Summary: This study achieved effective adsorption of GenX by using chitosan (CS) modified adsorbent. The prepared CS-DEO-APTES adsorbent showed high adsorption capacity and excellent stability. Kinetic and isothermal data revealed chemisorptive interactions between GenX and CS-DEO-APTES with a uniform distribution of adsorption sites. GenX-saturated beads were successfully regenerated multiple times. Density functional theory calculations indicated that electrostatic interactions primarily influenced the adsorption of GenX. These results highlight the effectiveness of the CS-DEO-APTES adsorbent for removing GenX from aqueous solutions.

Summary: Lung cancer is the second leading cause of cancer-related deaths. Osimertinib mesylate (OSM), a tyrosine-kinase inhibitor, is effective for non-small cell lung cancer (NSCLC), but has limitations and side effects. The development of OSM-loaded biodegradable polycaprolactone nanoparticles (PCL-NPs) and chitosan fabricated OSM-loaded PCL-NPs (CSPCL-OSM-NPs) aims to achieve active targeting of OSM in cancerous lung tissue, improving efficacy and reducing side effects. The optimized PCL-OSM-NPs and CS-PCL-OSM-NPs showed enhanced anticancer activity and safety, making them a promising option to treat NSCLC.

Summary: Dexamethasone (DEX) has been used for bone regeneration and anti-inflammatory purposes for over a decade. It has potential for inducing bone regeneration as part of osteoinductive differentiation medium, especially in in vitro culture models. However, its use is limited due to cytotoxicity, particularly at higher concentrations. Evaluating DEX activity and dosage in a three-dimensional (3D) environment is crucial for bone tissue development. This review examines the advantages of a 3D approach for controlled DEX delivery, discusses biomaterial-based therapeutic delivery approaches, and explores future strategies for efficient DEX delivery.

Summary: In order to address the presence of fluoroquinolone antibiotics in aquatic environments, it is necessary to design a semiconductor photocatalyst with excellent photocatalytic efficiency. This study explored the performance of MnNb2O6/g-C3N4 composites in the photocatalytic degradation of ciprofloxacin and tetracycline-HCl antibiotics. The enhanced photocatalytic activity of MNO/g-CN was found to be due to the electron's shifting between the MNO and g-CN sheets, promoting the formation of photo-generated e(-)/h(+) pairs, indicating the existence of a low-waste, high-performance material for eradicating ciprofloxacin and tetracycline-HCl from wastewater.

Summary: A ratiometric fluorescent probe based on o-phenylenediamine-derived carbonized polymer dots (o-PD CPDs) was developed for real-time intracellular detection of singlet oxygen (1O2). The o-PD CPDs can produce 1O2 and selectively quench the yellow fluorescence, allowing for the selective detection of 1O2 against other reactive oxygen species (ROS). The probe was successfully applied to monitor 1O2 level in the intracellular environment and detect 1O2 and other ROS species in an inflammatory neutrophil cell model.

Summary: The design of therapeutic nanoplatforms based on fluorescent carbon dots (CDs) has become a viable strategy due to their aqueous solubility, biocompatibility, and ease of functionalization. Through doping heteroatoms into CDs structures, N-, Cl-, and S-doped CDs (NClS/CDs) and Se-, N-, and Cl-doped CDs (NClSe/CDs) were synthesized with superior optoelectronic properties. These doped CDs showed enhanced quantum efficiencies and were used for photodynamic therapy (PDT) by efficiently producing reactive oxygen species (ROS) under laser irradiation. Nanovesicles (NVs) loaded with camptothecin (CPT) drug were designed using NClS/CDs, which exhibited ROS-triggered drug release. The study presented an image-guided PDT and chemotherapeutic platform based on the NVs, showing potential for future cancer treatment.

Summary: A next generation of wearable self-powered wound dressing is developed, which can be activated by diverse stimuli from the patient's body and provide on-demand treatment for both normal and infected wounds. The dressing utilizes thermocatalytic bismuth telluride nanoplates (Bi2Te3 NPs) functionalized onto carbon fiber fabric electrodes, generating hydrogen peroxide to effectively inhibit bacterial growth at the wound site. The integrated electrodes connected to a wearable triboelectric nanogenerator (TENG) accelerate wound closure by enhancing cellular proliferation, migration, and angiogenesis. This self-powered dressing has great potential in personalized and user-friendly wound care with improved healing outcomes.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
