Mankind’s continual advancement in technology has led to numerous discoveries. With this continuity of innovation and development, doctors are now implementing the use of nanotechnology in the medical field. Nanoscience is a field of study that involves using and manipulating molecular and atomic particles. Recent developments in this sphere of learning and technology have been revolutionary for all fields related to biology.
Modern Science and its connection to Nanotechnology
What sets this apart from all other discoveries is the distinct and idiosyncratic functionality that the technology has to offer. Its microscopic size allows for newer possibilities and curing techniques to emerge. That doctors of all fields can utilize. This has led to the formation of a new branch of medicine called ‘Nanomedicine’. It works on the fundamentals of nanotechnology. This field of science uses both organic and inorganic substances for multipurpose treatments. Such as the delivery of drugs, repairing cell tissues, and even eliminating foreign or harmful particles inside the human body.
Applications of Nanotechnology
It is no doubt that Nanoscience brings new treatments and cures for the medical field. Among the number of applications this technology has, the most recognized utility is the ability to use it as a detector device that can detect even cancer cells inside the body. Due to its microscopic size, its easily introduced inside the body and can help with detected damage or diseases before their symptoms even occur.
Another great application is drug delivery to only specific cells and tissues that are decaying or infected. Due to the nature of the technology, this helps separate the drug from the healthy cells making sure no harm reaches them. Research is being conducted to use infra-red or heat properties to subdue bacteria or cancer cells without harming other parts of the body in the process.
Polymers can also function as a substitute for synthetic platelets that combine with nanotechnology to stop internal bleedings and aid in the recovery and regeneration of damaged cells and tissues. This regenerative aspect of the technology can also be beneficiary for cell therapy-related treatments. They can transmit cells into a body to accelerate their healing factor.
The Age of Nanobots
The brilliance and multi-variant use of this technology has introduced the use of nanorobots or Nanobots for short. These bots are being utilized as a dental accessory to enhance or rectify the enamel layers of teeth. Nanorobots are capable of destroying and eliminating the formation of plaque in the sensitive areas of the mouth where traditional dentistry methods fail to comply.
We no longer have to cut open a body for surgery. Nanobots being guided by a surgeon are capable of performing surgeries inside the body without any complications or use of force as they can operate without disturbing other organs inside the body.
Self-powered implants are using this technology in sensors, portable electronics, and other medical devices to help patients carry about their daily lives without much hassle.
Scope of Nanotechnology in Pakistan and other countries
As of now, the developed countries are more laser-focused about the use of nanotechnology in the field of medicine. They are continually investing and streaming resources to better understand the extent of this technology and its benefits.
Japan and United States are the leading front runners who have started the largest research programs on Nanotech. Over $42 billion have already been invested in this field.
From the majority of Islamic Countries, only six stand out with having shown any interest in the development of nanotechnology. Among them is, Turkey, Iran, Egypt, Saudia Arabia, Malaysia and Pakistan. Sadly, Pakistan does not have a national-level program that focuses on the development of this technology. However, we hope that the government will soon realize the importance and benefits of Nanotechnology. In doing so, they will give the health care system of this country a chance to thrive once again.
What to expect of the future?
There is still plenty of research and development that goes to enhance and improve medical practices aided by the use of Nanotechnology. Hopefully, along with the advancement of this technology, doctors and scientist will adhere to the safety regulations to make sure that this technology serves as a means of cure and recovery instead of disaster and calamity.
