General description
荧光素（游离酸 CI 45350）是一种呫吨染料。荧光素（游离酸）分子可分为两部分。一部分含有呫吨基团，其可充当荧光团，而另一部分带有苯基团，其是荧光控制基团。
Application
荧光素（游离酸）已用作视网膜成像中的染色剂。
荧光素（游离酸）被广泛用作许多活细胞和组织的荧光染色和跟踪。它也适合作为研究胆管运动的标志物。临床应用包括评估眼表和描绘缺乏血脑屏障的脑区域，以实现准确的恶性胶质瘤手术切除。荧光素血管造影有助于研究视网膜血液供应的变化。荧光素还可以作为一种生理示踪剂来表征鲑鱼的肠通透性（Schep 等，1998），并用于房水流量的荧光光度法测量。它被广泛用作量子产量标准。

Acrylic bone cement (ABC) has been used as a grouting agent in joint replacement surgery for over 50 years. In particular, ABC is irreplaceable for high-load joint replacement such as total hip joint replacements (THJRs) and total knee joint replacements because

Rational design strategies based on practical fluorescence modulation mechanisms would enable us to rapidly develop novel fluorescence probes for target molecules. Here, we present a practical and general principle for modulating the fluorescence properties of fluorescein. We hypothesized that (a)
