Second Harmonic Generation (SHG) microscopy dates back to 1974, but effective biological use of the technique has a history of barely 10 years. It is now widely used to image collagen in many different applications, and is becoming useful for imaging myosin and some polysaccharides. A separate line on research has focussed on SHG dyes, which can provide high-speed indication of membrane potential and are now in use in neurobiology. This review looks at the progress to date in these different fields.
二次谐波产生(SHG)显微镜技术可追溯到1974年,但该技术在生物学上的有效应用历史却只有短短10年。如今,它在许多不同的应用中被广泛用于对胶原蛋白进行成像,并且在对肌球蛋白和一些多糖进行成像方面也变得越来越有用。另一项研究方向聚焦于SHG染料,其可提供膜电位的高速指示,目前已在神经生物学中得到应用。本文综述了这些不同领域迄今为止取得的进展。
