However, precise control of hot carrier behaviors and catalytic reactions driven by them on the subnanometer scale remains challenging. Herein, the transportation of plasmonic hot carriers in two-dimensional (2D) van der Waals (vdW) heterojunctions consisting of graphene and MoS<sub>2</sub>, as well as its influence on photocatalytic reactions, has been in situ monitored by surface-enhanced Raman spectroscopy (SERS) with atomic layer accuracy. Direct spectral results prove that when the MoS<sub>2</sub> layer gradually moves closer to the top Au nanoparticles (NPs), the reduction reaction efficiency induced by hot electrons improves, while the oxidation process induced by hot holes is inhibited and vice versa. This originates from the redistribution of electromagnetic fields in the plasmonic nanogap as well as the change in the hot carrier generation and transfer efficiency with different MoS<sub>2</sub>/graphene vdW heterojunction stacking modes, as revealed by time-resolved transient absorption spectra (TAS), electromagnetic field simulations, and density functional theory (DFT).

Compared with other solvents, these cyclodipeptides exhibit ultrahigh sensitivity to dimethyl sulfoxide (DMSO), which induces a conformational transition from parallel to perpendicular dimerization. It leads to a reversed screw sense of the chromophores, facilitating tunable chiroptical properties. In a mixed DMSO/water system, the folded cyclodipeptides perform as efficient molecular clamps that recognize VK1 through charge-transfer complexation. Additionally, d,d- and l,l-configured cyclodipeptides displayed enantioselective recognition of VK1, as evidenced by differences in binding affinity, circularly polarized luminescence and self-assembled nanoarchitectures.

While 5mC does not block DNA replication and is not mutagenic, the biological consequences of 5mC affecting the flanking guanine with a bulky modification during DNA replication are not well understood. This paper examined the lesion bypass and mutagenicity of the 2-acetylaminofluorene-modified guanine DNA adduct (dG-AAF) in epigenetically relevant sequence contexts in <i>Escherichia coli</i>. The C/5mC context exhibited significantly different bypass and mutagenicity profiles for dG-AAF. The biological outcomes also varied depending on the nature of the 3' flanking base and the lesion bulkiness. In addition, we extensively observed a unique type of -1 G deletion when the lesion was flanked by 3' purines, possibly due to the formation of a stacked slipped mutagenic intermediate. However, there was no such deletion with 3' pyrimidines. Our findings provide a new perspective on the role of epigenetic markers in DNA replication and could help to develop methods to identify mutation patterns associated with specific mutational signatures or spectra in cancer.</p>","PeriodicalId":31,"journal":{"name":"Chemical Research in Toxicology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144558425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
