This study introduces a hydrophobically modified bacterial cellulose nanofibrils (BCNF)-stabilized Pickering emulsion system, which can limit the influx of metal ions through the interface. We showed that the C18 alkyl chain-grafted BCNF (BCNF) can readily associate to generate a resilient thin membrane at the oil-water interface regardless of the type of oil, which is essential for the production of stable emulsion drops. The viscoelasticity of BCNF-armored Pickering emulsion was feasibly tunable by manipulating the grafting amount of the C18 alkyl chains, as well as controlling the BCNF concentration. We also demonstrated that the BCNF membrane formed at the interface effectively entrapped metal ions through electrostatic binding with the carboxyl groups on BCNF, thus maintaining original UV-absorbing capability of chemical UV filter-containing emulsions. We expect that the BCNF surfactant fabricated in this study has immense potential for the development of various complex emulsion products.

Industrial wastewater containing heavy metal ions presents serious economic risk to the environment. In this study, a novel compound of aminated cellulose with jeffamine EDR148 was prepared to improve cellulose's adsorptive behavior towards metal ions. This study undertook a straightforward and efficient cellulose modification through homogeneous chlorination in N,N'-butylmethylimidazolium chloride to produce 6-deoxychlorocellulose (Cell-Cl), followed by a reaction with jeffamine EDR148 and ultimately resulting in the formation of aminated cellulose (Cell-Jef148).

Antimicrobial polymeric coatings rely not only on their surface functionalities but also on nanoparticles (NPs). Antimicrobial coatings gain their properties from the addition of NPs into a polymeric matrix. NPs that have been used include metal-based NPs, metal oxide NPs, carbon-based nanomaterials, and organic NPs.

As a structural and catalytic cofactor, copper is involved in many biological pathways and is required for the biochemistry of all living organisms. However, excess intracellular copper can induce cell death due to its potential to catalyze the generation of reactive oxygen species, thus copper homeostasis is strictly regulated. And the deficiency or accumulation of intracellular copper is connected with various pathological conditions.

Spontaneous cleavage reactions normally occur in vivo on amino acid peptide backbones, leading to fragmentation products that can have different physiological roles and toxicity, particularly when the substrate of the hydrolytic processes are neuronal peptides and proteins highly related to neurodegeneration. We report a hydrolytic study performed with the HPLC-MS technique at different temperatures (4 °C and 37 °C) on peptide fragments of different neuronal proteins (amyloid-β, tau, and α-synuclein) in physiological conditions in the presence of Cu and Zn ions, two metal ions found at millimolar concentrations in amyloid plaques. The coordination of these metal ions with these peptides significantly protects their backbones toward hydrolytic degradation, preserving the entire sequences over two weeks in solution, while the free peptides in the same buffer are fully fragmented after the same or even shorter incubation period.
