采用真空或还原气氛对氧化铟锡（ITO）纳米粒子进行退火处理，获得不同的表面结构，并研究其对细胞色素c（Cyt c）分子吸附特性和构象的影响。通过透射电子显微镜、X射线衍射和拉曼散射等手段对退火诱导的ITO纳米粒子的形貌或结构变化进行了表征。观察到半导体ITO纳米颗粒增强的Cyt c的拉曼散射，并且发现增强的效率密切依赖于控制Cyt c负载所需的缓冲阴离子的吸附量的表面结构。通过对剩余溶液的吸收光谱测量，发现在分子弹性碰撞的瞬间，Cyt c与ITO表面发生了直接的电子转移，而O-端表面和金属-端表面发生了反向的电子转移过程.
Indium-tin-oxide (ITO) nanoparticles were annealed in vacuum or reducing atmosphere to obtain different surface structures and investigate their influence on the adsorptive character and conformation of cytochrome c (Cyt c) molecule. Annealing-induced morphometric or structural changes of ITO nanoparticles were characterized by instruments of transmission electron microscopy, x-ray diffraction, and Raman scattering. Semiconductor ITO nanoparticle-enhanced Raman scattering of Cyt c was observed and the enhanced efficiency was found to closely depend on the surface structures which control the adsorbance of buffer anions needed for Cyt c loading. Direct electron transfer between Cyt c and ITO surface at the moment of molecular elastic collision was found and a reverse electron transfer process for O-terminated surface and metal-terminated surface was observed, according to absorption spectroscopic measurement on the residual solution.
