Nanosensors Can Detect Early Signs of Cancer

Nanosensors Can Detect Early Signs of Cancer

         According to recent study conducted by the Yale Institute for Nanoscience and Quantum Engineering located in New Haven, Connecticut, nanasensors have the ability to detect early signs of cancer in blood samples taken from patients.

          The sensors had the ability to detect biomarkers for prostate cancer as well as breast cancer.

          Through this finding, researchers are hoping to make a low-cost cancer test that can be conducted in a doctor's office to detect cancer. If such a test is developed, then patients would just need to have a pinprick on their finger and the result will be available within a few minutes. Above all, the test would be simple and quite inexpensive to conduct. So, more number of people would be able to have early cancer tests and start treatment early. As we know that the survival rate of cancer patients depends on early detection of the disease.

           The good news is that the nanosensors can be modified for other types of cancer biomarkers. This way, cancers of the lung, pancreas or ovary can be detected early and treated accordingly. In fact, the early detection will ensure better prognosis for these cancers as they are quite aggressive and difficult to treat.

          According to the researchers, just a small amount of blood is required for detecting the biomarkers and the results were available within 20 minutes.

           At the moment, not many cancer biomarkers have been identified. However, researchers are optimistic that more will be identified through the Human Genome Project. As more proteins are identified, researchers will be able to link it to a gene, which, in turn, can be linked to a particular type of cancer.

           So, although this test is still some time away in making it to a doctor's office, the initial findings are extremely useful.
