Richard Feynman foresaw sixty years ago that nanoparticles and nanomachines may be extremely useful in medicine.
This aspect of his vision is also coming to fruition right now. Here are three examples of things that are already being done:
• Nano-Retina, an Israeli startup, has invented an artificial nano-retina that allows the blind to sight again. 4: it is made up of a small, flat implant with a high-resolution network of nano-electrodes. The nano-retina activates the optic nerve, causing incoming light particles to be collected by the electrodes and relayed to the brain as visual sensations.
• Nano biosensors detect antibodies and particular enzymes in human bodily fluids in a lab on a chip. On a credit card-sized chip, just one-thousandth of a millilitre of blood, urine, or saliva (or even less) is put. When it comes into touch with the desired substance, the nanoparticles embedded in it detect certain chemical, optical, or mechanical changes. As a result, the chip can identify a variety of medical signs in only a few minutes.
• Nanoparticles deliver medications directly to locations of inflammation or mutant cells, allowing for a more effective pharmacological assault. Because blood is as sticky as honey for such small particles, the topic of how to transport nanostructures in the blood has remained unanswered for a long time. Magnetic fields, for example, may now be used to direct them. Bioengineers want to utilize them in precision chemotherapies against cancer cells, among other things.
Nano-robots, often known as "nanobots," are extremely small nano-robots that hold great promise in medicine. Every two years, we'd go to the doctor for a health checkup, which would be replaced with a continuous nano-check.
- Nanobots would roam our bodies indefinitely, detecting viruses, gene changes, and harmful deposits in the circulation before they became a problem.
- They would then start treatment right away by administering medications straight to the illness location.
- They'd combat infections, reduce inflammation, remove cysts and cellular adhesions, unblock clogged arteries to avoid strokes, and even do surgery.
- They would submit the results immediately to the family doctor if required, who would then contact the patient to schedule an appointment.
- Many small nano-robots—biomarkers, labs-on-a-chip, and other telemedical devices—permanently circulate inside our bodies for health care and healing, according to doctors. Nanoparticles, also known as nanobots, might be employed in our food.
- They would assist us in digesting food in such a way that nutrients are absorbed as efficiently as possible by our bodies. This would be beneficial in the treatment of disorders that now necessitate a tight diet.
Researchers are also working on developing meals with nanoparticles on the surface that would mimic the flavor of chips, chocolates, or gummy bears while being nutritious and even healthful.
