Compared with other sensors, the proposed sensor greatly enhanced the response signal of BPA due to the active surface area of N-G and high absorption efficiency of TA. Under the optimal conditions, the oxidation current increased linearly with increasing the concentration of BPA in the range of 0.05-13 µM with the detection limit of 4.0 nM. The fabricated electrode showed good reproducibility, stability and anti-interference. The developed electrochemical sensor was successfully applied to determine BPA in food package.","tracks":[{"project":"Allie","denotations":[{"id":"SS1_24720975_1_0","span":{"begin":206,"end":217},"obj":"expanded"},{"id":"SS2_24720975_1_0","span":{"begin":219,"end":222},"obj":"abbr"},{"id":"SS1_24720975_1_1","span":{"begin":241,"end":264},"obj":"expanded"},{"id":"SS2_24720975_1_1","span":{"begin":266,"end":269},"obj":"abbr"}],"relations":[{"id":"AE1_24720975_1_0","pred":"abbreviatedTo","subj":"SS1_24720975_1_0","obj":"SS2_24720975_1_0"},{"id":"AE1_24720975_1_1","pred":"abbreviatedTo","subj":"SS1_24720975_1_1","obj":"SS2_24720975_1_1"}],"attributes":[{"subj":"SS1_24720975_1_0","pred":"source","obj":"Allie"},{"subj":"SS2_24720975_1_0","pred":"source","obj":"Allie"},{"subj":"SS1_24720975_1_1","pred":"source","obj":"Allie"},{"subj":"SS2_24720975_1_1","pred":"source","obj":"Allie"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"Allie","color":"#ece893","default":true}]}]}}
