Preparation, identification and biological properties of new fluoride nanocompounds

2016, Dra. Gerli-Candia, Lorena, Lashgari, Amir, Ghamami, Shahriar, Golzani, Mojdeh, Salgado-Morán, Guillermo, Glossman-Mitnik, Daniel, Abdolmaleki, Behnaz

Nanoparticles (NPs) of new fluoride (SrF2 and MgF2) nanocompounds were synthesized by the simple chemical method of precipitation in ethanol. Synthesis of the strontium fluoride (SrF2)-magnesium oxide (MgO) nanocomposite was achieved through the ultrasonic method. These prepared nanopowders were characterized through Fourier transform infrared (FT-IR) spectroscopy, ultraviolet–visible (UV–Vis) spectroscopy, Powder X-ray Diffraction (PXRD) and Scanning Electron Microscopy (SEM). FT-IR confirmed the purity of the synthesized fluoride NPs by evaluation of the vibrations, and UV–Visible showed the intense absorption peaks of NPs. PXRD analysis indicated the average of particle size, and SEM demonstrated a nearly spherical morphology of the NPs. The antibacterical properties of the nanopowders on Staphylococcus Aureus, Bacillus Subtilis and E. Aklay bacteria were studied, with the strongest effect by the magnesium fluoride (MgF2) NPs and the SrF2-MgO nanocomposite.

Synthesis, chemical identification, drug release and docking studies of the Amlodipine–Chitosan nanobiopolymer composite

2021, Dra. Gerli-Candia, Lorena, Ramirez-Tagle, Rodrigo, Salgado-Moran, Guillermo, Mendez-Luna, David, Correa-Basurto, José, Cardona-Villada, Wilson, Mendoza-Huizar, Luis H.

A new amlodipine-chitosan nanocomposite was built using amlodipine nanoparticles as primary scaffolds by spontaneous emulsification, and its complete elucidation was performed by using several spectrometric techniques. Our results indicate that the amlodipine-chitosan nanocomposite has better solubility than amlodipine at pH 7.4 with a nearly all the drug substance dissolved (97%) by the final time-point measured. The docking study support the existence of intermolecular interactions are established between amlodipine and chitosan
