Aerobic Oxidation of Alcohols Catalyzed by Generated Gold Nanoparticles inside the Channels of Periodic Mesoporous Organosilica with Ionic Liquid Framework.

generated gold nanoparticles inside the nanospaces of periodic mesoporous organosilica with an imidazolium framework (Au@PMO-IL) were found to be highly active, selective, and reusable catalysts for the aerobic oxidation of activated and nonactivated alcohols under mild reaction conditions. The catalyst was characterized by nitrogen adsorption-desorption measurement, thermogravimetric analysis (TGA), transmission electron microscopy (TEM), elemental analysis (EA), diffuse reflectance infrared Fourier transform spectroscopy (DRIFT), X-ray photoelectron spectroscopy (XPS), and inductively coupled plasma atomic emission spectroscopy (ICP-AES). The catalyst exhibited excellent catalytic activity in the presence of either CsCO (35 °C) or KCO (60 °C) as reaction bases in toluene as a reaction solvent.

Enhanced antibacterial effect of azlocillin in conjugation with silver nanoparticles against .

In recent years, the problems associated with bacterial resistance to antibiotics caused nanodrugs to be considered as a new way for infectious diseases treatment. The main purpose of this study was to develop a new agent against a very difficult bacterium to treat, based on azlocillin antibiotic and silver nanoparticles (AgNPs). Azlocillin was conjugated with AgNPs by chemical methods and its antimicrobial activity was studied against .

Development of gentamicin-gold nanospheres for antimicrobial drug delivery to Staphylococcal infected foci.

Even though the therapeutic efficacy of numerous antimicrobial drugs has been well established, inefficient delivery can result in an inadequate therapeutic index. Gold nanoparticles have unique physicochemical properties such as large surface area to mass ratio and functionalizable structure. These properties can be applied to facilitate the administration of antimicrobial drugs, thereby overcoming some of the limitations in traditional antimicrobial therapeutics.
