Function/role of Sod-Acetate in the synthesis of Nanoparticles like Fe2O3.?
Only it control the pH or also act as binder of some other fucntional group with the Magnet (Fe2O3 orFe3O4)?
Dear Hafiz Muhammad Adeel Sharif :
Sodium acetate is hydrolyzed. pH increases.
СH3COO- + H2O = CH3COOH + OH-
The hydroxyl groups react with the ferric ions. Iron hydroxide precipitate
Fe3+ +3OH- = Fe(OH)3
and is decomposed into an oxide and water
2 Fe(OH)3 = Fe2O3 (nanoparticle) + 3H2O
Sodium acetate - pH regulator, a provider of ions to stabilize the nanoparticles in the dispersion.
Best regards
Instead of checking only the mRNA level, I want to check the active protein level of MMP-1 in Liver tissue from mice. How can I do that?
