The grafting of a monolayer of 6 nm superparamagnetic cyanide-bridged CsNiCr nanoparticles was achieved on a Ni(II)-functionalized Si(100) substrate; magnetic studies reveals that the grafted nanoparticles are nearly magnetically isolated within the monolayer.

Herein, we present an efficient approach for developing electrochemical aptasensing interfaces, by "click" postfunctionalization of phenylethynyl-grafted glassy carbon substrates with mixed monolayers containing biorecognition elements and phosphorylcholine zwitterionic groups. Typically, controlling the composition of multicomponent surface layers by grafting from a mixture of aryldiazonium salts is challenging due to differences in their chemical reactivity. Our approach circumvents this issue by employing the electrochemical reduction of a single aryldiazonium salt containing a silyl-protected alkyne group followed by deprotection, to create phenylethynyl monolayers which can subsequently accommodate the concurrent immobilization of bioreceptors and zwitterionic groups through "click" postfunctionalization.

Scaffold-free tissue engineering strategies using cellular aggregates, microtissues, or organoids as "biological building blocks" could potentially be used for the engineering of scaled-up articular cartilage or endochondral bone-forming grafts. Such approaches require large numbers of cells; however, little is known about how different chondrogenic growth factor stimulation regimes during cellular expansion and differentiation influence the capacity of cellular aggregates or microtissues to fuse and generate hyaline cartilage. In this study, human bone marrow mesenchymal stem/stromal cells (MSCs) were additionally stimulated with bone morphogenetic protein 2 (BMP-2) and/or transforming growth factor (TGF)-β1 during both monolayer expansion and subsequent chondrogenic differentiation in a microtissue format.

Objective: Donor liver preservation methods and solutions have evolved over the last years. Liver sinusoidal endothelial cell (LSEC) barrier function and integrity during preservation is crucial for outcomes of liver transplantation. Therefore, the present study aimed to determine optimal preservation of LSEC barrier function and integrity, using different preservation solutions.

Improving the adsorption capacity of materials for pollutants by means of modification is an important direction in the research of water treatment technology. To improve the applicability of sodium alginate composites in the field of adsorption, magnetic sodium alginate-based hydrogel microsphere adsorbent material FeO@SA/PEI-Fe (FSPF) was synthesized in a single step by using polyethyleneimine grafting modification of sodium alginate by sol-gel method. The material was used for the removal of direct blue GL (DB 200) and direct date red B (DR 13) from simulated wastewater, as well as Cu(II) and Pb(II) from simulated wastewater with heavy metal ions.

Heavy metal ions, are non-biodegradable, high toxic tendency, and have serious hazardous effects on the health of humans. Then, removing them from the environment using different techniques is necessary. Several routes are expensive, low-efficient, and require a long time to achieve adsorption equilibrium.
