Fabrication of porous covalent organic frameworks as selective and advanced adsorbents for the on-line preconcentration of trace elements against the complex sample matrix.

Jing-Min Liu et al.

Journal of hazardous materials, 344, 220-229 (2017-10-19)

Herein, for the first time, the typical porous Covalent Organic Frameworks (COFs) CTpBD with superior chemical stability and large surface area were applied as sorbents for solid phase extraction of trace ions via flow injection followed by inductively coupled plasma

A new painkiller nanomedicine to bypass the blood-brain barrier and the use of morphine.

Jiao Feng et al.

Science advances, 5(2), eaau5148-eaau5148 (2019-02-23)

The clinical use of endogenous neuropeptides has historically been limited due to pharmacokinetic issues, including plasma stability and blood-brain barrier permeability. In this study, we show that the rapidly metabolized Leu-enkephalin (LENK) neuropeptide may become pharmacologically efficient owing to a
