Biogenic Synthesis of Metal Oxide Nanoparticles

Check if the same lab product or an alternative is used in the 5 most similar protocols

Zinc oxide, magnesium oxide, and manganese dioxide were purchased from Sigma-Aldrich (>99% purity). The metal oxides NPs were synthesized with slight modifications according to Rajabairavi et al. (2017) (link). Briefly, 100 ml of 5 × 10⁸ CFU/ml of the cell-free supernatant of P. polymyxa strain Sx3 (Figure 1B) gotten through double filter by using 0.22 μm millipore filter and 100 ml each of ZnO, MgO, and MnO₂ (1 mM) were mixed in their respective flasks. The flask containing the mixture was placed on the magnetic stirrer at room temperature for 24 h. The synthesized ZnO, MnO₂, and MgO nanoparticles were purified by centrifuging at 10,000 g for 20 min, followed by repetitive centrifugation after resuspending the pellets in double-distilled water. The collected pellets were freeze-dried using Alpha 1–2 LDplus (Model number: 101521, Fisher scientific, United States) and used for further characterization.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
