DNA nano robot system is one of the nano machines, and has been continuously developed in recent years. In recent years, in the journal Science, we saw another "feat" realized by DNA nano robot - researchers used electric field to accelerate the movement speed of DNA robot system.
It is reported that researchers from Georgia Institute of Technology and Piemonte Heart Institute are using customized 3D printed heart valve models based on patients' heart CT scanning to improve the success rate of transcatheter aortic valve replacement (TAVR) surgery. Their aim is to avoid perivalvular leakage. This research has been published in JACC: Cardiovascular Imaging.
Stroke is the main cause of disability in Americans. More than 6.5 million Americans survive stroke every year, and most of them cannot fully recover their walking ability. Experts said that because of the difficulty in walking, these patients would not even go out to the store to buy things, but they were inactive for a long time, which led to other health problems and a spiral decline in their quality of life.
When it comes to the breath detector, everyone will think of the thing used by the traffic police to check drinking and driving. For those who drink and drive, they will lose their temper when they see the breath detector. In fact, the gas exhaled by the human body has many characteristics. It can not only detect alcohol, but also reflect the health of the human body and detect some diseases. This breath detector introduced in this article can detect breast cancer, diabetes, lung cancer, Parkinson's disease, asthma, schizophrenia, kidney and liver failure and other diseases.
Scientists from MIT designed a microfluidic device to capture and count circulating plasma cells in small samples of blood. This technique can only be carried out through routine blood drawing, which is expected to reduce the pain of patients' myeloma testing.
In a rural area of Britain, a team of 100 scientists and engineers first used low-cost technologies to develop mobile phones and the aviation industry. Later, these technologies were used to research robot arms, which can be specially used for minimally invasive surgery.
Recently, Nassim Annabi, an assistant professor of Northeastern University in the United States, and other researchers from the University of Sydney in Australia jointly developed an advanced surgical glue MeTro. When using, the glue directly enters the wound and is solidified and sealed within 60 seconds. Naxim said, "The advantage of MeTro formula is that once it touches the organ, it will appear as gel instantly and will not slip."
According to Telegraph, a new study shows that human doctors will still outperform "robot doctors" in surgery. Compared with robots, human doctors need shorter time to complete surgery, and the error rate is not high.
As more and more organisms become resistant to antibiotics, the threat to human health is increasing. The overuse of antibiotics leads to drug resistance. It is very important to limit the use of antibiotics. The research team of the University of Alberta in Canada has recently developed a hand-held detection instrument, which allows first-line clinicians to distinguish between patients with viral infection or bacterial infection within a few minutes, thus helping to reduce unnecessary antibiotic prescriptions and overuse of antibiotics. Because antibiotics are only effective for bacteria, if the patient is infected with virus, there is no need to prescribe antibiotics.
Medical engineers at Walter Reed National Military Medical Center are using additive manufacturing to develop customized prosthetic solutions for veterans. In fact, the center is even operating a 3D Medical Application Center (3DAC). There, a team of specialized engineers and 3D printing technicians are developing customized equipment according to the requirements of veterans.
