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