New sensing method expands label-free particle detection beyond sensor surfaces

Finding a single cancer cell in a tube of blood is a bit like finding a needle in a haystack. As researchers seek to detect ever-smaller and rarer targets, from viruses to circulating tumor cells in blood, the demand for ultrasensitive, robust sensors that are practical for real- This story matters for Science & Discovery readers tracking science.
