AI Article Synopsis

  • Chemotherapy often leads to adverse effects, prompting the exploration of natural drugs like Quercetin (QC) and targeted delivery systems.
  • Researchers encapsulated QC in a synthesized nanocarrier made of FeO, starch, and polyvinyl alcohol (FeO/S/PVA), which showed effective drug loading and release properties.
  • The study demonstrated that this nanocarrier effectively delivered QC to HepG2 cancer cells, showing promising results in cell viability assays, indicating its potential as a targeted cancer treatment.

Article Abstract

The common adverse effects of chemotherapy are the reason for the use of effective, natural drugs and targeted administration to specific areas. On the one hand, Quercetin (QC) has positive effects as a natural anticancer agent. On the other hand, FeO, as nanoparticles (NP) with clinical properties and high porosity, can be a suitable carrier for drug loading and controlled release. In this study, QC was encapsulated in a synthesized FeO/Starch/Polyvinyl alcohol nanocarrier (FeO/S/PVA NC). Characterization of the NC was done by Fourier transforms infrared spectroscopy (FTIR), X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), vibrating sample magnetometer (VSM), zeta potential and Dynamic light scattering (DLS). The percentage of drug loading (DLE) and encapsulation efficiency (EE) of QC in the NC containing FeO nanoparticles was 47 % and 86.50 %, respectively, while it was 36 % and 73 % in the NC without FeO. QC profile release in acidic and natural mediums showed controlled release and pH dependency of the NC. Viability of L929 and HepG2 treated cells with the FeO/S/PVA/QC was demonstrated by MTT staining which was in agreement with flow cytometry. The results show that FeO/S/PVA is a suitable NC for the targeted delivery of QC as a drug against HepG2 cancer cells.

A microbial fuel cell (MFC) is a modern, environmentally friendly, and cost-effective energy conversion technology that utilizes renewable organic waste as fuel, converting stored chemical energy into usable bioelectricity in the presence of a biocatalyst. Despite advancements in MFC technology, several challenges remain in optimizing power production efficiency, particularly regarding anode materials and modifications. In this study, low-cost biosynthesized iron oxide nanoparticles (FeO NPs) were coated with a polyaniline (PANI) conducting matrix to synthesize hybrid FeO/PANI binary nanocomposites (NCs) as modified MFC anodes via an in-situ polymerization process.

Lanthanum strontium ferrite (LaSrAgFeO = 0; LSFO) and its silver-doped derivative (LaSrAgFeO = 0.05; LASFO) are synthesized using mild conditions by a sol-gel method. Both oxides present a perovskite-like structure with orthorhombic symmetry due to octahedral tilting; thus, the incorporation of silver in the A-site does not significantly modify the perovskite structure.
