“…[116] Yet, the nanoparticle formation is also obtained via self-assembly methodologies by exploiting ad-hoc modified alginate in which hydrophobic moieties are covalently appended onto the polymer backbone. [117,118] These amphiphilic macromolecules can self-assemble into NPs via intra-and/or intermolecular hydrophobic interactions and hydrogen bonding under appropriate stimulation. Self-assembled nanostructures usually present unique characteristics, including the high biocompatibility of native alginate, and they may allow the encapsulation of hydrophobic substances.…”

along with other polysaccharides (e.g., celluloses, chitosan, etc.), is indeed considered an extremely promising material in the viewpoint of circular economy and in substituting petroleum-derived polymers. [3] Among others, one of the reasons for alginate success is its unique capability to bind different cations leading to stable and tailor-made hydrogels. [4] Owing to its biocompatibility, biodegradability, and nontoxicity, in the past decades alginate has been vastly explored for drug and gene delivery, tissue engineering, and wound healing applications. [5] In this sense, the recent nanotechnological advances have allowed the fabrication and exploitation of alginate-based nanostructured materials with completely new capabilities. Thereby, it is not surprising that nowadays a broad variety of alginate-based nanomaterials with various shapes, sizes, and compositions are prepared via different approaches, including controlled gelation, electrospinning and electrospraying, self-assembly, phase-separation, and micro fluidics., All these nanostructures hold the potential to interact with living organisms much more efficiently with respect to bulk systems, hence leading to specific functionalities at the same time avoiding the occurrence of toxicity issues. [6][7][8] Despite the use of alginate-based nanomaterials has been reviewed in the past, the focus has been commonly pointed to their generic properties and applications. Conversely, this review attempts to provide a more specific and comprehensive summary limited to the most recent advances in the fabrication and use of two of the most common and promising alginatebased nanomaterials, namely nanoparticles (NPs) and electrospun nanofibers (NFs), with a focus on biomedical and pharmaceutical applications.

“…30 However, due to the intrinsic high hydrophilic nature of Alg particles, they fail to adhere at oil-water interfaces. Although several strategies [31][32][33][34] are currently available to reduce the hydrophilicity of Alg particles to stabilize oilin-water (O/W) Pickering emulsions, little progress has been made in applying them to obtain water-in-oil (W/O) Pickering emulsions.…”

A new kind of polymer surfactant, noncovalent binding between N,N‐dimethyl‐dodecylamine and alginate (C12A‐Alg), was successfully prepared by mixing N,N‐dimethyl‐dodecylamine (C12A) and sodium alginate (NaAlg) in the appropriate mole ratio and bubbling CO2. C12A was successfully grafted onto the alginate molecule by electrostatic interaction. The structure of C12A‐Alg was confirmed by Fourier transform infrared and NMR spectroscopies. The polymer surfactant C12A‐Alg has superior performance in foamability and emulsification. This foaming/defoaming and emulsification/demulsification behavior can be triggered by bubbling CO2/N2, demonstrating that the polymer surfactant C12A‐Alg is switchable. © 2018 Society of Chemical Industry
