TLDR
The ability of CuO nanoparticles to reduce bacterial populations to zero was enhanced in the presence of sub-MBC concentrations of silver nanoparticles, suggesting release of ions may be required for optimum killing.About:

Synthesis and characterization of lipophilic bismuth dimercaptopropanol nanoparticles and their effects on oral microorganisms growth and biofilm formation
Appala Raju Badireddy,Rene Hernandez-Delgadillo,Rosa Isela Sanchez-Najera,Shankararaman Chellam,Claudio Cabral-Romero +4 more
TL;DR: Findings show the efficacy of bismuth dimercaptopropanol nanoparticles (BisBAL NPs) as a broad spectrum antimicrobial agent which could reduce antibiotic usage, and hypothesize that they potentially act on key enzymes, altering their metabolism, and cause cell lysis.
Journal ArticleDOI
Differential surface contact killing of pristine and low EPS Pseudomonas aeruginosa with Aloe vera capped hematite (α-Fe2O3) nanoparticles.
TL;DR: The results elucidate that ALE-α-Fe2O3NPs-bacterial interaction leads to attachment of NPs to EPS surface, migration within the EPS matrix and penetration into cell, which eventually results in growth inhibition due to intracellular ROS activity.

Antimicrobial Properties of Electrically Formed Elastomeric Polyurethane–Copper Oxide Nanocomposites for Medical and Dental Applications
Zeeshan Ahmad,M. A. Vargas-Reus,Raheleh Bakhshi,F. Ryan,Guogang Ren,Faik N. Oktar,Robert P. Allaker +6 more
TL;DR: This approach demonstrates the potential of generating tailored antimicrobial structures for a host of applications, such as designer filters, patterned coatings, breathable fabrics, adhesive films (as opposed to sutures), and mechanically supporting structures.

Components from wheat roots modify the bioactivity of ZnO and CuO nanoparticles in a soil bacterium.
TL;DR: It is deduced that the response of a microbe to these metal oxide NPs could be negated by components released from roots, and root wash components did not protect culturability or biosensor light output upon exposure to Cu ions.
Journal ArticleDOI
Dynamics of sub-lethal effects of nano-CuO on the microalga Chlamydomonas reinhardtii during short-term exposure.
TL;DR: The results suggest that agglomerated nano-CuO is toxic and that exposure media are decisive in whether or not particles or free Cu ions are the main mediators of toxicity.

The bactericidal effect of silver nanoparticles
Jose Ruben Morones,Jose Luis Elechiguerra,A. Camacho,Katherine B. Holt,Juan B. Kouri,Jose Tapia Ramirez,Miguel Jose Yacaman +6 more
TL;DR: The results indicate that the bactericidal properties of the nanoparticles are size dependent, since the only nanoparticles that present a direct interaction with the bacteria preferentially have a diameter of approximately 1-10 nm.

Silver nanoparticles as antimicrobial agent: a case study on E. coli as a model for Gram-negative bacteria
Ivan Sondi,Branka Salopek-Sondi +1 more
TL;DR: These nontoxic nanomaterials, which can be prepared in a simple and cost-effective manner, may be suitable for the formulation of new types of bactericidal materials.

Evidence for stripe correlations of spins and holes in copper oxide superconductors
TL;DR: In this article, the authors examined the possibility that this effect is related to dynamical two-dimensional spin correlations, incommensurate with the crystal lattice, that have been observed in La2-SrxCuO4 by neutron scattering.

Metal Oxide Nanoparticles as Bactericidal Agents
TL;DR: In this paper, reactive magnesium oxide nanoparticles and halogen (Cl2, Br2) adducts of these MgO particles were allowed to contact certain bacteria and spore cells, which yield insight into the biocidal action of these nanoscale materials.
