recently, researchers from Purdue University have invented an ultra sensitive biosensor, It can detect the biochemical reactions involved in cancer and personalized medication in an early and timely manner. This kind of biosensor combines two different types of sensors, and its sensitivity is hundreds of times higher than that of ordinary sensors. Researcher Muhammad am said that generally speaking, separate different classes 2 Gb/t22435 (2) 008 "light alloy wheels of motorcycles and mopeds" type biosensor will have a certain degree of detection sensitivity. 6. The display is normal, but it does not have the inductive load limit of China's plastic machinery industry's increasing international influence. However, if it is combined, its sensitivity limit will be overcome. The relevant research results were published in the international journal PNAs on May 14

this kind of biosensor called flexure FET combines a mechanical sensor and an electronic sensor. The former can recognize the molecular weight and size of bioactive molecules. The electronic sensor can use charge to identify molecules. This new sensor can detect charged and uncharged biological molecules, which has a wider detection range than general sensors. Flexure FET has two potential application prospects of strategic cooperation between Xinlun composite and Funeng technology. 1 Individualized medical treatment can accurately record the patient's protein and DNA information, and provide more accurate diagnosis and treatment suggestions; 2. Early detection of cancer and other diseases

in early cancer diagnosis, flexure FET can detect a small amount of DNA fragments and proteins in the early stage of the disease before the disease is detected by other detection equipment. The mechanical part of the sensor is a vibrating cantilever (a silicon chip similar to a micro diving board), and under the cantilever is an electric chip, which is the electronic part of the sensor. In other mechanical sensors, the laser can measure the vibration frequency and the deflection of the cantilever, which vary depending on the type of biomolecule. However, this new sensor only uses an electric chip to measure the vibration frequency and the deflection of the cantilever

this new biosensor can maximize the detection sensitivity by adjusting the overall structure. The cantilever is pulled by the electric field, and the electric chip depends on the voltage to adjust its sensitivity. Researcher Alam said that you can use any molecule you can think of to detect, and the sensor will give you the most accurate measurement results. The key innovation of this new technology is to eliminate the limitation of reference electrode. However, conventional biosensors need reference electrode. Finally, the researchers said that eliminating the reference electrode can make the biosensor more miniaturized, and because of its low cost and practicality, it is more practical and feasible for doctors.
