In this paper, MWCNTs@TiO₂ composite materials were prepared by the hydrothermal synthesis method and then added into the three dimensional framework constructed by PAM (polyacrylamide) and PEG (polyethylene glycol) to obtain hydrogels with EMI functionality. It was found that in the M@T/PAM-4 (MWCNTs@TiO₂/PAM-4) hydrogel, due to the fact that TiO₂ particles were loaded on the surface of MWCNTs, its cross section presented a granular shape. As the content of MWCNTs increased, the EMI SE_T of the hydrogel increased, with the M@T/PAM-4 hydrogel reaching 29 dB. The electrical conductivity and mechanical properties also increased accordingly. Compared with the pure PAM hydrogel, they were respectively improved by 626 % and 24.5 %, which was attributed to the formation of a conductive network by MWCNTs and the enhancement of interfacial polarization, etc. Meanwhile, the water retention rate of the M@T/PAM-4 hydrogel could still reach 34.1 % after 8 h. Moreover, it also had a relatively high water content of 69.08 %. Therefore, This improves the application value and development prospects of the hydrogel in fields such as Electromagnetic (EM) shielding.</div></div>","PeriodicalId":48517,"journal":{"name":"Materials Today Nano","volume":"29 ","pages":"Article 100606"},"PeriodicalIF":8.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143562356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, challenges arise due to the presence of numerous interfering ions that complicate glucose monitoring in sweat.

Subsequently, the AgNCs were stably adsorbed onto the surfaces of nano mica platelets (NMPs) via one-step synthesis to form AgNC/NMP nanohybrid surface-enhanced Raman spectroscopy (SERS) substrates with a three-dimensional (3D) lightning rod effect. The NMPs (thickness: 1–3 nm; length and width: approximately 300 nm) had a high surface-area-to-volume ratio and numerous hydroxyl groups on their surfaces, which provided the AgNCs with a good platform for stabilization and growth. When used in surface-enhanced Raman scattering for the biomolecular detection of adenine, the AgNC/NMP nanohybrids exhibited a better limit of detection (LOD) concentration of 10⁻¹⁰ M compared with AgNCs, an enhancement factor (EF) of 4.38 × 10⁹, and a relative standard deviation of 8.52 %. This may be attributed to the hot spots generated along the z-axis by the AgNC/NMP nanohybrids, which created a 3D hot spot effect. The AgNC/NMP nanohybrids also demonstrated an LOD of 10² CFU/mL in the detection of <em>Staphylococcus aureus.</em> To further improve detection sensitivity and biocompatibility, the AgNC/NMP nanohybrids were modified with zinc quantum dots (ZnO QDs) for the synthesis of AgNC/NMP/ZnO QD nanohybrids. When used for the biodetection of adenine, the ZnO-QD-modified nanohybrids exhibited a higher signal intensity compared with the AgNC/NMP nanohybrids, with an increase in the EF to 6.37 × 10⁹. The increase in intensity was attributed to the chemical enhancement effect in SERS. Excellent characteristic signals were also obtained when the AgNC/NMP/ZnO QD nanohybrids were used for the detection of the other three bases of DNA. Finally, the good biocompatibility and large specific surface area of the ZnO QDs enhanced the effects of SERS in bacterial detection, with a further decrease in the LOD to 10 CFU/mL.

The keratin tags driven from type I keratin of K31were firstly screened through the self-assembly interaction between recombinant K86 (RK86) with different lengths of RK31, that were subsequently used to fuse with various enzymes to connect RK86 microparticles for immobilization.
