Sensing Sensitivity

In this paper, we found that sensing sensitivity increases with decreasing the particle size, which was confirmed by the Judd–Ofelt theory.

U2os Cells

Blue emitting, up-converting NP's of SrTiO3:Tm3+/Yb3+ synthesized using the citric route are biocompatible towards J774.E whereas the cytotoxic effect to U2OS cells is not particle size dependent but most probably is related to Sr2+ ion release.
