Plant-derived synthesis of iron oxide nanoparticles for magnetic hyperthermia and magnetic resonance imaging applications
Get PDFThe biomedical applications of iron oxide nanoparticles (IONPs) synthesized using environmentally friendly processes are extremely promising. Using eco-friendly and nontoxic methods is a safer alternative to conventional chemical synthesis, which generates toxic byproducts. It allows for greater control over particle size and morphology. The resulting unique magnetic and optical properties of IONPs enable their use in biomedical applications such as magnetic hyperthermia (MH) and magnetic resonance imaging (MRI). This review aimed to summarize recent advances in the synthesis, characterization, and biosafety of IONPs for use in MH and MRI. It also aimed to highlight the significance of eco-friendly synthesis techniques for producing IONPs with the desired magnetic and physicochemical properties. Overall, this review elucidated the most efficient methods for utilizing iron oxide while considering biocompatibility

Physical parameters optimization of bacterial cellulose from Komagataeibacter sucrofermentans
Get PDFMany studies have been concerned with nanocellulose's potential to produce environmentally friendly nanomaterial fibers. Bacterial cellulose has shown superiority over plant cellulose, leading to increased research focus on bacterial cellulose production. Among bacterial species, Acetobacter, particularly Komagataeibacter (formerly Gluconacetobacter), has captured interest due to its enhanced bacterial cellulose (BC) production and strain stability. Optimizing production processes becomes imperative with the growing demand for BC in various industries. This study explores the optimization of physical conditions for BC production using Komagataeibacter sucrofermentans. Five parameters—pH, temperature, aeration rate, shaking rate, and surface area, were examined using the One-factor-at-a-time (OFAT) method. This method was selected as it is useful in early-stage optimization to understand the effect of individual factors on BC production. The extracted BC was purified with 4.0 M NaOH solution at 80°C, and wet and dry weights were measured. Analysis via ANOVA determined the significance of each parameter in enhancing BC yield. Optimized conditions from this experiment —pH 5, temperature 20°C, 60% aeration rate, slow agitation (50 rpm), and large surface area fermentation (63.62 cm2) shown to give better BC production. These findings have substantial implications for enhancing BC production efficiency on an industrial scale
