Biosensor for diagnosing cancer
Release date: 2016-08-19
If you can diagnose the condition of cancer patients early, it is very beneficial for their treatment. At present, biopsy and blood testing are the main means of screening for cancer patients, but in this process the samples must be sent to the laboratory, which takes time. It is laborious and expensive, and the means of taking it is invasive for the patient.
New biosensors recently developed may provide inexpensive, convenient, and accurate inspection services. Biosensors are rapidly emerging in research, characterized by rapid, sensitive and stable, but few devices can be put into clinical use.
Scientists at the University of St. Paul and the University of São Paulo have recently collaborated to develop a new device for early diagnosis of cancer. The project is led by Dr. Pedro Estrela and Professor Marcelo Mulato to achieve early diagnosis by measuring specific cancer cell targets in the blood. .
The researchers integrated core components based on electronic chemistry and semiconductors. The two schools have expertise in each other, using their disciplinary advantages to improve the sensitivity and selectivity of detection equipment. They found this biosensor for prostate cancer and breast. Cancer diagnosis efficiency is relatively high, Dr. Estrela said: "In the UK, the incidence of these two cancers is high, and early examination can increase the success rate of treatment to reduce the mortality of patients. Because the early symptoms are not very obvious, find a kind of disease. Effective diagnostic methods are critical."
This new way of checking can change the lives of patients. In addition, they are developing another type of detection device that uses the principle of detecting microRNAs in the blood, which is closely related to the occurrence and evolution of cancer, which uses molecularly imprinted Means provide relevant information for the classification and staging of prostate cancer, and this information can help us find the best treatment.
Finally, this device is less harmful and more effective than other devices, and it is more accurate for some markers in the blood. We hope that this biosensor can be widely used in the world in the future.
