However, the potential leakage of heavy metal ions such as Pb(II) and Sn(II) from PSCs poses significant environmental and health threats, yet the environment’s capacity to respond remains unknown. This work pioneeringly reports the environment’s natural remediation potential in addressing the risks of perovskite leakage. We find that environmental waste yeasts can efficiently capture leaked Pb(II) and Sn(II) through a combination of physical and chemical adsorption mechanisms. These perovskite heavy metals are further biotransformed and immobilized. Additionally, our study shows a higher removal rate for Sn ions, revealing enhanced environmental sustainability by applying lead-free perovskite photovoltaics. This work conveys a microbial cleanup strategy for removing perovskite heavy metals from the environment, contributing to the advancing practical implementation of perovskite photovoltaics.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":null,"pages":null},"PeriodicalIF":11.4,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142208518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, conventional PSs can cause unwanted side effects. Activatable photosensitizers (aPSs) offer a solution by remaining inactive until triggered within tumor microenvironment. Here, we present HFP-SS-Fc, a novel glutathione (GSH) aPS that leverages the high GSH concentration in tumors. HFP-SS-Fc exhibits potent near-infrared (NIR) fluorescence and a robust photodynamic effect upon exposure to tumor-specific GSH levels. A disulfide bond links ferrocene to HFP-SS-Fc, quenching NIR emission and hindering ROS generation. This ferrocene moiety also facilitates •OH production and O2 release through a Fenton-like reaction, maintaining efficacy in hypoxic tumors. Inspired by its theranostic potential in vitro, HFP-SS-Fc successfully achieves real-time tumor imaging and significant tumor growth inhibition in vivo. This study has presented HFP-SS-Fc as a promising tool for synergistic PDT and CDT with minimized side effects, guided by NIR fluorescence.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":null,"pages":null},"PeriodicalIF":11.4,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142208517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While ionic conductor-based sensors offer high stretchability (>100%), achieving both robustness and high conductivity is difficult. In this study, ultrastretchable, tough, and highly conductive nonvolatile polymer electrolytes, referred to as ionogels, were devised using a solvent-exchange method. Compared to other gel-type materials, such as organogels and hydrogels, the ionogels exhibit outstanding elasticity (>1000% strain at break), toughness (∼100 MJ m–3), and ionic conductivity of (∼20.5 mS cm–1). These ionogels were successfully applied to sensing devices, and the resulting sensors exhibited excellent linearity, sensitivity, repeatability, and operational durability. Furthermore, the sensors accurately detected the movements of various vehicle parts, including the suspension damper, door hinge, and seat coil, indicating the potential of mechanically tough ionogels for multipurpose sensing systems.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":null,"pages":null},"PeriodicalIF":11.4,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142208520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, taking temperature and acid as external stimuli, variations in the RTP characteristics can be observed in terms of the lifetime and color scales. Moreover, the detailed variations can be controlled by the dynamic regulation of electrostatic interactions between RTP units and the pyridine core, which can be further detected by the corresponding crystal structures under any conditions.

Therefore, development of a self-evaluation strategy is urgently needed. To the best of our knowledge, there is no multimodal self-evaluation strategy. Herein, we design an integrative probe (CPT-SS-DEVD-HCy) for tumor therapy and dual-modal self-evaluation imaging. In tumor cells, the high concentration of glutathione (GSH) specifically induces CPT-SS-DEVD-HCy to release CPT, which generates apoptosis with the activation of caspase-3 (Casp-3). Subsequently, activated Casp-3 further specifically cleaves peptide substrate to release hemicyanine (HCy) dye, thus generating a fluorescent/photoacoustic (FL/PA) dual-modal signal for self-evaluation imaging. Cell experiments show that CPT-SS-DEVD-HCy can effectively kill tumor cells through GSH-instructed CPT release and further image Casp-3 activity during apoptosis with a 5.1-/6.4-fold increased FL/PA signal. Moreover, CPT-SS-DEVD-HCy displays a high tumor inhibition effect and is competently able to self-evaluate the tumor therapeutic effect in vivo. We envision that this work will be helpful for developing more self-evaluation imaging probes in the future.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":null,"pages":null},"PeriodicalIF":11.4,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142208521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By use of in situ Kelvin probe force microscopy (KPFM), we identified that photoelectrons generated over CdS were transferred to Shewanella putrefaciens (S. putrefaciens) to enhance the excellent uranium removal performance of the S. putrefaciens–CdS biohybrid.

To address this daunting issue, a multimodal antibacterial strategy that combines exogenous and endogenous stimulations is proposed. A novel two-dimensional heterojunction (termed MXP HJs) is developed by in situ growth of the metal–organic frameworks (MOFs) onto the MXene via the dielectric barrier discharge technique. Under light irradiation, MXP HJs exhibit excellent photocatalytic and photothermal performance to provide exogenous stimulation for killing bacteria. In addition, the MXP HJs promote electron transfer at the interfaces between the MXP HJs and bacteria, and this inhibits bacterial ribosomal pathways, resulting in endogenous antibacterial activity. Furthermore, MXP HJs can significantly promote wound healing through bacterial clearance, collagen deposition, and angiogenesis. Thus, this work lays the foundation for the development of a photocatalytic HJ platform that can be used in antibacterial applications for infectious wound repair.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":null,"pages":null},"PeriodicalIF":11.4,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142208524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
