Engineered nanomaterials may adversely impact human health and environmental safety by nano-bio-eco interactions not fully understood. Their interaction with biotic and abiotic environments are varied and complicated, ranging from individual species to entire ecosystems. Their behavior, transport, fate, and toxicological profiles in these interactions, addressed in a pioneering study, are subsequently seldom reported. Biological, chemical, and physical dimension properties, the so-called multidimensional characterization, determine interactions. Intermediate species generated in the dynamic process of nanomaterial transformation increase the complexity of assessing nanotoxicity. We review recent progress in understanding these interactions, discuss the challenges of the study, and suggest future research directions.

For the first time a novel fluorescent La@ZrMOF nanomaterial was synthesized for the convenient and visual detection of ethephon (ETH) based on the ligand-metal charge transfer process. The fluorescence signal gradually enhanced as the concentration of ETH increased, accompanied by a change in the color from colorless to blue. The assay can be completed within 75 min with a detection limit of 0.

Natural materials with highly oriented heterogeneous structures are often lightweight but strong, stiff but tough and durable. Such an integration of diverse incompatible mechanical properties is highly desired for man-made materials, especially weak hydrogels which are lack of high-precision structural design. Herein, we demonstrate the fabrication of hierarchically aligned heterogeneous hydrogels consisting of a compactly crosslinked sheath and an aligned porous core with alignments of nanofibrils at multi-scales by a sequential self-assembly assisted salting out method.

In this study, sustainable poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and pullulan (PUL)/PHBV filaments were prepared with ketoprofen for scaffold preparation. The research aimed evaluate the influence of pullulan in the filament properties, such as thermal, morphological, and biological behavior. Hansen parameters demonstrated the difference in the miscibility of the polymers and drug in the blend.

The development of an efficient coating with comprehensive antimicrobial and anticorrosion properties for metals is crucial. The present study used a one-pot strategy to fabricate a high-performance nanocomposite coating of carboxylated nitrile butadiene rubber/cellulose nanofibers/zinc oxide (XNBR/CNF-ZnO), demonstrating excellent potential for application in the protection against metal corrosion. Eco-friendly CNF-ZnO nanomaterials, prepared using the in-situ generation method, were used as reinforcing fillers, while XNBR was used as the matrix material.
