Summary: Flexible hydrogel sensors have found extensive applications in electronic devices due to their suitable mechanical properties and excellent biocompatibility. However, the current methods for synthesizing reduced graphene oxide (rGO) face limitations in terms of reduction degree and dispersion, which hinder the conductivity of graphene hydrogels. In addition, hydrogels are prone to inflammation and bacterial infections, affecting sensor stability over time. This study successfully synthesized a hydrogel with commendable conductivity and sensor performance by modifying and reducing GO using a heparin-polydopamine complex. The multifunctional nature of this hydrogel makes it a promising candidate not only as an epidermal sensor but also for chronic wound treatment.

Summary: The study focused on the effect of polydopamine (PDA) modification on the removal of a cationic dye (methylene blue) and an anionic dye (Congo red) from waters using -Fe3O4-NH2/ GO/CDP-CA composites. It was found that the PDA/Fe3O4-NH2/ GO/CDP-CA composite exhibited higher adsorption capacities for both dyes compared to -Fe3O4-NH2/GO/CDP-CA. The sorption behaviors were explained by the surface-charged properties of the composites. Furthermore, the composites showed good recyclability and reusability.

Summary: Electrochemical analysis has emerged as a novel method for plant analysis, allowing the collection of signals related to electrochemically active substances and enabling plant species identification. Moreover, these signals can be utilized for studying plant phylogeny. In this study, electrochemical fingerprint patterns of Malvaceae leaves were obtained using an established methodology, and after processing, the fingerprints exhibited distinct differences. Three different recognition models were employed for analyzing the electrochemical fingerprints, with linear support vector classification achieving high accuracy in species identification when combining the signals collected in different buffer solutions. Additionally, the collected fingerprints were utilized for phylogenetic investigation, resulting in the clustering of 18 species into three groups, with species from the same genus clustered together. The obtained dendrogram from electrochemical fingerprinting was compared with morphological and complete chloroplast genome-based results.

Summary: The present study focused on using phospholipid fatty acid (PLFA) technology to investigate the rhizosphere soil microorganisms of Minghui 86 (MH) and Yangdao No.6 (YD) rice at different growth stages. The results showed that the rhizosphere soil microorganisms of MH and YD had distinct sensitivities to exogenous phosphorus and had a certain inhibitory effect on rice enhancement. The sensitivity of rice root soil microorganisms to exogenous phosphorus also varied in different growth stages of rice. Bacteria were the dominant microorganism in the soil microbial community of rice roots, and the addition of exogenous phosphorus had a certain impact on the structure of the soil microbial communities. Through analyzing the microbial community characteristics, the study provided further understanding of the effect of exogenous phosphorus on the microbial community characteristics of rice rhizosphere soil and its impact on ecological functions.
