This can serve as a detection or monitor of therapeutic treatment of neurodegenerative disease, especially for Alzheimer's disease. It introduces methods of using carbazole-based fluorophores for labelling, imaging and detecting beta amyloid peptides, oligomers, and fibrils that fluoresce strongly u.....

一种防护口罩，该口罩由内至外包括如下功能结构层：水分单向传输层，保证该液体只能从内表面传送出去以保持皮肤干燥和舒适，防止被感染的液体传到皮肤、口、鼻；网状结构层，实现过滤功能；防水透气层，具有保护壳的功能以防止被带有细菌和／或病毒的飞沫吸收和穿透。该三层中所用的纤维最好都用多功能的抗菌剂处理过。所以本实用新型的口罩和不但穿戴舒适而且不论细菌／病毒是由外向内，还是由内向外地传播，都会被所接触到的各层纤维／织物杀死／抑制。因此可以有效地取代现有的各种保护口罩。

希望有一种能针对一组不同的β－内酰胺类抗生素筛选细菌以鉴定β－内酰胺酶的工具。一种将指示分子导入β－内酰胺酶而形成的生物传感器可达到该目的，但要求导入的指示分子基本上不会削弱蛋白质结合的亲和力，以保证较高的灵敏度。本发明研发了一种经修饰的β－内酰胺酶，该β－内酰胺酶的Ω环上或Ω环的外侧但接近其活性部位的残基被活性残基置换。
