In order to handle urgent energy and environmental issues, the development of a circular economy supported by lignocellulosic biorefineries is essential right now. In this respect, lignin should no longer be seen as a waste or byproduct but as a renewable and abundant resource. This is why research has recently focused on the development of lignin nanoparticles (LNPs) from kraft lignin (KL), opening up new value-added areas. However, to date, no study has focused on a top-down lignin-based approach over further produced LNP properties, i.e., the contribution of the initial raw biomass types (hardwood, softwood, and herbaceous material) and lignin macroparticle extraction. This top-down, lignin-based approach, considering lignin valorization as the primary resource from the design phase, offers insights into the chemical lignin structure and functional group interactions in LNP formation. To this end, a new water steam explosion pretreatment was carried out upstream of an ethanol-organosolv treatment in order to rapidly extract pure lignin, which is then reduced to nanosize by antisolvent precipitation. We show that the initial raw biomass type such as lignin extraction (organosolv lignin compared to KL) makes a significant difference to particle size (50−250 nm), aggregation, and morphology in aqueous suspensions. The tailored LNPs formed by this eco-friendly, simple, fast, and high-yield process (7−15 wt % LNPs of initial biomass byproducts), which can be upscaled for industrial purposes, are stable over 90 days' storage and have better properties than those of kraft LNPs. LNPs resulting from this work therefore have great potential for high value-added applications such as cosmetics and medicine.

Bacterial diseases are causing major health issues across the world. Recent research has revealed that the metal ion discharge of nanomaterials is extremely effective at eradicating bacterial outbreaks and resistance. Reactive oxygen species (ROS) for antibacterial functions have been produced using nanomaterials with high specific surface area, complex structural framework, and spectral properties. In this study, we thoroughly investigated the impact of Zn dopants on copper oxide (CuO) nanostructures and their nanomaterial‐based antibacterial processes. The method of production includes the formation of CuO and Zn‐doped CuO nanostructures via chemical coprecipitation. By using several characterization techniques, the as‐synthesized nanostructures were confirmed. Based on their specific surface area and surface‐active site, the different antibacterial activities of these dopants vary the antibacterial action. The antibacterial activity was evaluated using the agar well diffusion method. A significant antibacterial action was observed in the samples. In the pharmaceutical and food sectors, this CuO and its combined dopants can be a substitute for synthetic antibacterial agents.

“…Therefore, we aimed to develop a preanalytical strategy that provides an improvement toward enabling the in-field application of nanobiosensors, in line with recent literature addressing the challenges this technology faces on the road to market [ 53 ]. To the best of our knowledge, this is the first time a methodology is specifically reported to enable the detection of AFB1 from cattle feed directly in the crude extract.…”

Aflatoxin contamination of cattle feed is responsible for serious adverse effects on animal and human health. A number of approaches have been reported to determine aflatoxin B1 (AFB1) in a variety of feed samples using aptasensors. However, rapid analysis of AFB1 in these matrices remains to be addressed in light of the complexity of the preanalytical process. Herein we describe an optimization on the preanalytical stage to minimize the sample processing steps required to perform semi-quantitative colorimetric detection of AFB1 in cattle feed using a gold nanoparticle-based aptasensor (nano-aptasensor). The optical behavior of the nano-aptasensor was characterized in different organics solvents, with acetonitrile showing the least interference on the activity of the nan-aptasensor. This solvent was selected as the extractant agent for AFB1-containing feed, allowing for the first time, direct colorimetric detection from the crude extract (detection limit of 5 µg/kg). Overall, these results lend support to the application of this technology for the on-site detection of AFB1 in the dairy sector.
