• in cellular internalization of ZnO nanoparticles has also been observed by Appierot et al. [6] in a study of their antibacterial effect on E. coli and S. aureus. This work reports on an antimicrobial paper containing zinc oxide (ZnO) nanorods grown by a hydrothermal process, and which can be used for

• tissue papers. Conclusion Antimicrobial paper has been successfully prepared by growing ZnO nanorods on paper prepared from bleached soft wood kraft pulp by using a simple hydrothermal process at low temperature. The antimicrobial paper inhibits the growth of harmful microbes due to a slow release of

• magnetic stirring of the mixture of the three components at room temperature. The precursor solution was then transferred to a Teflon-lined stainless steel autoclave (45 mL volume, Parr Instrument Co.) for the hydrothermal reaction. The hydrothermal process was carried out at 200 °C for 24 h in an electric

• hexamethylenetetramine (C6H12N4, Aldrich) were used as starting materials for the growth of the ZnO nanorods. A low-temperature hydrothermal process was used for the ZnO-nanorod growth. Detailed processes for the hydrothermal growth of the single crystalline ZnO nanorods are described in our previous reports [9][37][38

• -shaped ZnO structure is very sensitive to the growth conditions and it appears to be difficult to get reproducible results. It was also reported that ZnO nanotube arrays were grown on zinc foils via a hydrothermal process, attributed to the gradient in the concentrations of zinc precursors from Zn foil

• demonstrating a single crystalline structure. The width, length and density of the nanorods on the substrates are dependent on the synthesis conditions, such as, seeding of the substrates, concentration of precursors in the growth solution, as well as the duration of hydrothermal process [27][28][29].
