Functional and antimicrobial properties of herbal nanocomposites from Piper betle plant leaves for enhanced cotton fabrics

A structural and phase influences the physico‐chemical, in vitro bioactivity of alumina‐zirconia nanoparticles loaded chitosan‐sodium alginate scaffold for biomedical applications

“…The chitosan solution was slowly added to sodium alginate and stirred for 1 h to obtain a homogenous solution of chitosan-sodium alginate composite (hereafter named CSC). Biomimetic nanocomposite scaffolds were obtained by separately mixing three different concentrations (10,15, and 20 mg) of alumina-zirconia nanoparticles used as a filler material hereafter named, likewise, as sample (AZA1, AZA2, AZA3, AZT1, AZT2, AZT3) with chitosan-sodium alginate composite (CSC) and stirred for 24 h. Then, scaffolds were prepared by pouring the solution on sterile, dry Petri dishes and allowed for drying in a hot air oven at 80 C for 6 h.…”

“…The problem overcome by a surface modification of nanoparticles boosts biological activity. The especially outer surface of nanomaterials coated by biomaterials produces new physical characteristics with physiological reactions 10,11 …”

“…Their biocompatibility is evaluated by using MG-63 cells widely due to its use mostly characterized osteoblast cell lines and effective response toward various biomaterials. 1,5,8,12,14 In the present investigation, three concentrations of amorphous/ tetragonal alumina-zirconia nanoparticles (10,15, and 20 mg) were added with chitosan-sodium alginate solution and made biomimetic nanocomposite scaffolds by the solvent casting method. The physicochemical properties of synthesized amorphous/tetragonal aluminazirconia nanoparticles are characterized using XRD, DLS, SEM, FTIR, UV-visible, and photoluminescence spectroscopy.…”

“…The especially outer surface of nanomaterials coated by biomaterials produces new physical characteristics with physiological reactions. 10,11 Chitosan and sodium alginate are widely used biopolymers in biomedical and pharmaceuticals due to their superior physicochemical and biological characteristics. Above, the polymers combined and formed a polyelectrolyte complex (PEC) through ionic interaction between amines of chitosan and carboxyl groups of alginate.…”

Antibacterial activities against Staphylococcus aureus and Escherichia coli of extracted Piper betle leaf materials by disc diffusion assay and batch experiments

“…12,13 In particular, Piper betle (P. betle) is an interesting choice for an antibacterial agent for both bacteria types because its leaf has active chemical compounds such as phenols, alkaloids, carbohydrates, avonoids, chavibetol, and eugenol. [14][15][16][17] Therefore, this study attempted to extract P. betle from powdered P. betle leaf, and then modify the extracted P. betle to a bead form as a novel antibacterial material from the applied engineering aspect. Moreover, their antibacterial efficiencies on S. aureus and E. coli were investigated through a series of batch experiments for possible disinfectant applications in wastewater treatment.…”
