Summary: In this study, 3D flower-like structured organic-inorganic hybrid nanoflowers (hNFs) with various lipases and graphene quantum dots (GQDs) were prepared and characterized. The addition of GQDs significantly increased the activity of the lipase hNFs. The lipase@GQDs hNFs showed higher activity compared to free lipase and other hNFs without GQDs, and also exhibited improved pH and thermal stability.

Summary: Reliable H2O2 sensors for in situ cellular monitoring under drug stimulation can be developed by using graphene and shape-controlled gold nanostructures. The as-synthesized nanostructured H2O2 sensors showed high sensitivity (5.07×10-4 mA μmol L-1 cm-2) and good detection capability (the lowest detection limit is 4.5 μmol L-1 (S/N = 3)). The electrochemical biosensor demonstrated remarkable sensitivity, accuracy, and rapidity compared with traditional enzymatic detection kits. This technology can be applied to assess the antitumor properties of candidate drugs and inspire developments for personalized health care monitoring and cancer treatment.

Summary: Fluorescent hydrogels are promising materials for portable biosensors used in point-of-care diagnosis. They have a greater binding capacity for organic molecules compared to immunochromatographic test systems, and fluorescent detection is more sensitive than colorimetric detection. The properties of hydrogel matrix can be finely tuned for better analyte compatibility, and hydrogel biosensors can be made reusable and suitable for studying dynamic processes in real time.

Summary: In this paper, Ag-I was added to Cu4I4(Gly)(3) cluster to form Cu3I4(Gly)(3)/Ag and introduce impurity energy levels, enhance light absorption efficiency, and construct excision structures to improve luminous efficiency. However, excessive surface defects resulted from this addition affected the luminous efficiency of fluorescent materials. By adding MXene to Cu3I4(Gly)(3)/Ag, Cu3I4(Gly)(3)/Ag/x·MXene (x=0 to 1.0 wt%) was formed to reduce surface imperfections and build heterojunctions, thereby improving the separation of photogenerated electrons and holes. Cu3I4(Gly)(3)/Ag/0.6·MXene emitted orange-red light, broadened the UV-vis absorption range, reduced fluorescence lifetime by 24%, and increased quantum efficiency by 136%. This work suggests that Cu3I4(Gly)(3)/Ag/x·MXene could be attractive alternatives to toxic lead halide perovskites and unstable copper(I) halides for optical applications.

Summary: AFB1 contamination in edible oils is a significant concern for safety. Enzymatic degradation provides a promising method, but its efficiency is hindered by low enzyme activity and stability. In this study, an amphipathic laccase-inorganic hybrid nanoflower (Lac NF-P) was developed as a biocatalyst to degrade AFB1 in peanut oil. Lac NF-P exhibited 134- and 3.2-fold higher degradation efficiency compared to laccase and Lac NF, respectively. Within 3 hours, Lac NF-P reduced AFB1 concentration from 50-150 μg/kg to less than 0.96 μg/kg in peanut oil without affecting its quality. This study opens up new possibilities for developing biocatalysts to detoxify mycotoxins in edible oils.

Summary: The research introduces a feasible strategy for designing an excellent acidic and alkaline hydrogen evolution electrocatalyst using the MoS2@Mo-S-C3N4 heterostructure with transferable active centers. Mo-S-C3N4 is regarded as a synergistic catalyst for acidic hydrogen evolution, while MoS2 acts as a co-catalyst for alkaline hydrogen evolution. The coordination of electrons between interfaces achieves a synergistic balance, providing optimal sites for reactant adsorption. This electrocatalyst shows better overpotentials in acidic and alkaline media compared to previous reports.

Summary: Seven hierarchical flower-like hemoglobin-phosphate organic-inorganic hybrid nanomaterials were synthesized, with Ca2+, Mn2+, Fe2+, Co2+, Ni2+, Cu2+ and Zn2+ as inorganic components. The hemoglobin-Cu-3(PO4)(2)·3H2O nanoflowers exhibited significantly higher catalytic activity than Hb, due to conformational transformation and abundant Cu(2+)/Fe3+ active sites. This synthesis method allows for the creation of diverse monometallic-ionic, polymetallic-ionic, and polyvalent metal-ion nanoflowers.

Summary: In this study, we designed and prepared a 1T/2H-MoS2 material with increased interlayer spacing to enhance the catalytic activity for the hydrogen evolution reaction (HER). The increased interlayer spacing exposes more active sites and provides larger channels for ion transport. The combination of conductive 1T and 2H phase MoS2, along with the presence of phase boundaries, further improves the catalytic activity. The prepared catalyst exhibits superior HER performance with low overpotential and low Tafel slope, and shows remarkable electrochemical stability under acidic conditions.
