USEOFTHELIGHTMICROSCOPE
USE OF THE LIGHT MICROSCOPEEach time the microscope is to be used it should be set up correctly to give a good image. Most often users forget to adjust the iris diaphragm and focus the condenser to give its optimum performance, this could result in objects in the preparation being undetected.There are many microscope set up procedures for specific functionality but the most versatile for general use is ‘Critical Illu......阅读全文

Oncotarget:首次利用光遗传学控制肿瘤发生
在一项新的研究中,来自美国塔夫斯大学的研究人员基于青蛙模型首次证实利用光控制细胞之间的电信号,阻止肿瘤形成,以及在肿瘤形成后,让它们正常化。这项研究是首次报道利用光遗传学特异性地操纵生物电信号从而阻止癌基因诱导的肿瘤形成,和导致癌基因诱导的肿瘤消退。相关研究结果于2016年3月16日在线发表在O

什么是暗视野显微镜
暗视野显微镜(dark field microscope)是光学显微镜的一种,也叫超显微镜(ultramicroscope )。暗视野显微镜(dark field microscope)的聚光镜中央有挡光片,使照明光线不直接进入物镜,只允许被标本反射和衍射的光线进入物镜,因而视野的背景是黑的,物
