Highlights: [•] We have demonstrated a colorimetric probe for pH-sensitive based on PGA-AuNPs system. [•] The assays could be achieved with the naked eye. [•] The colorimetric probe showed a sensitive response to pH variation between 1 and 9. [•] The aggregation of AuNPs corresponded to the secondary structure of PGA. [ABSTRACT FROM AUTHOR]
