穿孔电极对电化学发光强度的影响
摘要:
电化学发光(ECL)作为一种灵敏度高、选择性好的分析方法,越来越受到人们的关注。这种方法已用于多种无机物、有机物、生物大分子和生物活性物质的测定及多种抗原、抗体和半抗原的免疫分析等[1~4]。

Effects of Perforated Platinum Electrode on the Electrochemiluminescence Intensity
Abstract:
The relation of the electrochemiluminescence (ECL) intensity with the shape of perforated and imperforated platinum electrodes has been investigated.ICCD (Intensified charge-coupled device) was used to get the images of ECL of Ru(bpy)3Cl2·6H2O and tripropylamine (TPA) on the electrodes.The results showed that the ECL was concentrated on the edge of the electrode.For the perforated platinum electrode,the ECL intensity was found to be dependent both on the electrode edge and the edge of the holes on the disk electrode.The ECL intensity of Ru(bpy)3Cl2·6H2O measured on the four-hole disk electrode was double higher than that measured on the simple disk electrode and the detection limit was increased approximately by three orders of magnitude from 1 fmol/L to 1 amol/L.
