Optical tweezers can catch dozens of transparent nano - particles , but the resolution limit of optical microscopy and be observed 光镊可以捕获几十纳米透明粒子,但受光学显微镜分辨的极限而无法观察。
Optical tweezers use the tiny force of a beam of light from a laser to push around and control tiny objects , from cells to plastic beads 光镊用这一来自激光光束的微力来推动和控制微小物体(从细胞到塑胶珠) 。
In applications of optical tweezers , red blood cells , yeasts , coliforms , phagocytes , chloroplast , etc . were successfully manipulated 另一方面,对于光镊技术在生物学中的应用我们也进行了较深入的研究。
Downhill , in the wake , came constance in her grey dress , watching the chair jolt downwards . they passed the narrow track to the hut 康妮穿着灰色的衣裳,在后面跟着轮痕,一边走着,一边望着颠镊着下坡的小车儿。
