“…The literature presents information on the use of Co (II) ions as an antibacterial and antiviral agent in various organic complexes [ 136 , 137 ]. In 2013, two elaborations were developed concerning hydroxyapatites partly doped with cobalt ions (II) [ 138 , 139 ].…”

Reconstructive surgery is presently struggling with the problem of infections located within implantation biomaterials. Of course, the best antibacterial protection is antibiotic therapy. However, oral antibiotic therapy is sometimes ineffective, while administering an antibiotic at the location of infection is often associated with an unfavourable ratio of dosage efficiency and toxic effect. Thus, the present study aims to find a new factor which may improve antibacterial activity while also presenting low toxicity to the human cells. Such factors are usually implemented along with the implant itself and may be an integral part of it. Many recent studies have focused on inorganic factors, such as metal nanoparticles, salts, and metal oxides. The advantages of inorganic factors include the ease with which they can be combined with ceramic and polymeric biomaterials. The following review focuses on hydroxyapatites substituted with ions with antibacterial properties. It considers materials that have already been applied in regenerative medicine (e.g., hydroxyapatites with silver ions) and those that are only at the preliminary stage of research and which could potentially be used in implantology or dentistry. We present methods for the synthesis of modified apatites and the antibacterial mechanisms of various ions as well as their antibacterial efficiency.

“…The remarkable fluorescence quenching of HL upon complexation with the aforementioned metal ions (M:L = 1:2) may be attributed to decrease in electron density on Schiff base [32,33]. On the other hand, the fluorescence spectra of Zn(II) (1d) and Cd(II) (1e) complexes show enhanced emission compared to HL upon excitation at 378 nm and 371 nm respectively [28,29]. In this case the complexation occurs via 1:1 ratio of Metal to ligand.…”

A series of Cu(II), Co(II), Ni(II), Zn(II) and Cd(II) complexes of (E)-2-(5-chloro-2-hydroxybenzylidene)-N-(4-phenylthiazol-2-yl)hydrazinecarboxamide (HL) with ONO donor ligand was synthesized. The ligand (HL) was prepared by the condensation of N-(4-phenylthiazol-2-yl)hydrazinecarboxamide with 5-chloro-2-hydroxybenzaldehyde. The HL and its metal complexes have been characterized using elemental analysis and various spectral techniques such as, FTIR, 1H and 13C NMR, Mass, UV–Visible, ESR, thermal analysis (TGA), magnetic moment, conductivity and powder-XRD. The Powder XRD pattern indicates hexagonal or tetragonal system for HL and its metal complexes. The fluorescence studies exhibits strong emission in the range of 400-500 nm for HL. Further in comparison the HL, Zn(II) and Cd(II) complexes showed enhanced emission whereas Cu(II), Co(II) and Ni(II) showed poor emission. The antimicrobial activities of the HL and its metal complexes were studied by minimum inhibitory concentration (MIC) method wherein the metal complexes showed better activity as compare to free ligand.
