In this work, a conductive montmorillonite/amphiphilic polyurethane (CMMT/APU) hydrogel-based triboelectric nanogenerator (CA-TENG) is constructed by integrating a conductive montmorillonite-modified hydrogel electrode with a contact-separation triboelectric configuration. Polytetrafluoroethylene (PTFE) and nylon are selected as the triboelectric layers, while the CMMT/APU hydrogel is employed as the flexible conductive electrode. Owing to the cooperative effect between conductive montmorillonite and the amphiphilic polyurethane network, the hydrogel exhibits good flexibility, structural stability, and mechanical adaptability, and the composition containing 5% CMMT presents the most suitable tensile performance for device fabrication. The optimized CA-TENG delivers a peak open-circuit voltage ([Formula: see text] of 777[Formula: see text]V, a short-circuit current ([Formula: see text] of 39[Formula: see text][Formula: see text]A, and a transferred charge ([Formula: see text] of 250[Formula: see text]nC, together with a maximum output power of 598[Formula: see text][Formula: see text]W. Moreover, the device shows stable output under different working frequencies, separation distances, and humidity conditions, and it can effectively distinguish walking, running, jumping, and joint-bending motions, demonstrating strong potential for self-powered wearable-motion monitoring and biomechanical analysis.","PeriodicalId":397,"journal":{"name":"Nano-Structures & Nano-Objects","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148305552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This effect reduces the electron–hole overlap and results in a decrease of both exciton and biexciton binding energies in larger quantum dots, while in smaller structures (heights below ∼2 nm) the confinement dominates, leading to an opposite trend and partial stabilization of biexciton states.

The synthesis was optimized by varying catalyst concentration (0.5–2.0 M) at 80 °C for 3 h.

The resulting biologically synthesized nanoparticles were subjected to a post-synthesis annealing process at 400, 500, and 600 °C, which enabled the assessment of the temperature-dependent structural, optical, magnetic, antimicrobial, and anticancer characteristics. X-ray diffraction studies confirmed the successful formation of the bimetallic phases, which exhibited a progressive enhancement in crystal perfection and lattice order, validated through FWHM and Williamson-Hall plot analyses. FT-IR studies confirmed the role of the functional groups present in the phytochemicals, which contributed towards the improved metal-oxygen bonds after the annealing process. UV-Vis studies clearly indicated the improved absorbance, which was accompanied by the modification of the band structures, especially in the 500 °C annealed sample. SEM and DLS studies clearly revealed the progressive development from the agglomerated nanoparticles towards the defined nanostructures at the 500 °C annealed sample, which was later accompanied by the development of larger grains at the 600 °C annealed sample.

Results from the antimicrobial studies clearly indicated the strong antimicrobial activities towards the Gram-positive and Gram-negative bacteria, which were observed in the annealed samples, which exhibited improved inhibition compared to the unannealed sample. Finally, the cytotoxicity studies, which were conducted using the MTT assay, clearly demonstrated the dose-dependent cytotoxicity towards the breast cancer cells, indicating the improved anticancer efficacy.
