摘要：生物组织光学透明技术是一种新兴的实验室制备技术，可以用于生物学和医学研究。这项技术通过使用聚合物和其他材料将生物样品固定在薄膜上，使样品变得透明，可以用来分析样品中的单个成分。透明化的样品可以使用不同的光学成像技术进行分子、细胞或原子水平的详尽观察。此外，此技术也可以应用于光敏性荧光标记、体内功能性测试、小鼠临床试验中的多功能体内显微成像方法、神经影像学方法、3D 扫描成像方法等。 Introduction: Biological tissue optical transparency technology is an emerging laboratory preparation technique that can be used for biological and medical research. This technology uses polymers and other materials to fix the biological sample on a film, making the sample transparent, which can be used to analyze the individual components in the sample. The transparentized samples can be observed in detail at molecular, cellular or atomic level using different optical imaging techniques. In addition, this technique can also be applied to photoreactive fluorescent labeling, in vivo functional testing, multi-functional in vivo microscopic imaging methods in mouse clinical trials, neuroimaging methods, 3D scanning imaging methods and so on. The transparency of biological tissue is realized by using a variety of materials such as polymers and waxes to immobilize the sample on a thin film. The most commonly used polymer is polyvinyl alcohol (PVA), which has good water solubility and low toxicity. After being treated with PVA solution or other materials for fixation or dehydration treatment, the specimen will become transparent without affecting its structure or composition. This method has been successfully applied to various tissues such as brain slices from mice and rats as well as human organs such as liver slices from humans. In addition to providing high resolution images of tissues at different scales ranging from single molecules to entire organs, this technology also allows researchers to study dynamic processes within tissues by combining it with other advanced microscopy techniques such as time-lapse imaging or fluorescence correlation spectroscopy (FCS). Furthermore, this technique has been widely used for drug screening applications due to its ability to provide real-time information about drug effects on living cells without damaging them. Conclusion: Biological tissue optical transparency technology is an emerging laboratory preparation technique that enables researchers to observe detailed structures within tissues at various levels without damaging them. It provides researchers with high resolution images of tissues at different scales ranging from single molecules up to whole organs while also allowing dynamic processes within tissues to be studied through combining it with other advanced microscopy techniques such as time-lapse imaging or FCS. Furthermore it has great potential for drug screening applications due its ability provide real-time information about drug effects on living cells without damaging them
