“…Next, we applied X-ray diffraction (XRD) to further prove formation of coordination bonds and hydrogen bonds of the directly self-assembled nanoparticles in wide-angle patterns (Fig. 2 e) [ 33 ]. Compared with BA, the diffractogram of BA-Al NPs showed two strong sharp reflections at 2θ = 31.745° (d = 2.8164 Å) and 2θ = 45.456° (d = 1.9937 Å).…”

Background Oral administration of insulin (INS) could be absorbed into systemic circulation only if the carrier protected it from the hostile gastrointestinal conditions. However, traditional macromolecular carriers have not totally overcome challenges in addressing these biological barriers. Result In this study, inspired by small molecule natural products (SMNPs), we demonstrate the multi-functional self-assembly nanoparticles (BA-Al NPs) originating from baicalin (BA) and AlCl3 through coordination bonds and hydrogen bonds. As a novel carrier for oral insulin delivery (INS@BA-Al NPs), it displayed effective capacity in pH stimuli-responsive insulin release, intestinal mucoadhesion and transepithelial absorption enhance. Meanwhile, BA improved the paracellular permeability for insulin absorption, because of its downregulation at both mRNA and protein level on internal tight junction proteins. In vivo experiments exhibited remarkable bioavailability of INS and an ideal glucose homeostasis in the type I diabetic rat model. Conclusion This study offers a novel frontier of multi-functional carriers based on SMNPs with self-assembly character and bioactivity, which could be a promising strategy for diabetes therapy.

“…The composition can be adjusted in a certain range, and the layered structure has a large specific surface area, which makes them have high adsorption performance in a variety of adsorption substrates [12,13]. However, due to the lack of specific function and structure, the adsorption performance of pristine LDH is limited [14]. In addition, it is critical to fabricate high performance materials by compounding other components with functionalities, pristine LDH can hardly meet the requirements.…”

Cobalt (Co) ion is a common heavy metal ion and the main metal ion in nuclear wastewater. However, the study on the absorption for Co(II) is not sufficient. Herein, a novel ES-layered double hydroxide (LDH) is prepared by intercalated ethylenediaminetetraacetic acid disodium salt (EDTA) and sodium dodecylbenzene sulfonate (SDBS) in a magnesium, iron pristine LDH, which is subsequently used for ES-LDH@carboxymethyl cellulose (CMC) composite aerogel. The results of Fourier transform infrared spectroscopy, X-ray diffraction spectra and thermogravimetric analysis shows successfully preparation of intercalated LDH. The pore morphology, specific surface area and pore size distribution of the composite aerogels are characterized by scanning electron microscope and Nitrogen-BET curves. The significantly improved adsorption capacity, adsorption kinetics and isotherms the absorbents on Co(II) are systematically revealed. This study thus provides an important understanding and path for dealing with the threat of Co(II).

This paper discussed the preparation of palladium (PdO) and nickel (NiO) oxides nanoparticles (NPs). These nanoparticle oxides were successfully synthesized by thermal decomposition method using complexes of Schiff base of 4-aminoantipyrine derivative as a precursor at temperature of 800 °C. Schiff base (AEB) was synthesized via a reaction between 4-aminoantipyrine, benzaldehyde and ethylenediamine at stoichiometric 1:1:1 molar ratio at 60 °C for 2 h. The suggested structure of Schiff base was predicted by elemental analyses, 1 Hand 13 C-NMR, FT-IR, UV-Vis, mass, and thermogravimetric (TGA) techniques. The prepared oxides were characterized by Fourier transform infrared spectrometry (FT-IR), powder X-ray diffraction (XRD), and transmission electron microscopy (TEM). From XRD data, the final thermal decomposition products are PdO and NiO with the particle size of 28 and 13 nm, respectively. From the TEM micrographs, the particle size are in good agreement with XRD data and indicate that the products have uniformly spherical particles. The synthesized PdO and NiO oxide nanoparticles were used to removal of the methylene blue (MB) from aqueous solution. Adsorption of MB dye onto the synthesized oxide NPs were performed based on various parameters such as effect of adsorbent dosage, contact time and pH of the pollutant media. The results suggest that the PdO and NiO NPs are excellent adsorbent for the removal of MB dye.
