What was studied?
Researchers characterized laccase-like reactions and developed solution and portable sensing formats for selected phenolic compounds.
What did the researchers report?
GHK-Cu supported measurable color responses, including assays tested in different water matrices and a cotton-based sensor format.
What are the limits?
Detection limits depend on substrate, medium and sensor design. Catalytic activity in a chemical assay is not evidence for a cosmetic or medical outcome.
