| Abstract: |
| The self-assembled monolayers（SAMs） of 4,4′-bis（methanethiol）biphenyl（MTP） and 6-thioctic acid（TA） were covalently combined on to a bare gold electrode to make self-assembled monolayers（TA+MTP/Au SAMs）.It was then dipped into gold nanoparticles solution for a certain time to prepare the AuNPs/MTP+TA/Au electrode.The electrochemical behaviors of the modified electrode were investigated by cyclic voltammetry and electrochemical impedance spectroscopy.The results showed that the acidity variation of the electrode surface had an important influence on the electron transfer.The preparation conditions,determination conditions and anti-interference ability of glucose sensor were discussed,which showed that it was necessary to further study the microstructure and microenvironment of the modified electrode. |
