Over the years, the medical industry has created some of the most capable medicines. Yet, they keep searching for potential new drugs to help people in need. It is where nanomedicine comes in. Nanomedicine is a branch of science that uses nanotechnology with drugs or diagnostic molecules. The main motive behind this is to increase the ability of cells and tissues.
In addition to this, these nanoparticles are safer to be introduced into the body. Various applications of nanotechnology in medicine are imaging, diagnosis, and the creation of effective drugs to treat diseases. This article will highlight some of the applications of nanotechnology that have the potential to change medicine.
Micro-Medicine with the Potential to Changing the Medicine Industry:
Before learning about the applications of nanotechnology in medicine, first, learn about what is nanotechnology.
What is Nanotechnology?
The word ‘nano’ originated from the ancient Greek word ‘dwarf.’ In science, nano means one billionth (10 to the minus 9) of something. For example, a nanometer would be one billionth of a meter or 0.000000001 meters. Fun fact, a nanometer is 40,000 times smaller than the thickness of a human hair and is only three to five atoms wide.
A typical virus is only 100 nm in size. Thus, the ability to manipulate medicine at the nano level is pretty powerful. It is like having a laboratory at the sub-atomic level and manipulating cells with your hands.
Applications of Nanotechnology in Medicine:
Manipulating DNA to cure some diseases is seriously being considered by many medical professionals. Many are seeking therapies that have the potential to manipulate an individual’s genes or molecular pathways as options to cure diseases. But the primary reason for choosing this is because of its ability to create treatments according to the genetic markup of a patient.
Thus, it also creates the need for new tools that can help scientists in their experiments to develop new medicine. Imagine this, being able to stretch out a section of DNA like a strand of ramen and study it. You can examine it and even put nanobots to repair the cells from the inside. This will surely prove beneficial to the medical industry and patients too.
Nanostars or Nanobots:
The chemists at New York University (NYU) have created a nanoscale robot using DNA fragments that can walk on two legs and is only 10 nm in size. Nano Letters, a paper published in 2004, reveals that it can walk using psoralen molecules attached to its feet.
Furthermore, to target cancer cells, DNA-based nanobots are also being made. The thought behind this is that it can transport a molecular payload containing specific instructions to a definite cell. It will allow the cell to behave in a certain way that is inscribed in the molecular payload. The researchers at Harward Medical School reported that using this technology, they were able to trigger cell suicide in leukemia cells.
Measured in less than 1,000 nm in diameter, nanofibers have the potential to create special materials that can aid patients and medical professionals. These special materials include wound dressing, surgical textiles, materials for implants, tissue engineering, and artificial organ components.
Carbon nanofibers have great promise for medical imaging and precise scientific measurement tools. But there is a catch, these nanobots are hard to create, and maintaining consistency in size is another problem. Moreover, it is time-consuming and costly.
What does the Future Hold for Nanotechnology?
Recently, the research surrounding nanotechnology in medicine is mushrooming. Variety of studies exploring medical applications of nanomaterials and nanomaterials have come to light. This also simultaneously increases the concerns related to nanotechnology. The greatest concern is how to scale up the production of nanomaterials and tools. Other concerns include high costs and timescales.
But the public still has safety concerns related to nanotechnology. It is something that needs more attention. If these concerns are resolved, nanotechnology has a bright future ahead. These concerns are simply exaggerated against the greatness of nanotechnology.
Nanotechnology has great potential in the medical industry. Moreover, it can help to fight against diseases that are hard to treat. With more research, scientists can find all the concerns related to safety and resolve them. Tell us what you think of nanotechnology in medicine. Thank You!!!
