摘要：
An electrochemical immunosensor based on nano-size particulate gold (nano-Au) monolayer as sensing interface has been developed for probing complement III (C3). The thiol functional group-derived carbon ceramic electrode (CCE) was firstly constructed using (3-mercaptopropyl) trimethoxy silane (MPTMOS) as sol-gel monomer. The stable nano-Au monolayer was obtained resulting from covalent combination between nano-Au and thiol group on the surface of CCE. The nano-Au monolayer formed was utilized as a sensing platform for the immobilization of C3 a...
