Using tailored nanodiamonds with negatively charged silicon-vacancy (SiV<sup>-</sup>) color centers we performed a series of intracellular experiments. These nanodiamonds with SiV<sup>-</sup> centers (NDs-SiV<sup>-</sup>) were obtained by high-pressure high-temperature (HPHT) synthesis based on metal catalysts-free hydrocarbon HPHT growth. They were coated by a polypeptide biopolymer allowing efficient cellular uptake. High photostability and narrow emission in the near infrared region allows tracking of functionalized NDs-SiV<sup>-</sup> in living cells. The excellent optical properties render NDs-SiV<sup>- </sup>promising nanoemitters for various bioimaging applications. Furthermore, cellular tracking with detailed time, spatial, and spectral information paves the way to intracellular thermometry based on NDs-SiV<sup>-</sup>.

Allylether-Rhodamine selectively invites Pd2+from mixture of other cations and Pd(0) in H2O-MeCN medium and exhibits maroon emission due to C(allyl)-O bond cleavage and opening of spirolactam ring. The LOD is 50 nM at pH 7. Imaging Pd2+species in living cells under physiological conditions is achieved.
