Image Guided Surgery

Navigating Through the Brain

One of the challenges of neurosurgery is orientation at the surgical site. When resecting tumors, removing arteriovenous malformations, or clipping aneurysms, surgeons often have to work near healthy…

[Translate to chinese:] Left: Tissue cells marked with an immunolabel (FITC) illuminated with wide-band UV excitation. Note the tissue structure with blue autofluorescence. Right: Same tissue and same immunostaining with FITC label illuminated with epi-illumination using narrow-band blue (490 nm) light. Note the increased image contrast (Ploem, 1967)

Milestones in Incident Light Fluorescence Microscopy

Since the middle of the last century, fluorescence microscopy developed into a bio scientific tool with one of the biggest impacts on our understanding of life. Watching cells and proteins with the…

Chronic Inflammation Under the Microscope

In the course of chronic inflammation certain body areas are recurrently inflamed. This goes along with many human diseases. With the help of widefield light microscopy, the underlying processes can…

什么是OCT？

光学相干断层扫描（OCT）是一种无创、非接触式成像方式，可用于显示并监测生物组织的形态变化。OCT利用低相干干涉原理，可生成横断面视图，以揭示感兴趣组织的亚表面细节。在大部分常见眼科应用中，OCT系统通过近红外光生成角膜、虹膜、晶状体、玻璃体和视网膜等组织微结构的高分辨率体积图像。这些图像可加强对病理状况的理解，例如青光眼、老年性黄斑变性或糖尿病视网膜病变。

选择学生显微镜需要考虑的因素

对于教师来说，选择教育显微镜并非易事。显微镜必须经得起并非总是小心翼翼的双手的日常使用，必须能够持续运行，还必须符合预算要求。尤其是学生用显微镜，实用性方面起着重要作用：尺寸、重量、布线和设计在日常使用中非常重要，甚至在决定使用显微镜的设备和附件之前就应考虑到这一点。如果选择得当，教育显微镜将为大中小学的年轻人打开一扇通往微小细节的宇宙之窗，让他们对科学产生足够的兴趣，并将其作为自己的职业。

Gene Editing with CRISPR/Cas9 - Breakthrough in Genome Engineering

The CRISPR/Cas9 system is one of several different bacterial systems for defense against viral attacks. It consists of two main components. One is a small piece of RNA which binds to the viral target…

纸张样品 - SEM样本制备

徕卡EM RES102的使用说明 - 为了测试该程序的适用性，已用离子束截面切割法制备了一个涂布纸样。利用离子束截面切割法，可制备纸张横截面。在该样品处理的基础上，可在扫描电子显微镜下显示热敏纸基本未受影响的原始结构。
