“…The anti-radical activity of the Zn-Mn-Cu multioxide material could be compared with that of peroxidase, and that of the Mn-Cu multioxide material with that of bromelain. Compared to the homogeneous CuO and MnO oxides synthesised by Neethidevan et al (Neethidevan et al 2023), Zn-Mn-Cu multioxide and Mn-Cu multioxide show twice the activity against the radical. In addition, Zn-Mn-Cu multioxide shows similar activity to CuO in study of Rehana et al (Rehana et al 2017), and Mn-Cu multioxide twice this value.…”

The study analyses nanotechnology advances in the synthesis of catalytic nanozymes that mimic enzymatic properties, but are also inorganic nanomaterials. It compares Zn-Mn-Cu multioxide and Mn-Cu multioxide nanomaterials in the role of nanozymes and photocatalysts, in the decomposition of trypan blue dye. The study showed that Zn-Mn-Cu multioxide nanoxide has activity as a peroxidase-like nanozyme (100 mUnit/mL) and achieves 75% dye degradation as a photocatalyst under UV light. While Mn-Cu multioxide shows enhanced photocatalysis under visible light (45% degradation), consistent with its biocatalytic hydrolysis mechanism. In addition, both materials showed biocatalytic activity in the degradation of trypan blue dye (25%), without an additional light source. Further investigation of these dual nanozyme activities may reveal new solutions for their environmental use.

Nanozymes are nanoscale materials that exhibit enzymatic-like activity, combining the benefits of nanomaterials with biocatalytic effects. The addition of metals to nanomaterials can enhance their nanozyme activity by mimicking the active sites of enzymes, providing structural support and promoting redox activity. In this study, nanostructured oxide and silicate–phosphate nanomaterials with varying manganese and copper additions were characterized. The objective was to assess the influence of metal modifications (Mn and Cu) on the acquisition of the nanozymatic activity by selected nanomaterials. An increase in manganese content in each material enhanced proteolytic activity (from 20 to 40 mUnit/mg for BG-Mn), while higher copper addition in glassy materials increased activity by 40%. Glassy materials exhibited approximately twice the 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid radical activity (around 40 μmol/mL) compared to that of oxide materials. The proteolytic and antioxidant activities discussed in the study can be considered indicators for evaluating the enzymatic properties of the nanomaterials. Observations conducted on nanomaterials may aid in the development of materials with enhanced catalytic efficiency and a wide range of applications.
