DNA Data Storage and Miniature Lens

DNA Data Storage and Miniature Lens.


Day by day, new technology is making our lives easier. With the advancement of science, new technologies added to our lives. But not all of them have the same effect. Some will be lost within a few days, the face will mute like most technologies, but some will survive for long. The World Economic Forum listed some of the top technologies on Scientific American Magazine. DNA data storage and Miniature lens is the hot cake of the previous year.


DNA data storage

DNA (Deoxyribonucleic acid) is known as the particle of any living being. Who knew it could be a data storage? But this happened. This life information holder DNA now used as a vast database. Moreover, this is practical now.

According to software company Domo, In 2018, Google conducts 3.38 million searches every minute, and 4.33 million YouTube views. It is estimated that one person will create 1.7 MB data per second worldwide this year. This will generate 418 billion terabytes of data or one zettabyte (1 trillion gigabytes) of data in just one year. Optical or magnetic data storage systems are currently in use. These binary storage systems will usually not be able to store this information for more than a hundred years. It also requires a lot of energy to run a data center.

Simply put, as time goes by, this problem will become apparent. The alternative to this hard drive may be a DNA-based database. It consists of long chains of nucleotides (adenine, guanine, cytosine, and thymine). This will mark the beginning of a brand new information technology journey.

DNA data is incredibly stable. And it doesn't require too much energy to contain information. The most significant advantage is that DNA can store much more information than electronic devices. Only one cubic DNA of the bacterium Escherichia coli can fill with one year's worth of information in the current world. Using DNA as data storage is no longer just theoretical. Its application has already begun. It has found that about ninety percent (90%) of the E.coli worked correctly. However, there are some challenges when it comes to using a DNA storage system. Cost and speed are some of them. The rate will not in control of us; on the other hand, make DNA as the database can be highly cost. So competition with electronic storage has to gain a lot of momentum. The DNA storage system may not be used everywhere. However, it is sure that this DNA storage will be handy for long-term data retention.


Miniature lens

Small and flattened meta-lens can be an alternative to large glass lenses. Computers, cell phones, or other electronic devices are becoming shorter. However, their optical instruments not shortened. It is difficult to make small lenses in the manner of cutting or engraving the traditional glass. However, scientists have recently been able to produce a small number of meta-lens. However, if we use this technology, it will be possible to reduce the laboratory equipment, including the microscope significantly. Not only that, but there will also be considerable changes in the form of consumer products such as cameras or virtual reality headsets. It will also increase the efficiency of optical fibers. Meta-lens are even thinner than microns. One micron equals one-tenth of a millionth of a meter.

Interestingly, the meta-lens are so thin that they do not change significantly in size, even when arranged one after the other. It will also serve as a solution to the spectrum problem. It can prevent the image from becoming blurred. Meta-lens will ultimately reduce costs significantly because they can be made from the semiconductor equipment. But the nanoscale instruments are not cheap, it is costly to fit on a centimeter scale chip. They also do not contain such subtle color images as traditional lenses. They are not yet suitable for high-quality photographs. However, in the next few years, meta-lens will probably play a more active role. Maybe this technology will widely use to determine various diseases, such as endoscopy equipment. Already, it has attracted the attention of companies and multiple laboratories such as Samsung and Google.
