DETECTION METHOD AND SENSOR BASED ON INTERPARTICLE DISTANCE

摘要

The present invention relates to a method for determining the presence or amount of a compound in a sample by interparticle distance-dependent sensing, comprising:(a) contacting the sample suspected of containing the compound with rare earth doped metal oxide nanoparticles; and(b) detecting the compound by determining the change in luminescent properties of the rare earth doped metal oxide nanoparticles upon contact with the sample.
