“…The study of photocatalytic material is of utmost relevance to meet the global energy demand with little environmental damage [5][6][7]. Recent years have seen a significant amount of interest in the concept of producing chemical energy from solar energy using effective and environmentally acceptable photocatalysts made of mixed metal oxides [8].Additionally, Bi12GeO20 exhibits optical activity, and the external magnetic field can change that optical activity [9]. These photocatalysts can be divided into three groups based on the electronic configuration of their core metal ions.…”

Increasing water pollution poses a serious threat to both humankind and animals in the current situation. Low cost optical especially photocatalytic material is of utmost relevance to improve situation and meet the global energy demand with little environmental damage. The aim of this study is to develop low-cost low temperature reproducible method to synthesize multifunctional material suitable for degradation of a very dangerous water contaminant dye under visible light exposure. A semiwet chemical route was used to synthesize a multifunctional Bi12GeO20 compound suitable for photocatalytic activity for the degradation of Rhodamine B (RhB) dye under visible light exposure. Bi12GeO20 (BGO) ceramic with polycrystalline structure was prepared successfully e using a low temperature chemical process. X-ray powder diffraction reveals that single-phase BGO ceramic was formed. Nanosized BGO ceramic particles that had been stabilized, XRD and TEM to showed particle sizes in the 60-10 nm range. Due to the favorable band gap (2.72 eV) and the sillenite type Bi12GeO20 exhibits strong photocatalytic activity for the degradation of Rhodamine B (RhB) dye under visible light exposure.

PLA fibers containing metronidazole as the active component were produced by electrospinning from a solvent mixture of dichloromethane (DCM) and dimethyl sulfoxide (DMSO). The DMSO content of the spinning solution changed between 0 and 25 vol% in 5 vol% steps. The fibers were dried at different temperatures, and processes taking place during fiber production and drying were followed by thermogravimetric analysis and differential scanning calorimetry. The morphology and structure of the fibers were studied by microscopy and X-ray diffraction. The mechanical properties of fiber mats and the release of the drug were also determined as a function of processing and drying parameters. The results showed that several processes take place during the production and subsequent handling of the fibers including the evaporation of the solvent (DMSO), the crystallization of the polymer, the changing of composition, phase separation and the consequent partitioning of the drug. The crystalline structure of the fibers changes considerably during drying which determines their mechanical properties. The rate of evaporation and crystallization is in the same order of magnitude. The rate of both processes increases considerably with temperature, but does not depend strongly on the amount of DMSO in the spinning solution. Both the amount of the drug released and the rate of release cover a wide range depending on the parameters of the preparation technology. The large range of mechanical and functional properties obtained allows the control of the kinetics of drug release to some extent.

Development of a Nanoformulation for Oral Protein Administration: Characterization and Preclinical Orofacial Antinociceptive Effect

et al. 2022

Nanoencapsulation is a valid alternative for the oral administration of peptide drugs and proteins, as nanoparticles protect them from proteolytic degradation in the gastrointestinal tract and promote the absorption of these macromolecules. The orofacial antinociceptive effect of frutalin (FTL), through the intraperitoneal route, has already been proven. This study aimed to develop, characterize, and evaluate the orofacial antinociceptive activity of an oral formulation containing FTL in acute and neuropathic preclinical tests. The analyzed sample did not show any cytotoxicity; 52.2% of the FTL was encapsulated, the size of the nanocapsules was less than 200 nm, the polydispersion was 0.361 and the zeta potential was -5.87 millivolts. Nanoencapsulated FTL administered by oral route had an orofacial antinociceptive effect in acute and neuropathic rodent models. The antinociceptive effect of FTL was prevented by ruthenium red, but not by camphor. FTL reduced Trpv1 gene expression. FTL promotes orofacial antinociception probably due to the antagonism of TRPV1 channels and the nanoformulation represents an effective method of administering this protein orally.
