“…68 A system of cellulose powder, PEI, and crosslinked magnetic nanoparticles using glutaraldehyde has been used for preparing a crosslinked material. 156 Similarly, epichlorohydrin has been employed in a system of cellulose solution, PEI, and magnetic particles to create a crosslink between the cellulose and PEI. 179 The application of magnetic cellulose in devices like loudspeakers indeed is becoming a reality.…”

“…152 Independent of the type of magnetic particle, the removal of heavy metals or dyes from municipal and industrial wastewater is a challenge that has been solved in numerous prior studies. [153][154][155][156][157][158] Oil absorption and separation in general is one of the popular separation applications for magnetic cellulose. [159][160][161][162][163] The release of encapsulated substances has also been demonstrated using exposure to a magnetic field and for controlled delivery of drugs for cancer treatment.…”

Layered double hydroxides (LDHs) have received scientific attractions due to their unique two-dimensional (2D) structure, band gap tunability, and compositional flexibility, leading to the facile incorporation of the metal species into their layered structure. The main objective of this review is to explore the current advancement of LDH-based photocatalysts for photocatalytic hydrogen production by focusing on the role of divalent and trivalent metal incorporations and their efficiency enhancement. Firstly, the mechanism of photocatalysis and its thermodynamics has been explicated to gain basic understanding and fundamentals. Secondly, a brief introduction to the overview of LDH photocatalysts with special attention to the effects of cationic incorporations on the optical properties and computational study towards the electronic density has been demonstrated. Besides, the thermal stability of LDH is briefly discussed, focusing on the effects of temperature towards the conversion into mixed-metal oxide (MMO). Next, the classification of LDH based on divalent and trivalent cationic elements and their role in the brucite layer of LDH are systematically discussed. Attention is given to the mechanistic properties of the extensively studied metals, such as Mg, Ni, Zn, Co, Cr, Fe, V and Al, with the efficiency enhancements through various engineering aspects are demonstrated. The overview summary on the efficient design of LDH is elucidated to provide a deep understanding for improving their photocatalytic properties. Lastly, the future perspectives and recommendations are discussed to provide new insight into the potential of LDH and render them a notable place in solar energy applications.

“…In the case of polysaccharides, they have attracted the interest of many researchers in gene therapy due to their advantages, such as biocompatibility, biodegradability, low toxicity, and various modification strategies. Among the polysaccharides that have been used to carry out this modification are chitosan, cellulose, and natural gums [ 22 , 24 , 25 ]. Several strategies have been adopted to reduce polyethyleneimine (PEI) toxicity as the nucleic acid carrier [ 26 , 27 ].…”

Modification of Branched Polyethyleneimine Using Mesquite Gum for Its Improved Hemocompatibility

et al. 2021

In the present study, the modification of branched polyethyleneimine (b-PEI) was carried out using mesquite gum (MG) to improve its hemocompatibility to be used in biomedical applications. In the copolymer synthesis process (carboxymethylated mesquite gum grafted polyethyleneimine copolymer (CBX-MG-PEI), an MG carboxymethylation reaction was initially carried out (carboxymethylated mesquite gum (CBX-MG). Subsequently, the functionalization between CBX-MG and b-PEI was carried out using 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) and N-hydroxysuccinimide (NHS) as crosslinking agents. The synthesis products were characterized using Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), and thermogravimetric analysis (TGA). Thermogravimetric analysis showed that CBX-MG and CBX-MG-PEI presented a lower decomposition temperature than MG. The CBX-MG-PEI has a high buffer capacity in the pH range of 4 to 7, similar to the b-PEI. In addition, the CBX-MG-PEI showed an improvement in hemocompatibility in comparison with the b-PEI. The results showed a non-hemolytic property at doses lower than 0.1 µg/mL (CBX-MG-PEI). These results allow us to propose that this copolymer be used in transfection, polymeric nanoparticles, and biomaterials due to its physicochemical and hemocompatibility properties.
