U.S. scientists: Nanotechnology can help improve accuracy in cancer diagnosis

, U.Sscientistspublished a studyTuesday, sayingusing nanotechnologyhelp doctors improve the accuracy of cancer diagnosis by comparing the elastic itys of cancerous cells with the elasticity of normal cellsResearchers at the University of California took samples from patients with suspectedtumorsput them under nanoscale microscopesThe researchers used a probe to apply a weak voltageto each cell in the sample,the other end of the probe connected to a robotic armThe researchers found that the surface elasticity of cancerous cells was 70 percent softer than normal cellsThey believe the findings could be used to help doctors improve the accuracy of cancer diagnosesAt this stage, there are two main ways to diagnose cancer in the medical community: one is a live slice, the cut tissue is placed under a microscope to see if there are signs of cancer, and the other is to use antibody testing of proteins to distinguish between cancerous cells and normal cellsBut previous studies have shown that these diagnoses are less than 100% accurate, and the average margin of error in using both methods to test lung cancer is 15%James Janmeski, who led the study, said that when normal cells become cancerous, shape and internal structure change, and cancerous cells become softer But this feature cannot be found by comparing the cell shape " Our study shows that instruments analysis can distinguish cancer cells from normal cells, even if they sometimes appear in the same shape," Janmeski said The study was published in the British journal Nature Nanotechnology
