Highly Sensitive and Selective Label-Free Optical Detection of Mercuric Ions Using Photon Upconverting Nanoparticles

We demonstrate a fluorescence-based, label-free detection scheme that reports the presence of Hg(II) ion using photon upconverting nanoparticles. A single-stranded DNA containing a number of thymine bases to be used as the Hg(2+)-capturing element is covalently attached to the photon upconverting Na...
