What is nanotechnology?
Nanotechnology is the study of extremely small things or particles that can be used in every field or aspect of life. Today nanotechnology is used in chemistry, biology, physics, material science, engineering etc.
Nanotechnology in medicine
Nanoparticles have been a subject of interest to scientists for centuries. The roadblocks faced are mainly due to the inability to see the structure of these nanoparticles. With the development of strong microscopes that are capable of seeing particles as small as atoms, it has become really easy for scientists to see what they are working with.
Advantages of nanotechnology in medicine
With the development of nanotechnology, nanoparticles can be used in a lot of areas.
1. Nanotechnology in medicine can be used to provide better chemotherapy treatments. Nanoparticles can be used as drug delivery agents to cancer cells in patients undergoing chemotherapy.
Chemotherapy today is done to a mass of cells affected by cancer, which are likely to kill healthy cells as well. Nanoparticles will be able to attach themselves to the cancer cells and release the drugs directly into the affected cells, thereby reducing discomfort to the patient and resulting in quicker treatments.
2. With nanoparticles added to conventional materials, garments can be made water and stain-resistant.
3. When conventional materials form nanoparticles, their properties tend to change since nanoparticles have greater surface area per weight as compared to larger particles. It has been found that the nanoparticles in iron can clean up chemicals in groundwater as they react better as nanoparticles than larger iron particles.
4. Nanoparticles of carbon have been found to be very strong and can be used to make bullet-proof vests.
5. Scientists have been working on developing a method called molecular manufacturing, where a device called molecular fabricator will be able to manipulate the position of atoms and molecules to build any inanimate object.
With the developments using nanoparticles, the future may already be here! Nanotechnology in medicine will open doors to immortality. Scientists predict that immortality could be a reality in the coming 40-50 years. We could have nanobots or microscopic machines traveling through our body repairing damages as they occur.
Not just the physical aspect, but nanotechnology will also enable memories and personalities to be backed up. Human beings will live in collaboration with machines as nanobots move through the bloodstreams and may develop the potential to replace biological blood!

Death by means of accidents will still occur, but the physical damage caused by diseases can effectively be cured or reversed. With nanobots in the bloodstream, wounds will heal instantly and limbs can be re-grown. Loss of memory from head trauma can be rectified using the backed up memories.
However, with technology so great, there will be dangers too. With intelligent technology flowing through our body, we fall at the mercy of these bots running effectively. Malfunctions can turn deadly. Immortality will come at a cost and as always, caution needs to be exercised in dealing with it.
