How Nanotechnology is playing a significant Role in Health Sector?


INTRODUCTION:

Nanotechnology is the study of small objects that can be used in other fields of science like chemistry, material science, biology, and physics, etc. For the drug delivery system, nanobiotechnology has high potential and many biomedical applications. In medicine, nanotechnology applications are playing a significant role in drug targeting, molecular imagining, disease diagnosis, etc. In order to prevent and treat different kinds of diseases, nanotechnology is playing an important role in recent years. The drug delivery methods route of the administration is commonly used for the delivery of the active molecule, but it has many disadvantages related to this system. In the diverse fields, nanotechnology and nanoengineering stand to produce technological advancement. For the applications in physiology and the medicine, these devices can be designed, and they can coordinate with the target tissue and the target cells.

APPLICATIONS IN THE DRUGS NAD THE MEDICINES:

Nanotechnology can deliver the drug into the different parts of the body and make them less harmful to the other parts of the body system. Anti-cancer gold nanoparticles are used against cancer. These particles have the ability to absorbs the radiations at a specific wavelength. When they are entering into the human body, the radiation treatment is supplied to the human. The heat-up and absorb energy, which is enough to kill the cancer cell. Instead of the gold other nanoparticles are also used in this treatment.

APPLICATIONS IN THE DRUG DELIVERY:

For the site-specific delivery of the drugs, nanoparticles are used. For this purpose, dendrimers and nonporous materials are used. For the active delivery of the drugs, the electrochemical systems are used. For this required drug dose is needed, and the side effects are decreased by the active depositing agents in the morbid region. It can low the pain and cost of the patients.

APPLICATIONS IN THE SURGERY:

On any part of the body, micro-surgeries has been performed by using the robots and minute surgical instruments. Other applications may be damage the whole body. These minute instruments can target only the small part of the body as they are accurate and precise. In the surgery visualization can also be improved, computers are used to hold the instruments. Nanocameras that are used in the surgery can provide a close view of the surgery.

APPLICATIONS IN THE CANCER:

As these particles have a high surface to volume ratio, they permit may kind of the functional groups to attached top the nanoparticles, which can bind to the different cancer cells in the body. The small size of the nanoparticles allows them to bind with the specific cancerous site. In cancer, nanoparticles can overcome the problem of selectivity, solubility, and drug resistance.

APPLICATIONS IN THE MEDICAL ROBOTICS:

As the nano-robotics have vast applications in the other fields, they are also playing a significant role in the medical field. Their applications include drug treatment, early diagnosis, biomedical instrumentation, access to diabetes, and health care. Next, these nano-robotics can inject into the human body into the cell level.

APPLICATIONS IN THE THERAPEUTICS:

Nanomachines containing mouthwash are used that can target, identify, and kill the pathogenic bacteria. For the remote control nanomaterials, it can identify the subocclusal surface in the patient’s teeth near the gum-line.

APPLICATIONS IN PASSIVE IMPLANT AND TISSUE ENGINEERING:

All the joints, such as hips, complications will happen after the age of 10 to 16 years; nanotechnology is helpful for reducing these kinds of problems. The alloys, cobalt, and titanium are used to make implants, which are harder and smoother for wearing constantly. This layer ensures that the body is better compatible with the implants. Nanofibers are biodegradable as they are consist of the organic and synthetic polymers, and they are used for cultivating other tissues like nerve tissues, muscle tissue, and vascular tissue, etc. All kinds of patients that have brain damage they are blind, their sight will be restored in a few weeks by injecting the nanomaterials in their brain. Small tubes are used for the implants, and they are called the stents. When we use the lead in the stent, the problem happens blood vessels will be closed to overcoming this. We can use the aluminum oxide nanoparticles, which also provide the nanopores. These pores can be confirmed that a sufficient amount of the radioactive material can be introduced. For avoiding clotting in the blood, the researchers are using the titanium compounds. This will change the conformation of the protein.

APPLICATIONS IN THE ACTIVE IMPLANTS:

Implants that contain the energy source are called active implants. On the basis of there function, they can divide into the two major groups. In the first group, implants, are included, such as morphine pumps and insulin pumps that are used for a long duration. For controlling the release of active substances and their storage, the microchips are used, which include the facts that the chips are going to the original location. Neural prostheses are included in the second group. This involves the restoration of hearing implants, implants that regulate the heartbeat, deep brain stimulator, etc. They are used for several years. Retinal implants are used to restore the sight in the patients.

OTHER APPLICATIONS DISINFECTION:

Silver is used as a disinfectant. Due to the increasing resistance of the bacteria to antibiotics, the concept of using silver as a disinfectant is renewed. In the working mechanism, silver nanoparticles are extremely used as these particles are integrated with the fibrous and globular proteins. In the market, nanocrystalline silver is already present.they are also useful for reducing infections.

CONCLUSION:

Nanotechnology is the study of small objects that can be used in other fields of science like chemistry, material science, biology, and physics, etc. For the drug delivery system, nanobiotechnology has high potential and m, any of biomedical applications. In medicine, nanotechnology applications are playing a significant role in drug targeting, molecular imagining, disease diagnosis, etc. In order to prevent and treat different kinds of diseases, nanotechnology is playing an important role in recent years. The drug delivery methods route of the administration is commonly used for the delivery of the active molecule, but it has many disadvantages related to these systems. In the diverse fields, nanotechnology and nanoengineering stand to produce technological advancement. For the applications in physiology and the medicine, these devices can be designed, and they can coordinate with the target tissue and the target cells.
