“…For loading of clove oil, 1.5, 3.0, and 4.5 ml of oil was added to 50 ml of chitosan/carrageenan mixture with 0.5% Tween 20 as an emulsifier followed by ultrasonication at 30 kHz frequency with 50% amplitude and 25 • C, for 5 min. [17,18] A mixture solution with or without clove oil was dropped in an ethanolic solution of NaOH (1.0 M) with a 10 ml syringe from a distance of 15 cm. In this case, ethanol facilitates the solidification of beads which acts as non-solvent for chitosan, and the formed beads were separated through filtration and rinses with deionized water and dried at 30 • C under vacuum.…”

Background: Biopolymers are promising candidates that can be fabricated into hydrophilic matrices and used for many applications due to their distinctive properties such as non-toxic, biodegradable, biocompatibility, and low cost. A promising composite of chitosan and carrageenan with self-crosslinking has been prepared. Methods and Results:In this study, a rigorous approach for an inexpensive and nontoxic combination of different amounts of clove oil with two polyelectrolytes including chitosan and carrageenan in the form of beads has been prepared. The structure and the surface morphology of the beads were investigated using FTIR, X-ray diffraction (XRD), and SEM. Moreover, antimicrobial, antiviral activity, and molecular docking were evaluated. Antibacterial results revealed that chitosan/carrageenan@clove oil beads have antimicrobial activity as well as chitosan/carrageenan without clove oil against Escherichia coli AATCC25922, Pseudomonas aeruginosa AATCC27853, Staphylococcus aureus ATCC25923, Bacillus subtilis AATCC6051, and Candida albicans ATCC90028. Furthermore, maximum non-toxic concentration (MNTC) of chitosan/carrageenan@clove oil beads was (31.25 μg ml -1 ) which exhibited promising antiviral activity against Herpes simplex virus-1 (HSV-1), and was significantly higher than chitosan/carrageenan without clove oil, where antiviral activity was 82.94% and 57.64%, respectively. Eventually, docking study and computational calculation have been used to show the reactivity of the molecules. Conclusions:The developed chitosan/carrageenan@clove oil beads have shown promising properties to be used as carriers of drug delivery, tissue engineering, and regenerative medicine.

Smart polymeric matrices based on 2-vinyl pyridine (2-VPY) and three different crosslinkers: ethylene glycol dimethacrylate (EGDMA), divinylbenzene (DVB), and trimethylolpropane trimethacrylate (TMPTMA) were prepared either by the imprinting technique of the tramadol molecule or conventionally by the free radical polymerization process. The polymers were used as sorbent materials for tramadol from its solutions. The polymers prepared by the imprinting technique demonstrated superior absorption of tramadol molecules than those prepared by the conventional method. The two sorbent materials constructed from TMPTMA, regardless of the method, achieved the highest absorption capacity compared with those prepared from EGDMA or DVB. It was found that loaded imprinted polymer released more tramadol than loaded nonimprinted polymer in all media. In the acidic medium, the protonation of the nitrogen atom in the pyridine ring ionized the chains and expanded the loaded pores leading to the rapid release over the neutral and alkaline media. Additionally, the isothermal studies of MIP3 and NIP3 were extremely fitted to Freundlich adsorption and the (D-R) isotherm, respectively, while the kinetic studies of both sorbents were fitted to the pseudo-second-order model.

“…By this method aldehyde groups are introduced into polysaccharides and serve as useful material that can be used in different application such as adsorption of heavy metal, separation of protein and drug carriers, [7,17,18]. For a long time this process has used to produce dialdehyde cellulose, although it requires a long time [19,20].…”

Development of the oxidation process of cellulose has occurred to decrease the reaction time. Dialdehyd cellulose (DAC) has synthesized via periodate oxidation under microwave irradiation and Graphen oxide (GO) was synthesized by modified Hummer method. A new composite of DAC/GO has prepared from GO and DAC. The structure and morphology of DAC, GO and DAC/GO composite were evaluated via Fourier transform infrared spectroscopy, scanning electron microscopy and X-ray diffraction. Mechanical properties of DAC and DAC/GO were investigated. Additionally, the computational calculations of cellulose, DAC and GO by DFT/B3LYP/6-31G (d) basis sets were investigated. DAC/GO composite demonstrated specific antimicrobial activity against Gram-positive and Gram-negative bacteria. The molecular docking of DAC shows binding energy interaction (− 4.1, − 4.0, and − 4.0) Kcal/mol against microbial protein of Pseudomonas aeruginosa as Gram-negative bacteria PDB (2W7Q), and Staphylococcus aureus as Gram-positive bacteria PDB (1BQB) as well as Covid-19 PDB (7BZ5) respectively. DAC shows drug-like behavior when it is compared with binding energy interaction of Hydroxychloroquine against Covid-19, as a standard drug.
