应用

6-氨基荧光素已被证明是基于富勒烯的脂质体纳米结构（称为'buckysomes'）的有效荧光标记试剂。溶解在0.1N NaOH中的6-氨基荧光素可通过490nm处的最大吸光度进行定量。溶解在6N HCl中的脱羧化的6-氨基荧光素（通过在110℃恒沸24小时制备）可通过454nm处的最大吸光度进行定量。醛基是通过对蛋白质的氧化损伤形成的，其可以通过与脱羧的6-氨基荧光素结合来检测。

其他说明

注意：不要与荧光胺混淆。

A method for covalent attachment of a fluorescent molecule to the carbohydrate moieties of glycoproteins is described. The glycoproteins were oxidized with periodate under mild conditions selective for sialic acid (Van Lenten, L. and Ashwell, G. (1971) J. Biol. Chem.

Oxidative modification of proteins is implicated in a number of physiologic and pathologic processes. Metal-catalyzed oxidative modification usually causes inactivation of enzymes and the appearance of carbonyl groups in amino acid side chains of the protein. We describe use of

Polyelectrolyte microcapsules represent versatile stimuli-responsive structures that enable the encapsulation, protection, and release of active agents. Their conventional preparation methods, however, tend to be time-consuming, yield low encapsulation efficiency, and seldom allow for the dual incorporation of hydrophilic and hydrophobic

Although computer simulation and cell culture experiments have shown that elongated spherical particles can be taken up into cells more efficiently than spherical particles, experimental investigation on effects of these different shapes over the particle-membrane association has never been reported.

Patchy particles are next generation colloidal building blocks for self-assembly and find further use as (bio) sensors. Progress in this direction crucially depends on developing straightforward preparation pathways able to provide patchy particles with highest uniformity and integrating precise, orthogonal
