Nanomedicine uses nano-sized tools for the diagnosis, prevention, and treatment of disease and to gain an increased understanding of the complex underlying pathophysiology of the disease. The ultimate goal is to improve the quality of life. The aim of nanomedicine may be broadly defined as the comprehensive monitoring, repairing, and improvement of all human biological systems, working from the molecular level using engineered devices and nanostructures to achieve medical benefit. Most broadly, nanomedicine is the process of diagnosing, treating, and preventing disease and traumatic injury, relieving pain, and preserving and improving human health, using molecular tools and molecular knowledge of the human body.
Nanomedicine makes use of tiny instruments to better understand the intricate pathophysiology of disease and to diagnose, prevent, and treat illness. The ultimate objective is to raise people’s standards of living. The goal of nanomedicine can be summed up as the thorough monitoring, maintenance, and improvement of all human biological systems while operating at the molecular level and utilizing designed tools and nanostructures for therapeutic purposes. In its broadest sense, nanomedicine refers to the use of molecular instruments and molecular knowledge of the human body in the diagnosis, treatment, and prevention of disease and traumatic injury, the alleviation of pain, and the preservation and improvement of human health.
A new area termed nanomedicine has emerged as a result of a growing interest in the medical uses of nanotechnology. 3,4 They might eliminate cancerous cells, clear blockages from the circulatory system, or take over the role of subcellular organelles. In the same way that an artificial heart has been created today, an artificial mitochondrion may be created in the future. 2 For the treatment of human diseases and the improvement of human biological systems, nanomedicine holds the promise of strong new instruments. 3 The capabilities of diamondoid-based medical nanorobotics may be significantly enhanced compared to those of natural biological systems, even surpassing those made feasible by tissue engineering and biotechnology. This examination will look at some of the worst medical conditions and how nanotechnology could be able to treat them.

Diseases and Nanomedicine Treatments
Impressive advancements in medical science have been made. Bacterial illnesses have dramatically decreased because of antibiotics. Diseases caused by vitamin and mineral deficiencies are now uncommon in affluent countries. However, there are still a lot of illnesses that shorten our lives, and the relevant medications can only delay them rather than cure them. Without healing every illness that poses a threat to shortening life, it is impossible to extend it indefinitely.
chemotherapy for cancer
Cancerous tissues typically differ significantly from normal tissues at the cellular level. Since many cancer cells alter the substances on their surface, they are simple to spot. Though every cancer involves a genetic alteration that alters the molecules within the cell, most cancer cells grow more quickly or change shape. The immune system uses surface markers to attack cancer cells, but this is insufficient to prevent us from developing the disease. Nanobots will have several benefits. They can first physically access cells and scan the chemicals there. Second, they may have internal computers that enable them to perform calculations immune cells cannot.
Thirdly, unlike the immune system, which is always speculating if cancer exists, nanobots can be programmed and put to use after a tumor has been identified. If cancer is found, nanobots can immediately eradicate it using more targeted and forceful methods than the immune system are intended for. They can scan every cell in the body for signs of cancer and carefully examine any worrisome cells. With such molecular tools, a compact device for locating and eliminating cancer cells can be created. The apparatus would have a small computer, several binding sites to measure the number of particular molecules, and a supply of some poison that could be released selectively and be capable of killing a malignant cell. The mechanism would move freely.
. The device would move freely around the body and take periodic environmental samples by checking to see if the binding sites were occupied. Statistics on occupancy would make it possible to calculate concentration. Monoclonal antibodies of today can only attach to a particular kind of protein or another antigen, and they are not effective against the majority of malignancies. The cancer-fighting tool described here may include a dozen separate binding sites and hence could track the amounts of a dozen various molecular kinds. The computer could check to see if the concentration profile matched a pre-programmed “cancerous” profile and would discharge the poison if it did. Brain Injury Prevention in Neurodegenerative Diseases
Since the brain is the only organ in the body that maintains our memories and personality, it cannot simply be replaced if it begins to deteriorate. This presents a unique challenge for life extension since the knowledge stored in the brain needs to be protected from sickness and injury for long periods. Naturally, it is advantageous to stop neurons from dying too soon. Neurons can perish due to poisons like alcohol, accidents like strokes, and illnesses like Alzheimer’s. Controlling the chemistry within the cell can significantly slow down, if not completely stop, neuron death in each of these scenarios. You can vacuum up harmful compounds and change them into safe ones.
