Bacterial interactions of microplastics extracted from toothpaste under controlled conditions and the influence of seawater

Precise Tailoring of Polyester Bottlebrush Amphiphiles toward Eco‐Friendly Photonic Pigments via Interfacial Self‐Assembly

“…For comparison, non‐degradable PE microplastics could induce more than 40 % of growth inhibition towards the algae C. pyrenoidosa after 96 h exposure at 100 mg L −1 [15] . PE microplastics (100 mg L −1 , 36 h) also reduced the growth of E. coli by 15 % [16] . All these findings suggest that our photonic microspheres are much less toxic than the non‐degradable microplastics.…”

Visible-Light-Responsive Nanofibrous α-Fe2O3 Integrated FeOx Cluster-Templated Siliceous Microsheets for Rapid Catalytic Phenol Removal and Enhanced Antibacterial Activity

“…The bare 5FeSiO-MS was measured to have a higher zeta potential of −31.7 mV, which may lead to a more stable solution dispersion rather than the agglomeration. 45 The close attachment of particles to the bacteria cells is more favorable for the transport of reactive oxygen species, and the adsorption of a large number of catalysts can lead to the tear of cells and failure of ion exchange between cells and the external environment. 46 Moreover, Figure 10c further shows the optical images of the survived E. coli cells after cultured overnight following different treatments.…”

Caracterización de microplásticos en aguas naturales y residuales, y su influencia y separación en procesos biológicos de depuración

“…However, the extent of the interaction between nanoparticles and biocolloids (e.g., bacteria, virus, protozoa) will depend on several factors, including particles surface properties, such as zeta potential, and ionic strength of bulk solution (Fig. 5) (Ustabasi and Baysal, 2020).…”

“…Besides the ionic strength of the bulk solution, the zeta potential of NPs and bacteria plays a very important role in the interaction between NPs and bacteria (Pajerski et al, 2019;Ustabasi and Baysal, 2020). Zeta potential corresponds to the surface charge of nanoparticles and biocolloids and it is related to the electrostatic repulsion/attraction between them (Wang et al, 2015).…”

“…In addition, other factors, e.g. exposure time, the presence of additives, and shape and concentration of NPs, can also contribute to the toxicity of NPs on microorganisms (Lee et al, 2022;Sun et al, 2022;Ustabasi and Baysal, 2020). Furthermore, the degree of toxicity of NPs to microorganisms may be related to the type of monomer, presence of additives, and polymerization solvents .…”
