摘要: In the latest issue of Nature Nanotechnology, Ling and coworkers reported the first potassium nanosensor applicable in a freely moving animal. It was developed by embedding the mesoporous silica nanoparticle framework with optical potassium indicators and then shielding the framework with an ultrathin layer of a potassium-permeable membrane. This nanosensor achieved highly sensitive monitoring of the dynamic changes of the extracellular potassium in the brain of freely moving mice with epilepsy.
