用伏安法研究了血红蛋白（Hb）分子在氧化铟锡（ITO）裸电极上的直接电化学行为。一对氧化还原峰电流，这是由于血红素Fe（III）/Fe（II）对血红蛋白分子，被发现在血红蛋白吸附的ITO电极在磷酸盐缓冲盐水（PBS; pH 7.4）的解决方案。利用衰减全反射（ATR）技术中的平板光波导（SOWG）光谱技术，研究了血红蛋白（Hb）分子吸附在ITO电极表面的Soret带。所得的光谱表明，直接吸附的血红蛋白分子没有显着变性的裸ITO电极表面上。
The direct electrochemistry of hemoglobin (Hb) molecules adsorbed on bare indium tin oxide (ITO) electrodes was investigated by voltammetric methods. A pair of redox peak currents, which is attributed to a heme Fe(III)/Fe(II) couple in Hb molecules, was found at Hb-adsorbed ITO electrodes in phosphate-buffered saline (PBS; pH 7.4) solutions. Slab optical waveguide (SOWG) spectroscopy, which is one of the attenuated total reflection (ATR) techniques, was employed to observe the Soret band of Hb molecules adsorbed on the bare ITO electrode surfaces. The obtained spectra indicated that directly adsorbed Hb molecules were not significantly denatured on the bare ITO electrode surfaces.
