摘要
In pH 5.5 phosphate buffer solution, N-n-undecyl-N'-(sodium-p-amino-benzenesulfonate) thiourea (UPT) produced a pair of redox peaks on the bare glassy carbon electrode. At the multi-walled carbon nanotube (MWNT) modified electrode, the electrochemical behavior of UPT enhanced greatly. In the presence of bovine serum albumin (BSA), the peak currents of UPT decreased linearly due to the formation of a super-molecular complex. This method was successfully applied to the determination of BSA in a bovine serum sample.
