All chemicals used in this experiment were of analytical grade and purchased from local suppliers. Analytical grade compounds of zinc (II) nitrate [Zn (NO3)2.6H2O], and sodium hydroxide were obtained from Merck. Commercial ZnO-NPs (US3580, NanoSany, Iran) (35–45 nm, 99% purity, spherical shape) were purchased from NanoSany, Iran. The fresh plant materials were obtained from local traders (Ardabil, Iran) and further identified by a botanist.

All chemicals were of analytical grade and used without further purification. Losartan, potassium salt was purchased from Parafarm and Zinc(II) nitrate (Merck) was used as supplied. A sodium silicate solution (14% NaOH-27% SiO 2 , SiO 2 .NaOH, Sigma-Aldrich) was used for the diffusion method. Infrared spectra of powdered samples were measured with a Bruker IFS 66 FTIR-spectrophotometer from 4000 to 400 cm -1 using the KBr pellet technique. FT-Raman spectra were measured using the FRA 106 Raman accessory with germanium detector operating at liquid nitrogen temperature. A continuouswave Nd/YAG laser working at 1064 nm was employed for Raman excitation. Elemental analyses for carbon, hydrogen and nitrogen were performed using a Carlo Erba EA 1108 analyzer. Thermogravimetric analysis (TGA) were measured with a Shimadzu system (model TG-50), working in an oxygen flow of 50 mL/min and at a heating rate of 10 °C/min. Sample quantities ranged between 5 and 10 mg. Electronic absorption spectra were recorded on a Hewlett-Packard 8453 diode-array spectrophotometer, using 1-cm quartz cells. Fluorescence spectra were measured using a Shimadzu RF-6000 spectrophotometer. The molar conductance of the complex was measured on a Conductivity TDS Probe -850,084, Sper Scientific Direct, using 10

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
