We present the first experimental search for the rare charm decay ${D}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}\ensuremath{\nu}\overline{\ensuremath{\nu}}$. It is based on an ${e}^{+}{e}^{\ensuremath{-}}$ collision sample consisting of $10.6\ifmmode\times\else\texttimes\fi{}{10}^{6}$ pairs of ${D}^{0}{\overline{D}}^{0}$ mesons collected by the BESIII detector at $\sqrt{s}=3.773\text{ }\text{ }\mathrm{GeV}$, corresponding to an integrated luminosity of $2.93\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$. A data-driven method is used …
