Nanotechnology has evolved so fast that in less than two decades, scientists went from creating nanomaterials to producing nanobots, also known as nanomachines and nanites. To be more accurate, certain secretive government agencies had already created nanobots in the 1990s.

Due to the advancement in nanotechnology, scientists can now create nanobots to use for curing cancer and other “incurable” disease. However, in the wrong hands, these nanobots can be programmed to attack the systems of the body, including the brain.

What is nanotechnology?

Nanotechnology is the study and application of microscopic things at the nanoscale level. It often combines science, technology and engineering to create nanomaterials and nanomachines that are as small as cells. Some nanomachines can even be smaller than a virus. Nanotechnology can be used in many fields, such as biology, chemistry and physics. Furthermore, it can be used in medicine to cure disease and health conditions, including but not limited to cancer, diabetes and neurological disorders.

Nanotechnology in medicine


The use of nanotechnology in medicine opens the door to many great possibilities. Applying nanotechnology in medicine could revolutionize the way we use medicine to treat disease and tissue damage. For example, nanobots could be injected into the bloodstream to help cells fight harmful microorganisms and cancer cells when the immune system isn’t working properly.

Here is a list of some ways nanotechnology could be used in medicine:

Drug delivery: Using nanomachines to deliver drugs to specific locations in the body could be more effective than consuming pharmaceutical drugs or injecting drugs into the body. For example, nanobots could be loaded with certain DNA codes or drugs that are lethal to harmful microorganisms. When the nanobots are injected into the body, they can destroy harmful microorganisms by attaching themselves to them and injecting lethal doses of drugs into their body.

Detox: Nanites or nanobots could be used to absorb toxins and remove these toxins from organs and the bloodstream. A person who has a weak immune system and liver problems should benefit a lot from this type of nanomedicine.

Monitor health condition: Scientists have found that some nanomaterials have the ability to detect certain drugs and nutrients. With better understanding of nanotechnology, scientists could create nanomachines that have the ability to detect the levels of chemicals and nutrients in the body. This can be very useful for diagnosing disease and health conditions and finding ways to treat them.

Tissue repair: Nanomachines could be equipped with DNA or certain healing chemicals to heal damaged cells and tissues. As the cells and tissues are healed, it makes it easier for the body to recover from injuries.

Nanotechnology and cancer

Some universities are developing and testing nanosensors that have the ability to detect very low levels of cancer cells. These nanosensors are more sensitive than traditional cancer tests, making them great for detecting cancer at an early stage. Using nanosensors to detect cancer can reduce cancer deaths, because the sooner cancer is diagnosed, the easier it is to treat it.

Another method for treating cancer using nanotechnology is to equip nanobots with certain compounds, proteins and chemicals that are lethal to cancer cells. When these nanobots are injected into the bloodstream, they can seek and destroy cancer cells without harming healthy cells and tissues.

Researchers have also found that certain nanoparticles combined with gold nanoparticles are effective for starving cancer cells. These special nanoparticles are created to look like HDL cholesterol, so that when they attach to a lymphoma cell, they prevent cancer cells from attaching to real HLD cholesterol, causing cancer cells to starve to death. Another way to use gold nanoparticles to destroy cancer cells is to attach anti-cancer RNA molecules to gold nanoparticles and apply them to the skin or inject them into the body. As the nanoparticles penetrate the body of cancer cells, they can stop them from producing proteins and therefore preventing cancer cells from growing.

The dangers of nanotechnology

Nanotechnology has many great potential but in the wrong hands it could be weaponized to destroy the human body. In addition, relying too much on nanotechnology can weaken the body’s natural defense systems, making the body dependent on nanotechnology to survive.
