Dinesh Kumar Different concentrations (2, 4, 6, and 8 mole %) of cobalt doped cerium oxide nanoparticles (CeO2:Co NPs) were synthesized by hydrothermal method. The synthesized samples were characterized by using various techniques to understand their structural, optical and surface morphological properties. The face-centred cubic (FCC) structure of the CeO2:Co NPs was identified from the X-ray diffraction (XRD) analysis. The calculated crystallit...

Sieroń In situ forming implants (ISFI) are proved to be effective drug delivery systems in various local therapies. This research focuses on preliminary characteristics of a new biodegradable ISFI formulation based on poly(isosorbide succinate) (PISU) for modulated, over 3-week, release of doxycycline hyclate (DOXY). The Alamar Blue cytotoxicity assay was carried out for PISU using FK-1 and AoSMC cell lines. PISU...

Silver nanoparticles (SNPs) were synthesised by using the Arial part extract of Dorema ammoniacum D. and characterised by employing UV–visible spectroscopy, Fourier transform infrared spectroscopy and X-ray diffraction techniques. Transmission electron microscopy and field emission scanning electron microscopy were applied to investigate the morphological structure of the bio-synthesised SNPs. The antimicrobial activity of SNPs was studied against Gram positive (Bacillus cereus and Staphylococcus aureus) and Gram-negative (Escherichia coli and Salmonella typhimurium) bacteria by employing the disk diffusion agar proc...

Authors: Aksakal B, Demirel M, Sinirlioglu ZA Abstract Hydroxyapatite (HA)-based biografts with selenium (Se) and silver (Ag) substitutions were synthesized using the sol-gel method. The synthesized HA-based biografts at various Se and Ag quantity ratios (wt%) were characterized via Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and energy dispersive X-Ray spectroscopy (EDX). Escherichia coli (JM103) and Gram-positive Staphylococcus aureus (ATCC29293) bacteria were used for the cell viability tests by performing the MTT assay. During antibacterial tests, it was determined that th...

This study aimed to characterize the structural and physico-mechanical properties of bacterial cellulose (BC) produced by Gluconoacetobacter xylinus TJU-S8 which was isolated from Chinese persimmon vinegar. Thermogravimetric analysis (TGA) showed that BC exhibited a good thermal stability. Solid-state nuclear magnetic resonance (NMR), fourier transform infrared spectroscopy (FT-IR) and x-ray diffraction (XRD) analysis revealed that BC had a typical crystalline form of the cellulose I. The BC membrane had typical characteristics such as nanodimensional network and microfibrils obtained by scanning electron microscopy (SEM)....

We report the development of effective drug loaded nanocarriers to combat multidrug resistant infection especially in case of osteomyelitis. The hollow mesoporous hydroxyapatite nanoparticles (hmHANPs) and solid/non-hollow hydroxyapatite nanoparticles (sHANPs) were synthesized by core–shell and co-precipitation techniques respectively. High encapsulation of the drug (ciprofloxacin) was observed in hmHANPs as compared to sHANPs, which may be due to the hollow porous structure of hmHANPs. These nanoparticles were characterized by scanning electron microscope (FESEM), N2 adsorption/desorption, Fourier transform infrared...
