The precise localization and controlled chemical treatment of structures on a surface are significant challenges for common laboratory technologies. Herein, we introduce a microfluidic-based technology, employing a double-layer microfluidic device, which can trap and localize in situ and ex situ synthesized structures on microfluidic channel surfaces. Crucially, we show how such a device can be used to conduct controlled chemical reactions onto on-chip trapped structures and we demonstrate how the synthetic pathway of a crystalline molecular material and its positioning inside a microfluidic channel can be precisely modified with this technology. This approach provides new opportunities for the controlled assembly of structures on surface and for their subsequent treatment.

Efficient delivery of sensitive nucleic acid payloads, including mRNA, in remains challenging, especially with traditional, labor-intensive transgenesis methods. We addressed these challenges using polymeric nanogels (NGs) as an advanced platform for mRNA delivery in . These polymeric delivery vehicles can be engineered to suit desired applications owing to their chemical versatility, resulting from the ability to conjugate multiple functional groups onto the same backbone.

Porous CuNi films are promising candidates for electrocatalytic water splitting, with their catalytic performance largely influenced by the crystallographic structure and chemical state. In this study, by employing a magnetic field-controlled bubble template-assisted electrodeposition method, CuNi films with a preferred Ni(111) crystal orientation were synthesized. Moreover, adjusting the magnetic field direction during deposition can affect the degree of preferred orientation and, consequently, the electrochemical activity of the films.

Introduction: Opioid-induced constipation (OIC) affects up to 90% of patients with cancer receiving long-term opioid-related analgesic therapy, resulting in various potential complications, compromised pain management and decreased quality of life. Laxatives stimulate or facilitate bowel evacuation. Traditional laxatives, such as polyethylene glycol and lactulose, are widely used because of their low cost, easy accessibility and tolerability.

Synthetic dye production and the consequent generation of dye-rich wastewater are major concerns of water quality in many countries. We developed a sustainable approach with deep eutectic solvent (DES) treatment to enhance the efficiency of mixed cellulose ester (MCE) membrane-based dye removal material. The DES composition and treatment conditions were optimized, and the treated membranes were comprehensively characterized.

Two-component flavin-dependent monooxygenases are of great interest as biocatalysts for the production of pharmaceuticals and other relevant molecules, as they catalyze chemically important reactions such as hydroxylation, epoxidation and halogenation. The monooxygenase components require a separate flavin reductase, which provides the necessary reduced flavin cofactor. The tryptophan halogenase Thal from Streptomyces albogriseolus is a well-characterized two-component flavin-dependent halogenase.
