“…Our previous work reported that the doping of PIn with perchloric acid (HClO 4 ) could improve its electrical conductivity by many orders of magnitude to support various electronic applications. 34 Recently, PIn was applied as an antifungal material for the fungi Penicillium chrysogenum 35 and as a capacitor, 36 humidity sensor, 37 methanol sensor, 38 etc. Furthermore, PIn-composited graphene based materials can be applied in various electronic applications; for example, GO/PIn composite was utilized as a supercapacitor, 36 GO/PInincorporated Ag was applied as an electrode material, 39 and rGO/PIn nanocomposite was used as a capacitor.…”

“…In addition, Devadathan and Raveendran (2014) worked on polyindole-based nickel-zinc oxide nanocomposites to identify the antifungal properties, and they proved that a non-composite could be used as an antifungal material for the fungi Penicillium Chrysogenum (45). However, the use of animal models, as well as various treatment methods and nanoparticles with different concentrations and shapes, presents new horizons for further research to investigate the applications of nanotechnology (46).…”

Background: In recent years, bioactive bioceramics such as bioglass and hydroxyapatite (HA) have been introduced as a remarkable development in the field of medicine due to their bio-adaptability, non-toxicity, and persistence, in vivo. They have many potential applications in the repair of bone defects and hence they have attracted significant interest from scholars. Objectives: The aim of this study was to synthesize inorganic matrix CuO-based bioglasses and evaluate their antibacterial activity against aerobic bacterial infections in bone implants. Methods: Nano-composite samples of silica-based bioactive glass, 60S BG with nano-powder CuO, were synthesized using the sol-gel method and then assessed with regard to their antibacterial properties against Staphylococcus aureus using well diffusion agar. The samples included BG58S (58%SiO2, 36%CaO, 6%P2O5), BG/10CuO (58%SiO2, 26%CaO, 6%P2O5, 10%CuO), and BG/20CuO (48%SiO2, 26%CaO, 6%P2O5, 20%CuO). To evaluate their bioactivity, the prepared samples of BG/20CuO, BG/10CuO, and BG58S were immersed in simulated body fluids (SBF). The surface morphology and structure of the samples before and after immersion in the SBF were characterized using scanning electron microscopy (SEM) and Fourier transform infrared (FTIR), respectively. Then, the BG/20CuO and BG/10CuO samples were loaded in clindamycin, an antibiotic widely used in the treatment of osteomyelitis, and their release profiles were studied in phosphate buffer solution. Results: It was observed that the growth inhibition zone increased through clindamycin release due to the increasing CuO percentage in the nanocomposite of bioactive glass. The bioactivity of the nanocomposite/bioglass with CuO was superior to that of bioglass alone. In this study, the BG/20CuO sample showed a sustained release of clindamycin, which is sufficient for a drug delivery system. Conclusions: Increasing the Cu nanoparticles in bioactive glass samples leads to the release of Cu 2+ , which has a positive effect on the antibacterial mechanism, as well as decreasing the cultured Staphylococcus colonies found on the bioglasses. Therefore, it seems that the nanocomposite/bioglass of CuO is a promising option for aerobic bacterial inhibitor systems in common bone implant infections.

“…This study revealed a higher swelling capacity and controlled delivery of drug by oxidized starch/CuO nanocomposites than pure oxidized starch [148]. Dedhila Devadathan et al compared antifungal activities of their synthesized polyindole based nickel-zinc oxide nanocomposite, nickel-zinc oxide, polyindole, nickel oxide and zinc oxide and observed that polyindole based nickel-zinc oxide nanocomposites showed antifungal activity of 1cm, nickel-zinc oxide showed antifungal activity of 0.7cm and polyindole, nickel oxide and zinc oxide showed no antifungal activity [149]. Faisal Mukhtar et al reported antibacterial properties against E. coli of synthesized binary NiO-Fe 2 O 3 and NiO-CdO nanocomposites and ternary NiO-Fe 2 O 3 -CdO nanocomposite.…”

In the field of nanotechnology and nanoscience, transition metal oxides based nanocomposites (TMONCs) are promising for various application uses such as Supercapacitors, Sensors, Bactericidal properties, Photocatalytic Degradation, Solar Cells etc. Modification of transition metal oxide nanoparticles (TMONPs) to TMONCs by doping/mixing of another transition metal and metal oxide, carbon based nanoparticles, conducting polymers etc. to achieve enhanced surface area, increasing surface activities or number of active surface sites, reducing electron-hole recombination, increasing charge transfer processes etc. have been reported in literature. These improved properties are the possible reason for the enhancement in its practical applications efficiencies. This review summarizes recent development on transition metal oxides based nanocomposites for different potential applications. Also synthesis methods of transition metal oxide based nanocomposites have obtained an increasing attractions to achieve cost effectiveness and environment friendly routes of synthesis with high rate of production, high yield of product and also less toxic waste production. Transition metal oxides nanocomposites have been fabricated by various methods such as Microwave assisted synthesis technique, Sol-Gel method, Biosynthesis method, Co-precipitation process, Simple Chemical method etc. Different morphologies of transition metal oxides based nanocomposites have been summarized in this review article. Herein, this paper discuss about several reported synthesis techniques, various characterization techniques used for structural and surface properties identifications, different morphologies and various potential applications of transition metal oxide based nanocomposites.
