In this work, aminophenylboronic acid-functionalized magnetic nanoparticles were synthesized, and applied to selective separation of glycopeptides and glycoproteins.
Radix isatidis (R. isatidis) (Banlangen) is a traditional Chinese medicine (TCM) famous for its broad antiviral activity. Its clinical medical history spans several thousands of years in China. Many scientists and scholars have conducted systematic research on this herb from its pharmacognosy to pharmaceuticals, especially in China. Through our research and literature reports, we inferred that the antiviral activity of R. isatidis mostly depended on the water-soluble part, including amino acids, IRPS, nucleosides, and sulfur-containing alkaloids. By playing a role in directly killing pathogenic viruses or regulating the immune system to enhance anti-virus ability, R. isatidis's biological activities mostly depend on the synergistic effect of its multiple components. This article aims to expand understanding of R. isatidis in the following aspects including medicinal resources, chemical constituents, pharmacological activities, clinical applications, and separation and analytical technologies.
Mercury (Hg 2+ ), even ultra-low-concentration amount in water, presents a serious environment concern. Thus, the removal, especially Hg (II) content in the ultratrace level (ppb), from water is still challenging. In this work, without any pretreatment, one novel MOF material can act as high-capacity and collectable adsorbent for the removal of Hg (II) from water, especially for ultratrace Hg 2+ ion in the ppb magnitude, mainly due to a combined effect from the pore walls functionalized by free-standing, accessible acylamide and hydroxyl units.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
