用脉冲激光束照射浸没在蒸馏水中的厚度为1mm的金属靶板，制备了金和银纳米粒子胶体。通过透射电子显微镜TEM分析研究了金属纳米颗粒的尺寸和尺寸分布。纳米粒子的浓度也通过原子吸收光谱AAS测量表征。研究了金、银纳米粒子对血清中GOT、GPT酶活性的影响。金和银纳米颗粒对（GOT）和（GPT）活性表现出抑制作用，并且这些作用随着纳米颗粒浓度的增加而增加。
Gold and silver nanoparticles colloids were produced by irradiating a metallic target plates with a thickness of 1mm immersed in distilled water with a pulsed laser beam. The size and size distributions of the metals nanoparticles were examined by the transmission electron microscope TEM analysis. The nanoparticles concentrations were also characterized by atomic absorption spectroscopy AAS measurement. The effects of gold and silver nanoparticles were studied on the activities of GOT and GPT enzymes in the sera. Gold and silver nanoparticles demonstrated inhibitor effects on the (GOT) and (GPT) activities, and these effects increased with increasing the concentrations of the
