Shanghai's development of "nanodetectors" will shorten the time of diagnosis of hepatitis and other diseases

acute myocardial infarction is adiseasewith a high mortality rate, the most critical in the treatment process is to be diagnosed early, the current routine diagnosis of acute myocardial infarction to 40 minutes, and now, "nanodetector" is expected to heart attack, AIDS, hepatitis and other majordiseases
the time of diagnosis ofgreatly shortenedYesterday, from the Shanghai Jiaotong University learned that the multi-functional biomedical tool known as "nanodetector" - nanomagnetic microspheres in the university's Institute of Micro-nano Science and Technology prepared successfully, a series of majordiseasesdetection is expected to be faster and more accurate" The name of the nanodetector is "single-dispersed high-magnetic responsive nanomagnetic microsphere", the total amount of magnetic particles containing each microsphere is more than 70%, under the action of magnetic field, a large number of nanomagnetic microspheres can accurately "grab" the detection object, and "concentrated transport" to the designated location, quick detection outAccording to experts, this technology has a wide range of applications, can be used to quickly detect hepatitis, AIDS, myocardial infarction and other biomedical fields, but also to participate in Sudan red, pesticide residues and other food safety testingIn addition, it can replace expensive imported reagents and reduce the cost of medical care for patientsAt present, Shanghai Jiaotong University to magnetic microsphere magnetic signal instead of the current disease detection commonly used optical signals, so that the HIV, hepatitis B virus, hepatitis C virus and other major infectious diseases detection sensitivity increased 10 to 100 timesAt the same time, the entire detection time is reduced to only about 20 minutes to obtain quantitative results(rereproduced from News Evening News)
