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 the body's estrogen levels without the disadvantages of the current technology And disadvantages. Researchers from the University of Victoria, Wellington, said that when the new sensor detects body hormones, it can screen for lower levels of estrogen in the fluid by sending electrical signals through the DNA-aptamer Aptamers), aptamers can "grip" estrogen molecules. This nanotube-like sensor device acts like a transistor, releasing the electrical signal if estrogen molecules are present. Researchers tested two lengths of this device in a biological fluid, one of 35 cells long and the other 75 cells long. As a result, shorter length sensor devices were found to produce electrical signals that could be used Marked the presence of estrogen. Longer sensor devices do not induce electrical signals, perhaps because the surface is difficult to promote aptamers to capture estrogen molecules and create electrical currents. The study was published in the Journal of Vacuum Science & Technology B. The researchers pointed out in a statement that the new sensor device offers an advantage over traditional screening methods and includes a simple-to-design real-time reader that consumes less energy and is also electronically monitored System used in combination. Next researchers plan to test the device in real biological fluids, such as urine, and the researchers are very concerned about the different applications of the technology, such as considering using the device to screen more than just estrogen molecules. Researcher Natalie Plank said that aptamers may be a potentially powerful tool for sensors because of their versatility and selectivity, and he believes the team eventually will either develop a device for other molecules and more diagnostic techniques application.
