| Abstract: | A graphene oxide-peptide based fluorescence sensor has been developed for matrix metalloproteinase 2 (MMP2), and its applicability has been demonstrated by monitoring the concentration of MMP2 secreted by HeLa cells, revealing that HeLa cells with a density of 5.48 × 10(5) cells per mL can produce 22 nM in cell culture media in 24 h. |
