A novel and facile dynamic interfacial adhesion (DIA) strategy has been successfully applied in the reversible fabrication of complex 3D hydrogel constructs based on dynamic covalent bonds (DCBs). By tailoring the geometry of gel building blocks (GBBs) and incorporating stimuli-responsive units, various shapes could be easily achieved.

The incorporation of a selenoimidazolium-based chalcogen bond (ChB) donor into a bis-heteroleptic Ru(II) complex (Ru-Se) has been designed for the first time to explore its anion-sensing properties and understand its selectivity to specific classes of anions. Photophysical studies demonstrate the receptor's selectivity toward phosphates, while H NMR displays its ability to recognize both I and HPO among the different halides and oxoanions through ChB interaction in CHCN and dimethyl sulfoxide- solvents, respectively. Additionally, microscopic studies such as DLS and TEM reveal that the selective turn-on sensing of HPO and HPO compared to I is driven by supramolecular aggregation behavior.

Omniphobic surfaces, which repel virtually any liquid regardless of its wettability, have been developed using doubly re-entrant microstructures. Although various microfabrication techniques have been explored, these often require multiple complex steps. In this study, reaction-diffusion photolithography (RDP) is used to fabricate micropost arrays with doubly re-entrant geometries through a single-step ultraviolet (UV) exposure process.

The present work reports the synthesis, characterization, and excited state photo-physical studies of two copper(II) compounds, 1 & 2, which show interference-free emission with homocysteine (Hcy). Cu(II) complexes offer an orthogonal detection strategy involving fluorescence and electrochemical methods, paving the way for improved point-of-care diagnostics and early cardiovascular diseases intervention. The reduction-induced emission enhancement (RIEE) of Cu complexes facilitates the fluorescence measurement of Hcy at physiological pH.

Monomer compounds from natural products are the major source of active pharmaceutical molecules, which provide great opportunities for discovering of new drugs. However, natural products contain a large number of rather complex compounds. It is difficult to obtain high-purity monomer compounds from complex natural products.

Antimicrobial resistance and impaired bone regeneration are the great challenges in treating infected bone defects. Its recurrent and resistant nature, high incidence rate, long-term hospitalization, and high medical costs have driven the efforts of the scientific community to develop new therapies to improve the situation. Considering the complex microenvironment and persistent mechanisms mediated by resistant bacteria, it is crucial to develop an implant with enhanced osseointegration and sustained and effective infection clearance effects.
