Summary: A new type of aptamer-functionalized pH-responsive polymer-modified magnetic nanoparticles (ApMNPs) was developed for specific enrichment and sensitive determination of lactoferrin (Lf) in complex matrixes. The Lf-binding aptamers were conjugated onto pH-responsive polymer-modified magnetic nanoparticles (pMNPs) to prepare Lf-ApMNPs, which showed good selectivity and adsorption capacity for Lf. The introduction of pH-responsive monomer effectively regulated the adsorption-desorption process, making it a facile and efficient approach for the determination of targets in biological samples.

Summary: In this manuscript, a new magnetic porous beta-cyclodextrin polymer nanoparticle (CA-PCDP@MNPs) was developed for efficient removal of radioactive uranium (U(VI)) from water. The CA-PCDP@MNPs showed a well-developed porous structure, high specific surface area, and abundant oxygen-containing functional groups, providing sufficient active sites for chelating uranyl ions. The CA-PCDP@MNPs also exhibited fast response magnetic recovery ability and excellent regeneration and recycling ability. These findings suggest that the CA-PCDP@MNPs have great potential in practical applications for nuclear wastewater treatment.

Summary: Heteroatom-doped carbon nitride (C3N4) materials were investigated as supports for Au nanoparticles, which were anchored on sulfur-doped carbon nitride nanosheets (AuNPs@SCNN) and used as a catalyst for arsenic electroreduction. The synthesis of novel SCNN was achieved through a simple thermally induced copolymerization route using ammonium persulfate (APS) as a sulfur source. The integration of SCNN with AuNPs improved the assembly quality and interface, leading to enhanced catalytic activity. The composite (AuNPs@SCNN/GCE) modified glassy carbon electrode exhibited enhanced electrochemical responses for the electrocatalytic reduction of arsenic.

Summary: Biomaterials for tissue scaffolds play a crucial role in tissue engineering and regenerative medicine. Choosing the right biomaterial and cells for implantation is essential for targeted reconstructive therapies. Modern biomaterials need to not only provide mechanical support for implanted cells and match the expected mechanical strength of artificial tissue, but also ensure cell survival and influence their desired differentiation.

Summary: The mechanism of the inner filter effect (IFE) can be effectively utilized in the design of innovative IFE-based sensors using resonance Rayleigh scattering (RRS) technique. Silver nanocubes (Ag NCs) with tunable extinction spectra were employed as RRS probes, and three typical analytes, doxorubicin (DOX), sunitinib (SUN), and Alizarin Red S (ARS), were considered. The results demonstrated the feasibility of the newly developed IFE mechanism as an attractive analytical technique for measuring different analytes.

Summary: In this study, a highly sensitive electrochemical sensor was developed for the detection of ultra-trace levels of Pb2+. The sensor was modified with an in-situ electroplated bismuth film and a nanocomposite of a recently synthesized melamine based covalent organic framework and Fe3O4 nanoparticles. The combination of Fe3O4@SNW1 and the bismuth film significantly enhanced the sensitivity of the sensor towards Pb2+. The optimized sensor showed a linear response in the concentration range of 0.003-0.3 μmol L-1 with a detection limit of 0.95 nmol L-1. The sensor demonstrated good selectivity towards Pb2+ and was successfully applied for the determination of Pb2+ in different edible specimens.

Summary: We reported a novel electrochemical sensor for the indirect determination of cyanuric acid (CA) using the complex formation between CA and melamine (MEL) for the first time. The sensor utilized the electrochemical conversion of MEL to electroactive polymelamine, with the decline in current intensity upon the addition of CA serving as the sensor response. A calibration curve was constructed using square wave voltammetry, with a limit of detection of 80.28 mu mol L-1. The proposed method showed excellent recovery range (91.2-101.0%) for real sample analysis.

Summary: We report on the synthesis and characterization of a dual stimuli-responsive hydrogel for pH and temperature-sensitive delivery of curcumin (CUR) anticancer drug. The release of CUR from the hydrogel was higher at acidic pH values, and the hydrogel remained stable at 37 degrees C. To enable thermal responsivity, polydopamine nanoparticles were embedded in the hydrogel. The GGPDNCs hydrogel is engineered to respond to both pH and temperature stimuli.

Summary: In this research, the complexation of a newly synthesized covalent organic framework (schiff base network1) with different cations, including Hg2+, was studied. The results showed that schiff base network1 had a stronger interaction with Hg2+ compared to other cations, making it a potential ionophore for the development of a Hg2+ potentiometric sensor. A Hg2+ selective PVC membrane coated graphite electrode was successfully created using schiff base network1, which exhibited excellent response and sensitivity for the detection of Hg2+ in a wide range of concentrations. The electrode also demonstrated good performance in non-aqueous environments and had a long lifespan.

Summary: Rhabdomyosarcoma is a rare cancer that affects skeletal muscle, primarily in children and young adults. The treatment strategies for this disease include multi-agent chemotherapies following surgical resection and radiotherapy. This review provides a detailed clinical understanding of rhabdomyosarcoma, including its classification, diagnosis, and treatment strategies. The impact of apoptosis, macro-autophagy, and the unfolded protein response on chemotherapy response is discussed. Additionally, the use of in vivo mouse and zebrafish models and in vitro three-dimensional bioengineering models for screening future therapeutic approaches and promoting muscle regeneration is explored.
