Here, we present the fabrication of a bioprinted hepatic construct using a composite bioink composed of in-house synthesized gelatin methacryloyl (GelMA), rat liver-derived decellularized extracellular matrix (dECM), and HepG2 cells. GelMA imparted mechanical integrity and biocompatibility, while the liver-specific dECM provided bioactive cues critical for recapitulating the hepatic microenvironment. Constructs were crosslinked using microbial transglutaminase and a photoinitiator to ensure structural stability and shape fidelity. Functional characterization included cytocompatibility assays (MTT, live/dead), metabolic activity assays (albumin and urea secretion), and liver-specific enzyme analysis (LDH, ALT, and ALP), alongside gene expression profiling, all of which confirmed hepatic function within the constructs. This synergy enhances cellular functionality and supports accurate fibrosis modeling for translational research. To establish a fibrosis model, methotrexate (MTX) was introduced, resulting in functional decline and upregulation of fibrosis-associated genes, thereby validating the fibrotic phenotype.

In MoS<small><sub>2</sub></small>/hBN, a broad UV band near 350 nm also appears under 200 nm excitation and is attributed to impurity-related defect luminescence in hBN. The interfacial processes are governed by temperature-sensitive radiative channels involving defect-bound states or localized excitons in MoS<small><sub>2</sub></small>. Our results highlight the crucial role of interlayer coupling and spectral sensitization in enabling new radiative pathways in 2D heterostructures, offering novel strategies for tailoring light emission in layered optoelectronic systems.</p>","PeriodicalId":102,"journal":{"name":"RSC Advances","volume":" 44","pages":" 37183-37193"},"PeriodicalIF":4.6,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12498572/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145243259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
