Nano cure: Promise treatment is over

After being vaccinated with nanotechnology, rats with polio were again active. Scientists hope nanotechnology will cure many kinds of incurable diseases such as spinal cord injuries, polio, heart failure, stroke, diabetes, Parkinson's . and even cancer!

American scientist Samuel Stupp, of Northwestern University, Illinois, said nanotechnology is opening up a promising prospect in treating many diseases, such as spinal cord injuries, polio, heart failure, and stroke. stroke, diabetes, Parkinson's disease (chronic neurological disease that causes the muscles to vibrate and weaken) and cancer too.

At a scientific forum held in Washington, USA, Professor Stupp stressed that nanotechnology - the technology that uses ultra-small, atomic or molecular-sized materials - could be Help regenerate damaged organs or tissues, thereby successfully treating many different diseases.

Nano: Great hope

In the report "Nanoscale: Vision for the future of nanotechnology" (NanoFrontiers: Visions for the Future of Nanotechnology) published at the forum, Professor Stupp said that after six weeks, a solution of cells is injected. Using nanotechnology to regenerate nerve cells, mice that are paralyzed because of spinal cord injury have completely restored their ability to manipulate the limbs.

This solution consists of molecules designed to form tissues that, after injury, cannot heal themselves or cannot replicate themselves - like bones and nerve cells.

"By injecting molecules designed to assemble themselves into nanostructures in spinal cell tissue, we were able to repair and regenerate damaged neurons," he said. To illustrate this important study, he showed at the forum a video showing the condition of mice before and after treatment.

Professor Stupp hopes that clinical trials of human spinal cord injury will be done by his team within the next few years. The team has also done many tests that show that mice with symptoms of Parkinson's have fully recovered after being treated with nanotechnology.

He said: 'We are extremely excited because the results of this study have opened up a new direction in the treatment of neuron degeneration'.

In addition, by using injections containing nanostructures and proteins, the team also succeeded in restoring the heart function of mice with heart attack.

In addition, the team is using nanotechnology to create a " Trojan horse " drug - located underground in the cell waiting for the chance to attack cancer cells without risking it could be as treatment with chemotherapy.

Stupp said nanotechnology treatment hardly caused side effects.

US: 144 million USD put nano into medicine

Professor Stupp also said the new drug he designed does not contain germ cells, ie stem cells derived from human embryos can form many different types of cells. But he said that stem cells could help enhance the effectiveness of nanotechnology treatments.

David Rejeski, Director of the New Nanotechnology Project, said: 'This research opens up a new development in the field of exciting and new nanotechnology applications.'

The American Cancer Research Institute is devoting a $ 144 million five-year budget to study the applicability of nanotechnology in cancer detection, monitoring and treatment. The US government is also spending $ 1 billion annually on nanotechnology development.

The US Environmental Protection Agency said projects to research the safety of nanotechnology are 'one of the government's top priorities'.

The study by Professor Stupp and colleagues has just been published in the journal Science, and the group's latest results on nanotechnology applications in medical treatment will continue to be presented in this journal. .
