we say curcumin modified Ag nanoparticles and curcumin-Ag nanoconjugates. What is difference between them? nano conjugates contain nanocurcumin ?

The two terminology is confusing. Does in nanoconjugate curcumin is also nano sized and then used as reducing and capping agent to prduces Ag Nps? or it is same as curcumin...

In literature it is varyingly given the UV absorption peak of silver Nps. (416nm, 430nm, 490nm) which one is exact? does it depends on clour and size?

In literature varied uv absorption range of AG Nps formed are given and varied colour also. From yellow to green. But i am getting dark brown (BLACKISH) colour does this confirms the formation of...

For crosslinking it I am using NaOH but it degrades. How much pH should I maintain to avoid it's degradation?

Hii! I am working with guar gum, a natural galactomannan. For crosslinking it I am using NaOH but it degrades. How much pH should I maintain to avoid it's degradation?
