Summary: In this study, chitosan was used to encapsulate the mycelia of the white-rot fungus and form chitosan fungal beads for multiple extractions and nanoparticle synthesis. The resulting nanoparticles were composed of chitosan-silver nanoparticles with a size of 25 nm. The chitosan fungal beads lost their ability to produce chitosan-silver nanoparticles after three extractions and nanoparticle synthesis.

Summary: This study evaluated the effects of cisplatin and a plant extract alpha-mangostin on ovarian cancer cells and the cancer cell microenvironment. The results showed that the combination of alpha-mangostin and cisplatin reduced the concentration of cisplatin while maintaining the same cytotoxic effect. Additionally, the composition of exosomes released from drug-treated cancer cells may be different from untreated cells.

Summary: The hypothesis of this study is that silver nanoparticles coated with organic-inorganic hybrid silica or inorganic silica have antimicrobial ability and the coating can effectively improve the dispersion and stability of the particles. The slow release of silver ions (Ag+) can enhance the antimicrobial activity of the nanoparticles. The experiments confirmed that both types of silver-based nanoparticles had uniform size, good stability, and showed antimicrobial properties against Aspergillus niger and Penicillium citrinum.

Summary: Gold nanoparticles (AuNPs) offer unique physicochemical properties for the development of novel biomedical technologies, with the ability to be functionalized through the immobilization of biomolecules for various purposes. The interaction between proteins and AuNPs involves electrostatic bridging, leading to reversible aggregation within the first few hours and irreversible aggregation after 24 hours. This study provides insights into antibody-nanoparticle interactions and suggests a method to prevent protein-induced AuNP aggregation over a wide pH range.

Summary: In this research, silver nanoparticles (AgNPs) were synthesized using various chitosan salts as stabilizing agents, which effectively prevented nanoparticle aggregation. Different chitosan salts were formed using organic acids such as acetic, succinic, formic, propionic, malic, glycolic, and lactic acid, providing a sustainable and economical method for AgNPs synthesis. Characterization techniques including UV-VIS, ATR-FTIR spectroscopy, DLS, and TEM were used to analyze the AgNPs-chitosan salts samples. Most organic acids resulted in small-sized nanoparticles (30-52 nm) with positive zeta potential. However, the use of salts of alpha-hydroxyacids and diacids, such as glycolate and succinate, led to larger particles. Stability studies revealed that storage at cold temperatures enhanced the stability of the silver nanoparticles.

Summary: The colloidal stability and controlled assembly of functional colloidal nanoparticles are two major aspects. This study reveals the relationship between the ligand shell structures, interparticle interactions, and dynamical behaviors of small-sized nanoparticles capped with hydrocarbon chain ligands, and discovers a transformation of interparticle interactions from anisotropic attractions to isotropic repulsions caused by the change in ligand shell structures.

Summary: The study revealed that AgNPs and AuNPs have damaging effects on the DNA of tobacco plants, with significant DNA damage observed at a concentration of 30 mg.kg(-1) of AgNPs but no significant effect from AuNPs. The silver content in leaves at a concentration of 30 mg.kg(-1) of AgNPs was determined to be approximately 2.720 μg.g(-1). Long-term effects were found to be less harmful, possibly due to the plant's restoration capability.

Summary: In recent decades, there has been a growing interest in conducting polymers for their broad applications. However, the techniques for producing 2D nanosheets of conducting polymers are either complex or expensive, and a comprehensive approach for constructing 2D and 3D materials or their composites has not been documented. In this study, a simple and scalable synthetic protocol was developed to design 2D, 3D, and related conducting polymer nanocomposites. Diverse bicontinuous thin layers of oil and water were used to produce 2D nanosheets, and specially designed linkers were applied to lock the 3D networks of the conducting polymers and their composites. This technique is cost-effective and easily scalable, and it achieved the highest reported electrical conductivity for 2D PPY nanosheets to date.

Summary: The aim of this study was to extract and characterize silica materials from various agro-industrial wastes including sugarcane bagasse, corn stalk, and rice husk. The results showed that silica yields of 17.91%, 9.39%, and 3.25% were obtained for RH, CS, and SCB, respectively. The textural properties indicated that the siliceous materials had mesoporous structures, with SCB and CS forming crystalline SiO2 and RH forming amorphous. XPS spectra demonstrated the presence of Si4+ species in RH, and Si3+/Si4+ tetrahedra in SCB and CS.
