Nanohole-boosted electron transport between nanomaterials and bacteria as a concept for nano–bio interactions

Nature Communications, Год журнала: 2021, Номер 12(1)

Опубликована: Янв. 21, 2021

Abstract Biofilms contribute to bacterial infection and drug resistance are a serious threat global human health. Antibacterial nanomaterials have attracted considerable attention, but the inhibition of biofilms remains major challenge. Herein, we propose nanohole-boosted electron transport (NBET) antibiofilm concept. Unlike known antibacterial mechanisms (e.g., reactive oxygen species production cell membrane damage), nanoholes with atomic vacancies serve as electronic donors receptors, respectively, thus boost high capacity between biofilms. Electron effectively destroys critical components (proteins, intercellularly adhered polysaccharides extracellular DNA) biofilms, also significantly downregulate expression genes related biofilm formation. The anti-infection is thoroughly verified both in vitro (human cells) vivo (rat ocular mouse intestinal models), nanohole-enabled found be highly biocompatible. Importantly, compared typical antibiotics, nonresistant thereby exhibit potential for use various applications. As proof-of-principle demonstration, these findings hold promise NBET treatments pathogenic antibiotic resistance.

Extracellular polymeric substances—antibiotics interaction in activated sludge: A review

Environmental Science and Ecotechnology, Год журнала: 2022, Номер 13, С. 100212 - 100212

Опубликована: Ноя. 9, 2022

Antibiotics, the most frequently prescribed drugs, have been widely applied to prevent or cure human and veterinary diseases undoubtedly led massive releases into sewer networks wastewater treatment systems, a hotspot where occurrence transformation of antibiotic resistance take place. Extracellular polymeric substances (EPS), biopolymers secreted via microbial activity, play an important role in cell adhesion, nutrient retention, toxicity resistance. However, potential roles sludge EPS related removal antibiotics are still unclear. This work summarizes composition physicochemical characteristics state-of-the-art EPS, highlights critical removal, evaluates their defense performances under different exposures, analyzes typical factors that could affect sorption biotransformation behavior antibiotics. Next, interactions between genes analyzed. Future perspectives, especially engineering application for detection defense, also emphatically stressed.

Microbial fuel cells and their electrified biofilms

Biofilm, Год журнала: 2021, Номер 3, С. 100057 - 100057

Опубликована: Сен. 20, 2021

Bioelectrochemical systems (BES) represent a wide range of different biofilm-based bioreactors that includes microbial fuel cells (MFCs), electrolysis (MECs) and desalination (MDCs). The first described bioelectrical bioreactor is the Microbial Fuel Cell with exception MDCs, it only type BES actually produces harvestable amounts electricity, rather than requiring an electrical input to function. For these reasons, this review article, previously unpublished supporting data, focusses primarily on MFCs. Of relevance architecture bioreactors, membrane they employ (if any) for separating chambers along size, as well geometry material composition electrodes which support biofilms. Finally, structure, properties growth rate biofilms colonising anodic electrodes, are critical importance rendering devices, functional living 'engines' applications.
