Tumours illuminated brightly and precisely with new biodegradable nanoprobe – Science Codex

To highlight tumours in the body for cancer diagnosis, doctors can use tiny optical probes (nanoprobes) that light up when they attach to tumours. These nanoprobes allow doctors to detect the location, shape and size of cancers in the body.
Most nanoprobes are fluorescent; they absorb light of a specific colour, like blue and then emit back light of a different colour, like green. However, as tissues of the human body can emit light as well, distinguishing the nanoprobe light from the background…
