Computational calculations using density functional theory(DFT) were performed for the first time using the full potential linearized augmented plane wave plus local orbital method(FP-LAPW + LO) to determine the structural, elastic, electronic and magnetic properties of europium-based cubic perovskites EuYO_(3)(Y=Cr, Mn, Fe). The exchange correlation potentials of GGA along with some analytical methods were adopted for the computation of structural and elastic properties. Moreover, the GGA + U formalism was also added for obtaining more precise electronic and magnetic properties, particularly to address the Eu-4f and Y-3d orientations in the spin-polarized double cell symmetry. The observed lattice parameters of these compounds are consistent with experiment. The observed bulk moduli predict that EuCrO_(3) is harder and less compressible than EuMnO_(3) and EuFeO_(3). The calculated tolerance factors of these compounds are within the cubic symmetry range. Our computed critical radius of EuCrO_(3) shows that EuCrO_(3) has a larger migration energy. Based on their elastic properties, these compounds are ductile in nature. We also computed the thermal properties of these compounds. The band structures and density of states show that these compounds are metallic in character. The lowest ground state energy and magnetic moments of these compounds expose their ferromagnetic nature. The metallic nature and strong ferromagnetism of these compounds make them promising applicants for application in spintronic.

Complete fusion of two selected ceils allows for the creation of novel hybrid cells with inherited genetic properties from both original cells. Alternatively, via fusion of a selected cell with a selected vesicle, chemicals or genes can be directly delivered into the cell of interest, to control cellular reactions or gene expression. Here, we demonstrate how to perform an optically controlled fusion of two selected cells or of one cell and one vesicle. Fusion is mediated by laser irradiating plasmonic gold nanoparticles optically trapped between two cells （or a vesicle and a cell） of interest. This hot-particle-mediated fusion causes total mixing of the two cytoplasms and the two cell membranes resulting in formation of a new hybrid cell with an intact cell membrane and enzymatic activity following fusion. Similarly, fusion between a vesicle and a cell results in delivery of the vesicle cargo to the cytoplasm, and after fusion, the cell shows signs of viability. The method is an implementation of targeted drug delivery at the single-cell level and has a great potential for cellular control and design.
