摘要:
Quantum converting nanoparticles for electric field sensing are provided. In one example, by combining upconverting lanthanide ions with voltage responsive dyes, we generate an optical platform that displays intensity and spectrum changes in the presence of electric fields. Our particles enable local (down to 10 nm spatial resolution) mapping of electric fields with exceptional photostability. We can image and quantify in vivo and in situ electric fields in biological and material systems up to fields of ˜100 kV/cm.
