Abstract Unlike growth on tissue, microbes can grow freely implantable devices with minimal immune system intervention and often form resilient biofilms that continuously pump out pathogenic cells. The efficacy of antibiotics used to treat infection is declining due increased rates resistance. A simple, one‐step zwitterionic surface modification developed significantly reduce protein microbial adhesion synthetic materials demonstrate the successful several clinically relevant materials,...
1,4-Dioxane is one of the most frequently detected organic water contaminants and often co-occurs with chlorinated volatile compounds due to its use as solvent stabilizer. Its recalcitrance challenges natural attenuation processes conventional treatment technologies. Here, we examined bioelectrochemical oxidation 1,4-dioxane using dimensionally stable mesh electrodes in flow-through reactors coupled bioaugmentation by Pseudonocardia dioxanivorans CB1190. influent concentrations were rapidly...
Chitosan hydrogels have widespread industrial applications due to their versatility and antimicrobial potential. However, applicability can be limited by poor mechanical properties or because fabrication requires the use of toxic compounds which leach into environment. Additionally, water solubility under neutral conditions restricts low pHs. Here, we synthesized a modified derivative [N-(2-hydroxy-3-trimethylammonium)propyl] chitosan chloride (HTCC), is soluble at pH, used it compare effect...
Biofilms are a leading cause of infections, especially those initiated on medical tubing. Quantification pathogenic biofilms is critical for systematic determination antibiotics prescription, and implant replacement. By the time infectious pathogens detected in fluids such as blood or urine, substantial potentially life-threatening likely to have already formed. These can broad ranging patient care cost implications. Here we propose non-strain-specific protocol combining four microbiological...
Antibiofouling Harmful microbes can grow freely on implanted medical devices such as catheters (as shown the right). In article number 2200254, Amir Sheikhi, Richard B. Kaner, and co-workers, report a new method to apply robust surface coating containing zwitterions, which creates water layer that prevents biofilm formation left). This improve safety of reduce patient complications. Image credit: Sheikhi/Penn State.
Efficient removal of heavy metal pollutants from stormwater by ion-exchange sorbents requires knowledge and understanding adsorption patterns. The present study elucidates the characteristics six toxic cations (Cd2+, Cr3+, Cu2+, Ni2+, Pb2+, Zn2+) a natural (clinoptilolite) two synthetic (13X 4A) zeolites. Adsorption kinetics equilibrium isotherms have been obtained. An order magnitude lower efficiency was obtained with clinoptilolite relative to one zeolites 13X 4A. As in many other studies,...
