By packaging gadolinium contrast agents inside nanoparticles with target-responsive water channels, a single target molecule can activate many contrast agents at once, achieving roughly tenfold greater sensitivity than conventional one-to-one sensing approaches. Tested in living rats to detect biotin, the sensors can be delivered systemically and spread throughout the brain, making them promising for whole-brain imaging of neurochemicals like dopamine and glutamate. ## Full article daily.dev links to this article rather than hosting it.
