X-Ray Diffractometry
The crystallinity of PALNs synthesised was studied through the sharpness of peak in the XRD spectra by X’Pert3 Powder X-Ray Diffractometer with X’Celerator (Malvern Panalytical, UK). Samples used were lyophilised PALNs, pure ACV, and PM. Samples were radiated with CuK α radiation at 45 kV and 140 mA. 2θ scan range from 0° to 60°, with 3°/min scanning rate, and 0.05° step size were set (17). All the tests were performed in triplicates.
