TLDR
A series of metal complexes of Cu(II) and Ni(II), having the general composition [M(L)X2] with benzil bis(thiosemicarbazone) has been prepared and characterized by element chemical analysis, molar conductance, magnetic susceptibility measurements, and spectral (electronic, IR, EPR, mass) studies as mentioned in this paper.Abstract:
A series of metal complexes of Cu(II) and Ni(II) having the general composition [M(L)X2] with benzil bis(thiosemicarbazone) has been prepared and characterized by element chemical analysis, molar conductance, magnetic susceptibility measurements, and spectral (electronic, IR, EPR, mass) studies. The IR spectral data suggest the involvement of sulphur and azomethane nitrogen in coordination to the central metal ion. On the basis of spectral studies, an octahedral geometry has been assigned for Ni(II) complexes but a tetragonal geometry for Cu(II) complexes. The free ligand and its metal complexes have been tested in vitro against a number of microorganisms in order to assess their antimicrobial properties.read more

Antimicrobial surface modification of titanium substrates by means of plasma immersion ion implantation and deposition of copper
TL;DR: Antimicrobial equipped surfaces of titanium (Ti–6Al–4V) implants are beneficial to prevent implant-associated infections of total joint endoprostheses and osteosyntheses and Copper (Cu) is well suited for this purpose, since it exhibits a well-known antimicrobial activity.
