Carbon nanotubes permanent prosthesis using life up to 150 years (1)

"Carbon nanotubes" (carbon nanotube) of Japan NEC company researchers in 1991 using electron microscope observation of graphite globular arc equipment generates carbon molecules is accidental discovery of a tubular coaxial nanotube carbon molecules composed of materials.

Carbon nanotubes are divided into single carbon nanotubes and multiple layers of carbon nanotubes. Studies show that carbon nanotubes with Super strength, fatigue resistance and good electrical conductivity. In recent years, the United States led by developed countries on carbon nanotubes that new materials for industrial applications for a number of exploratory research, and found it in the field of medical devices have good prospects.

Carbon nanotubes permanent prosthesis

Prosthesis (such as artificial limbs, prosthetic, etc.) and product use is quite common.

However, the vast majority of prosthesis can only use 10 to 15 years. Since then, patients and to accept second surgery to replace the prosthesis. Spain National Medical Research Institute of two PhD developed a zirconium oxide surface for the base material, coated with carbon nanotubes series new prosthesis, including artificial knee joint, artificial 髖 joints, such as denture, its life up to 150 years. In other words, once the implantation of the prosthesis, patients do not need to replace it again.

Zirconia is a variety of artificial ceramic materials of main components, the drawback is easy to wear.

Spain researchers use special spray technology will carbon nanotubes spraying in the bio-ceramic implant surface, is to put on a wearable "tight".

Carbon nanotubes biosensor

At present, many countries in the world of scientific research institutions are actively developing rapidly detect the presence of tumor cells in the body of new biological sensors.

There is a biological sensor of the external surface coated with a layer of carbon nanotubes, it has cancer specific advance adsorption, the patient's antibodies in a blood drop in such biosensors, cancer cells will rapidly and antibody response. Doctor through special optics can be observed from this response to determine whether the patient has a number of cancer cells and cancer cells. This new type of carbon nanotubes very high biological sensor sensitivity may be early cancer diagnosis of many.

Carbon nano-tube screen materials

United States-Michigan State University Institute for advanced materials developed a neutral carbon nano-tube screen and new materials.

This mesh material, the circuits and nerve cells connected together, can be used to control pain, for example for terminal cancer patients, burn and serious car accident victims and other conventional painkillers are difficult to play the role of severe pain patients.

Researchers said that the use of carbon nano-tube screen not only manufactures Implantable devices and electronic pain, or even to tell a very faint nerve issue, so use this current of new material can also produce control seizures and control muscle contraction of new electronic products, medical devices, such as older women with urinary incontinence and the treatment of Parkinson's disease and other equipment.

Carbon nanotube-Coated electrodes implanted

Use of implanted electrodes electrical pulse signal, can be treated with a variety of nervous system diseases and mental illnesses such as depression, Parkinson's disease, epilepsy, etc.

But existing implanted electrodes for metal products, their working life. In order to overcome this technical problem, United States of Texas researchers conducting in-depth research. They found that in the implanted electrodes on the surface layer of carbon nanotube materials, implanted electrodes of working life has been significantly extended. New development of carbon nanotube-Coated electrodes implanted in the primate experiments on has achieved satisfactory results.
