“…After particle precipitation, dumbbell-shaped ZnO NPs were generated with further heating at 100 °C for 4 h. In contrast to the dumbbell-shaped ZnO NPs, sphere-shaped ZnO NPs (12–46 nm) resulted from drying at 60 °C. The submicron ZnO dumbbell structure was generated using a chemical bath deposition technique at low temperature (80 °C) [ 51 ]. The resulting ZnO dumbbells were 1–2 μm long, 200–300 nm wide at one end, and 250–400 nm wide at the other end.…”

Zinc oxide (ZnO) nano/microparticles (NPs/MPs) have been studied as antibiotics to enhance antimicrobial activity against pathogenic bacteria and viruses with or without antibiotic resistance. They have unique physicochemical characteristics that can affect biological and toxicological responses in microorganisms. Metal ion release, particle adsorption, and reactive oxygen species generation are the main mechanisms underlying their antimicrobial action. In this review, we describe the physicochemical characteristics of ZnO NPs/MPs related to biological and toxicological effects and discuss the recent findings of the antimicrobial activity of ZnO NPs/MPs and their combinations with other materials against pathogenic microorganisms. Current biomedical applications of ZnO NPs/MPs and combinations with other materials are also presented. This review will provide the better understanding of ZnO NPs/MPs as antibiotic alternatives and aid in further development of antibiotic agents for industrial and clinical applications.

“…37,38 ZnO nanostructures from pure to hybrid structures have been developed as SERS substrates due to their non-toxicity and biocompatibility. 10,15,16 In order to meet the demands of their applications, a wide range of morphologies of ZnO semiconductor nanostructures, including nanowire, 39,40 nanodome, 10 nanoplate, 41 nanorod, 42,43 nanoparticle, 25,44 dumbbell, 45 nanotube, 46,47 and hexagon, 30 have been developed. Semiconductor-based SERS substrates are generally less efficient than noble metal substrates.…”

“…Due to adsorption of a growth unit on its polar and non-polar faces, the crystal starts growing longer and larger. The growth mechanism responsible to produce ZnO rod type structures has been already discussed with details somewhere else [35]. From figures 4(a)-(h) it is clear that CS is observed to be responsible in producing the multipod shaped Z-CS composite.…”

“…Presence of -OH and C=O groups on the surface of CS make it hydrophilic in nature [38]. Herewith we propose that Zn 2+ produced during synthesis of ZnO using an aqueous solution of Zn(CH 3 COO) 2 can get coupled with such active sites especially where -OH group is present due to the electrostatic interactions [32,35,[39][40][41]. The Zn 2+ ions coupled at the surface of CS further reacts with the OH − ion present in the reaction solution to produce Zn(OH) 2 at the CS surface.…”

High yield, low cost, environmentally friendly chemical bath synthesis process is used to produce submicron structures of ZnO and ZnO-carbon composites. Synthesis of ZnO rod structures (submicron sized) were confirmed using SEM images. To synthesis ZnO-carbon composites, well characterized carbon spheres produced using aerosol assisted CVD technique was used. Use of carbon spheres as a seed during synthesis of ZnO is observed to produce multipod structures of ZnO on to the surface of carbon spheres; the growth is explained by proposing suitable model. Room temperature photoluminescence spectra recorded for ZnO and ZnO-carbon composites synthesized show a systematic disappearance of a band-edge emission (sharp peak present at ∼380 nm observed for pure ZnO) with increased number of carbon spheres. Competent photo-catalytic activity of synthesized composite is confirmed by studying photo degradation investigation performed using a model dye molecule i.e. methyl orange. The work reveals possibility to use synthesized composites as a nontoxic and biocompatible catalyst for fragmentation of a methyl orange dye molecule. Photo-degradation mechanism of a methyl orange dye is proposed herewith considering the role of carbon spheres and ZnO in presence of UV photon.
