Observation of synthesis and characterization of nanoparticles. A SEM scanning; B, C infrared light analysis; D SEM to observe the surface elements of nanoparticles; E–K X-ray photoelectron spectroscopy (XPS) measurement. L Particle size analyzer was used observing the particle size and stability distribution. M Particle size analyzer was used observing infrared spectroscopy analyzes the intensity and wavelength of particles. N Particle size analyzer was used observing siRNA loading rate. O Ultraviolet spectrophotometer was used to measure siRNA release rate
