Facile and green synthesis of highly stable l-cysteine functionalized copper nanoparticles
چکیده انگلیسی
A simple eco-friendly method for l-cysteine capped copper nanoparticles (CCNPs) synthesis in aqueous solution has been developed. Glucose and l-cysteine were used as reducing agent and capping/functionalizing agent, respectively. Different parameters such as capping agent concentration, pH, reaction temperature, and reducing agent concentration were optimized during the synthesis. The l-cysteine capped copper nanoparticle were characterized by ultraviolet-visible spectroscopy, Fourier-transform infrared spectroscopy, X-ray diffraction, Particle size and zeta potential analyser, and high resolution transmission electron microscopy. Spherical shaped cysteine functionalized/capped copper nanoparticles with an average size of 40 nm were found to be highly stable at room temperature (RT) for a period of 1 month
