Biodegradability study and pH influence on growth and orientation of ZnO nanorods via aqueous solution process

► A simple two step method was adopted to fabricate vertical ZnO nanorod onto seedlayer glass and Si substrates. ► The optimum vertical ZnO rod growth occur within the pH range of 6-7. ► Biodegradability studies reveal that the grown ZnO rods are found to be dissolving in biofluids.
