New Sensing Method Expands Label-Free Particle Detection
Researchers are advancing particle detection technologies to find rare targets like viruses and circulating tumor cells in complex biological samples. Finding single cancer cells in blood remains a major challenge, driving the demand for ultrasensitive and robust sensors. New methodologies aim to overcome traditional surface-bound limitations by expanding label-free detection capabilities. This progress could significantly enhance diagnostics and real-world sample analysis.
