Methylene blue research notes
What methylene blue is, how concentration and purity work, and what the published research actually says. Every note links to its sources.
Methylene blue: concentration, purity and batch testing
How to read concentration labels, distinguish purity from strength, and understand what a batch certificate measures.
Read the note →Why methylene blue changes colour: redox chemistry explained
From the blue bottle demonstration to reaction kinetics: how a visible colour change helps researchers follow electron transfer.
Read the note →Methylene blue and light: an introduction to photocatalysis
Light can change what a molecule does. Two studies explore methylene blue as a photocatalyst and explain why more dye is not always better.
