“…Especially the nonstoichiometric p-type CuO with a narrow band gap (about 1.7 eV) is easy to adsorb oxygen molecules forming oxygen vacancies, and then generate reactive oxygen species, thereby it is extensively used in various applications such as catalysis [14,15], gas sensors [16], biological applications [17] and solar energy transformation [18][19][20]. However, so far, the study of using copper oxide modified silver bromide has not been reported yet.…”

“…The results showed that the sample with CuO NPs presented higher antibacterial activity than the sample coated with CuS nanoparticles which showed no reduction in the viability of tested bacteria [50]. Devi et al studied the antimicrobial activity of bulk, as-prepared and annealed CuO NPs against E. coli , Proteus mirabilis , Klebsiella spp., and their effect was comparable with the antimicrobial activity of gentamycin on these strains [9,51]. …”

This study aims to provide an updated survey of the main synthesis methods of copper oxide (CuO) nanoparticles in order to obtain tailored nanosystems for various biomedical applications. The synthesis approach significantly impacts the properties of such nanoparticles and these properties in turn have a significant impact on their biomedical applications. Although not widely investigated as an efficient drug delivery system, CuO nanoparticles have great biological properties including effective antimicrobial action against a wide range of pathogens and also drug resistant bacteria. These properties have led to the development of various approaches with direct applications to the biomedical field, such as tailored surfaces with antimicrobial effect, wound dressings and modified textiles. It is also believed that these nanosystems could represent efficient alternatives in the development of smart systems utilized both for the detection of pathogens and for the treatment of infections.

“…However, synthesis of flow-like CuO nanosheet is still a challengeable project until now. In addition, the commonly used synthetic routes for CuO nano-and micro-structures are limited for large-scale application due to the disadvantages of high temperature required, long reaction times, costly equipment, or complex procedures [16][17][18][19][20].…”

Here we report a simple hydrothermal route for the preparation of CuO nano-flower which has been proved to exhibit good performances in gas-sensing. We concentrate on the microstructure and morphology of CuO by adjusting the reaction time length. Four different morphologies that formed a flower-like shape with a diameter of 1-3 lm were obtained. The CuO nanostructures were characterized in detail by means of X-ray diffraction and scanning electron microscopy and were apparently seen that they were composed of abundant aggregative nanobelts. The prepared CuO properties in gas-sensing were also measured in our experiments. In addition, a proper growth mechanism was proposed based on the results. Moreover, the CuO nano-flowers may resolve the difficulties in low-dimensional gas-sensing applications after more research having been conducted.
