is able to be put through the scanner with any threats indicated quickly and officially. These scanning systems could one day also be rolled out on a larger scale, meaning countries all over the world won’t have to see toiletries being stuffed into plastic bags and left out to put on the trays separately.

Biometric Iris Scanners

The E-passport gates in some UK airports not only allow queues to be reduced in the airport when trying to get through passport control, but they also help to heighten security levels without the added hassle and stress. The rise in biometric iris scanners in airports mean that people who may swap their passport with someone they look similar to will get caught instantly, and the gates won’t open. Facial recognition technology is also slowly coming into play, meaning the airport is able to understand and monitor the profile of every traveler trying to go through the gates, further increasing security measures.

Patient Identification

One of the biggest issues behind patient identification is the lack of privacy and easily accessible documentation. Data isn’t quite as secure in healthcare as many people tend to think, but a number of new technologies are beginning to be introduced in order to reverse this. Biometric patient identification processes are just one example of how these types of processes can be improved, to ensure that data and patient identification documents remain as secure as possible. This will include strengthened security and compliance, locking medical records to ensure there are no mix-ups and also accurately identifying patients to prevent fraud and human error.
