New estrogen real-time detection sensor available
As scientists have developed a new generation of sensors to facilitate patient monitoring, scientists from New Zealand have also introduced a new type of sensor device that can help detect estrogen levels in the body without carrying the shortcomings of current technology. And the drawbacks. Researchers from the University of Wellington in Victoria say that when the new sensor detects body hormones, it can send a signal to screen for lower levels of estrogen in the fluid, and the sensor traps small pieces of DNA-aptamers ( Aptamers) come into play, and aptamers can “tighten†estrogen molecules. This nanotube-like sensor device is like a transistor, and if an estrogen molecule is present, it emits an electrical signal. The researchers examined the two lengths of the device in a biological fluid, one of which was 35 cells long and the other 75 cells long. It was found that shorter length sensor devices can generate electrical signals for use. Mark the presence of estrogen. Longer sensor devices do not induce electrical signals, perhaps because their surface is difficult to promote aptamers to capture estrogen molecules to produce electricity. The study was published in the international journal Journal of Vacuum Science & Technology B. In a statement, the researchers pointed out that the new sensor device offers an advantage for traditional screening methods, and it includes a simple design of a real-time reader that consumes less energy and can also be electronically monitored. The system is used in combination. Next, the researchers plan to test the device in real biological fluids (such as urine), and researchers are also very concerned about the different applications of the technology, such as considering the use of this device to screen not only estrogen molecules. Researcher Professor Natalie Plank said that aptamers may be a potentially powerful tool for sensors because of their versatility and selectivity, and he believes that the research team will eventually develop a device for other molecules and more diagnostic techniques. application.
