This study presents the development of multifunctional starch-based biopolymer films reinforced with nitrogen-doped carbon quantum dots (N-CQDs), synthesized via a hydrothermal method, and exhibiting a high quantum yield (~70 %). N-CQDs were incorporated into the starch matrix at varying concentrations (0.1-1.

Overexpression of protein lysine methyltransferase G9a, which catalyzes mono- and di-methylation of histone H3K9 and non-histone proteins, is closely associated with poor prognosis and metastasis of various cancers. Here, we designed and synthesized a series of novel G9a inhibitors bearing 2-tetrahydroisoquinoline substituted quinazoline scaffold. Among them, compound 31 with 2-dioxole fused tetrahydroisoquinoline exhibited the most potent inhibitory effects against G9a with an IC value of 0.

Photocatalysis has emerged as a promising strategy to address water pollution caused by heavy metals and antibiotics. Zeolites exhibit significant potential in petrochemical catalysis; however, the development of zeolite-based photocatalysts remains a critical challenge for researchers. Herein, a novel Z-scheme heterojunction was designed and fabricated on the titanium-silicon zeolite TS-1 by modifying g-CN via a simple calcination process.

Aims: Cardiac tumors are aggressive and asymptomatic in early stages, causing late diagnosis and locoregional metastasis. Currently, the standard of care uses gadolinium-based contrast agents for MRI, and the associated hypersensitivity reactions are a significant concern, such as gadolinium deposition disease. In addition, the proximity of cardiac lesions closer to vital structures complicates surgical interventions.

The nanoscale environment within the void spaces of metal-organic frameworks (MOFs) can significantly influence the photoredox catalytic activity of encapsulated visible-light photoredox catalysts (PCs). To compare two isostructural PC@In-MOF systems, three cationic Ru(II) polypyridine complexes were successfully encapsulated within the mesoscale channels of the anionic framework of InTATB (HTATB = 4,4',4''--triazine-2,4,6-triyltribenzoic acid), which features a doubly interpenetrated framework structure. This encapsulation yielded three heterogenized visible-light PCs, RuL@InTATB, where L = 2,2'-bipyridine (bpy), 1,10-phenanthroline (phen), or 2,2'-bipyrazine (bpz).
