“…Acid neutralization and solvent shifting have been the most frequent routes adopted to prepare LNPs, acidification being the first reported method. Several recent review articles reveal the existence of many other approaches, such as acid-catalyzed precipitation, flash precipitation, water-in-oil microemulsion methods, homogenization, ultrasonication, and sono-solvent shifting. ,− Among the developed LNP fabrication methods, the critical analysis points to the solvent shifting approach as the method of choice due to its simplicity, viability, high yield, and excellent control over morphological features in terms of spherical geometry, with uniform size and smooth surfaces. Hence we focus mostly on that method in the following section.…”

This review presents recent advances regarding biomass-based nanomaterials, focusing on their surface interactions. Plant biomass-based nanoparticles, like nanocellulose and lignin from industry side streams, hold great potential for the development of lightweight, functional, biodegradable, or recyclable material solutions for a sustainable circular bioeconomy. However, to obtain optimal properties of the nanoparticles and materials made thereof, it is crucial to control the interactions both during particle production and in applications. Herein we focus on the current understanding of these interactions. Solvent interactions during particle formation and production, as well as interactions with water, polymers, cells and other components in applications, are addressed. We concentrate on cellulose and lignin nanomaterials and their combination. We demonstrate how the surface chemistry of the nanomaterials affects these interactions and how excellent performance is only achieved when the interactions are controlled. We furthermore introduce suitable methods for probing interactions with nanomaterials, describe their advantages and challenges, and introduce some less commonly used methods and discuss their possible applications to gain a deeper understanding of the interfacial chemistry of biobased nanomaterials. Finally, some gaps in current understanding and interesting emerging research lines are identified.

“…Lignin is generated ∼70 million tons per year from different lignocellulosic biomass-utilizing industries . Owing to its high heating value, lignin has been used as a fuel source, but a vast quantity of lignin is not effectively utilized due to unknown knowledge about the full potential of lignin. , Lignin structural and chemical properties depend on its source and extraction methodologies . Also, these diverse types of lignin exhibit dissimilar deviations in molecular weight, elemental composition, and functional groups.…”

Searching for sustainable, ecofriendly, and renewable precursors for nanostructured material synthesis is a fascinating area pertaining to feasibility in various applications. Especially, lignin-based material preparation is essential for unraveling the usage of lignin by valorization. Hence, we have synthesized lignin nanoparticles (LNPs) using date palm tree ( Phoenix dactylifera L. ) biomass as a precursor in this investigation. The LNP’s morphological and thermal features were assessed. Moreover, we have evaluated the LNP’s cytocompatibility properties by adopting in vitro approach. The P. dactylifera L. (PD) biomass-derived LNP’s morphological features show a spherical shape with a 10–100 nm diameter. The LNPs have a decreased cell viability of ∼8% at a high concentration exposure to human mesenchymal stem cells (hMSCs) for 48 h. However, the LNPs do not cause any cellular and nuclear morphology changes in hMSCs. The mitochondrial membrane potential assessment results confirm healthy mitochondria with high mitochondrial membrane potential in LNP-treated cells. The intracellular reactive oxygen species (ROS) generation assay results revealed that LNPs do not trigger ROS generation in hMSCs. We examined the upregulation of GSTM3 and GSR genes and the downregulation of SOD1 genes in LNP-treated hMSCs, but no significant changes were observed. Our study concluded that PD biomass-derived LNPs have a good cytocompatibility and an antioxidant property. Thus, they can be applicable for various biological, cosmetic, and environmental applications.

“…In fact, the use of lignin as a catalytic converter can demonstrate great technological opportunities and promote a cleaner environment by using a sustainable feedstock instead of classic metal, acid, or base catalysts (Pd, Pt, Ni, Cu, Co, Ru, KOH, NaOH, H 2 SO 4 , etc.). 41,54,123,124 Given its rich surface functional groups, lignin can be used as a suitable precursor for the preparation of innovative, ecofriendly and energyefficient catalysts with outstanding reuse benefits.…”
