Summary: This study demonstrates the precise positioning of enzyme glucose oxidase within block-copolymer brush nanostructures for the design of multifunctional biosensors. By controlling the polymer brush nanostructure, the researchers achieved low detection limit, broad detection range, and reliable "OFF" state. Through a combination of characterization methods, the unique properties of the hierarchical biocatalytic polymer brushes were confirmed for responsive biosensor design and complex multi-functional gating platforms.

Summary: This research examined how linear or branched brushes on porous ultrafiltration membranes affect their antifouling behavior. By modifying polyethersulfone membranes, different polymer brushes were created using a one-pot lithiation/acylation process. Surface analyses showed differences in brush architecture and higher grafting for linear brushes compared to branched ones. Colloidal probe lateral force atomic force microscopy (LFM) demonstrated that lower branching degree poly(SBMA-co-MBAm) had ideal hydration-lubrication properties. Fouling experiments with bovine serum albumin and dextran showed that both linear and branched modifications reduced fouling compared to the pristine membrane. The study also found that an optimal degree of branching can limit foulant adsorption.

Summary: Zinc sulfide embedded reduced graphene oxide nanocomposites (ZnS-rGO) were prepared via a simple precipitation method. The as-prepared ZnS-rGO exhibited efficient sunlight-promoted selective degradation of Congo Red (CR) in a short time, even in the presence of spiking industrial wastewater. Under pseudo-first-order kinetics, the ZnS-rGO achieved similar to 98% degradation of CR dye with a rate constant of 0.0266 min-1. Sunlight as a sustainable energy source outperformed artificial bulb light by producing better results (approximately three times higher) during photocatalytic degradation of similar concentrations of CR dye. The study also investigated the effect of dye concentration and catalyst loading on the photocatalytic degradation efficiency.

Summary: This study investigates the influence of graphene oxide (GO) on the properties of electrospun recycled poly(ethylene terephthalate) (rPET) composite nanofiber membranes. Results show that GO loadings of less than 0.5 wt % lead to smoother fiber surfaces, enhancing hydrophilicity and crystallization performance. Ultimately, maintaining the GO content at a maximum of 0.5 wt % is preferable for maximizing hydrophilicity and filtration permeation flux in desired applications.

Summary: This study synthesized a three-dimensional network structure catalyst 3D-rGO/BP/ZnO with the properties of easy separation and recycle, which exhibited synergistic effect between adsorption and photocatalysis. The adsorption experiments showed that the pseudo-second-order kinetic model and Freundlich model were appropriate for describing adsorption behavior. The photocatalytic experiment revealed that 3D-rGO/7-BP/ZnO had the best photocatalytic performance, degrading 93.0% of RhB in 120 min. 3D-rGO/BP/ZnO heterostructure could boost the separation of photogenerated electrons and holes, and superoxide radicals (.O-2) were the main active species. After three catalytic cycles, the photocatalysts exhibited excellent stability. This study offered a fresh perspective on the effective use of photocatalyst in environmental rehabilitation.

Summary: This study aimed to enhance the bioavailability of rosmarinic acid, a bioactive compound with high anticancer activity, by encapsulating it in tetrasulfide-based porous organosilica nanoparticles. The synthesized nanoparticles were small in size and had a high surface area and an average pore diameter. The nanoparticles showed effective accumulation in cancer cells without toxicity to normal cells. Treatment with rosmarinic acid-containing nanoparticles resulted in significant cell death in cancer cells. Overall, these findings suggest that the synthesized nanoparticles can enhance the pharmacological effects of rosmarinic acid.

Summary: Plasma protein binding plays a crucial role in the pharmacokinetics and pharmacodynamics of therapeutic bioactive materials. In this study, the interaction of nordentatin, a member of coumarins, with human alpha-1 acid glycoprotein (AGP) was investigated, and the anticancer potency of nordentatin against human colorectal cancer cells was evaluated. The results showed that nordentatin binds to AGP through a static quenching mechanism and exhibits inhibitory effects on the growth of HCT-116 cells by increasing intracellular ROS and [Ca2+] levels and triggering apoptosis-related gene overexpression. Therefore, nordentatin could be a promising plant-based therapy for colorectal cancer.
