Can the surface modification and/or morphology affect the ecotoxicity of zinc oxide nanomaterials?

Photo-regulated dual-functional zinc oxide nanocomposite for synergistic sterilization and antioxidant treatment

“…The Tauc relationship utilized was as follows: αhν = A ( hν − E g ) n /2 where α refers to the absorption coefficient, A is a constant, h represents Planck's constant, ν denotes the photon frequency, E g is the optical band-gap, and where for direct bandgap semiconductors, n is 1. 37 Based on the absorption spectrum obtained, the calculated bandgaps of FZnO, C-FZnO and C-FZnO-RT were 3.14, 3.18 and 1.44 eV, respectively. These results demonstrated that the three materials exhibited strong light absorption in both the UV and visible regions.…”

“…Nanomaterials (NMs) less than 100 nm in size provide a greater surface volume, enhancing their intrinsic physicochemical properties and increasing their susceptibility to external influences when compared to the bulk material. Depending on NM composition, morphology, and size, these compounds may be used in very specialized applications, such as in special nanostructures made from iron or transition metals whose magnetic properties can be used for biosensing [30] , [38] , [39] , [40] .…”

Rationale and decision rules behind the ECETOC NanoApp to support registration of sets of similar nanoforms within REACH

“…Evidence on the role of shape on oral and dermal routes of exposure is much more limited. Also, in the case of environmental fate and ecotoxicity, the role of shape does not seem to be as marked as it is for inhalation toxicity (Dai et al 2015;Wray and Klaine 2015;Zhang, Xiao, and Fang 2018;Melegari et al 2019).…”
