“…This is much higher than the adsorption capacity previously reported for the adsorbent, 11 times that of Co‐MOF (148 mg/g), [28] and 3 times that of activated carbon (580 mg/g) [29] and GO (570.4 mg/g) [30] . Even the adsorption performance of AMSA is nearly 2.4 times higher than that of calcium ion cross‐linked sodium alginate composite (SA/PPyNT composite microbeads, 666.7 mg/g) [31] . This has proven that AMSA, which is simple to synthesize, rich in source, easy to separate and does not produce secondary pollution, is a potential candidate for efficient and rapid removal of MB.…”

The acid-modified sodium alginate (AMSA) was synthesized utilizing a simple acidification method and its synthesis was confirmed by acid-base titration method, SEM, XRD, FTIR, TGA and BET. The sodium alginate after acidification, with a large number of carboxyl groups introduced, was favorable to the adsorption of methylene blue (MB) from water. The maximum adsorption capacity calculated by Langmuir model was up to 1593 mg/g, which was significantly higher than the adsorption capacity of other adsorbents reported. The adsorption rate of MB by AMSA was very fast. After the addition of adsorbent, the adsorption removal rate reached 79 % in 30 min, and the adsorption was balanced in 120 min (94 % of MB was removed). Furthermore, electrostatic interaction and hydrogen bonding, pore-filling and chemisorption were considered as the main adsorption mechanisms. AMSA is expected to be an optimal candidate for efficient and rapid removal of MB due to its simple synthesis, abundant sources, easy separation and no secondary pollution.

“…Due to their relatively inexpensiveness and good removal efficiency of dyes, alginate nanocomposites have received increasing attention in recent years. Since natural alginates have a significant number of functional groups on the surface, they can easily adsorb both the anionic and the cationic dyes from wastewaters, as well as from both acidic and basic media ( Heybet et al, 2021 ). On the other hand, adding other nanomaterials, such as GO or carbon nanotubes, is one of the most effective methods to improve the adsorption capacity of alginate-based nanomaterials ( Zhuang et al, 2016 ; Khan et al, 2021 ).…”

Since the ancient times, bee products (i.e., honey, propolis, pollen, bee venom, bee bread, and royal jelly) have been considered as natural remedies with therapeutic effects against a number of diseases. The therapeutic pleiotropy of bee products is due to their diverse composition and chemical properties, which is independent on the bee species. This has encouraged researchers to extensively study the therapeutic potentials of these products, especially honey. On the other hand, amid the unprecedented growth in nanotechnology research and applications, nanomaterials with various characteristics have been utilized to improve the therapeutic efficiency of these products. Towards keeping the bee products as natural and non-toxic therapeutics, the green synthesis of nanocarriers loaded with these products or their extracts has received a special attention. Alginate is a naturally produced biopolymer derived from brown algae, the desirable properties of which include biodegradability, biocompatibility, non-toxicity and non-immunogenicity. This review presents an overview of alginates, including their properties, nanoformulations, and pharmaceutical applications, placing a particular emphasis on their applications for the enhancement of the therapeutic effects of bee products. Despite the paucity of studies on fabrication of alginate-based nanomaterials loaded with bee products or their extracts, recent advances in the area of utilizing alginate-based nanomaterials and other types of materials to enhance the therapeutic potentials of bee products are summarized in this work. As the most widespread and well-studied bee products, honey and propolis have garnered a special interest; combining them with alginate-based nanomaterials has led to promising findings, especially for wound healing and skin tissue engineering. Furthermore, future directions are proposed and discussed to encourage researchers to develop alginate-based stingless bee product nanomedicines, and to help in selecting suitable methods for devising nanoformulations based on multi-criteria decision making models. Also, the commercialization prospects of nanocomposites based on alginates and bee products are discussed. In conclusion, preserving original characteristics of the bee products is a critical challenge in developing nano-carrier systems. Alginate-based nanomaterials are well suited for this task because they can be fabricated without the use of harsh conditions, such as shear force and freeze-drying, which are often used for other nano-carriers. Further, conjunction of alginates with natural polymers such as honey does not only combine the medicinal properties of alginates and honey, but it could also enhance the mechanical properties and cell adhesion capacity of alginates.

Water pollution by organic dyes, and its remediation, is an important environmental issue associated with ever-increasing scientific interest. Conducting polymers have recently come to the forefront as advanced agents for removing dye. The present review reports on the progress represented by the literature published in 2020–2022 on the application of conducting polymers and their composites in the removal of dyes from aqueous media. Two composites, incorporating the most important polymers, polyaniline, and polypyrrole, have been used as efficient dye adsorbents or photocatalysts of dye decomposition. The recent application trends are outlined, and future uses also exploiting the electrical and electrochemical properties of conducting polymers are offered.
