The AgNPs-EW were primarily characterized by UV-Vis absorption spectroscopy (Shimadzu UV spectrophotometer UV-2600). Fourier transform infrared spectroscopy (FTIR) was employed to characterize the interaction between the silver nanoparticles and protein present in the egg-white, and FTIR spectra were recorded in the range from 4000 to 400 cm⁻¹ using a Spectrum RX-IFTIR (Perkin Elmer Massachusetts, USA). Lyophilized egg-white served as a control. Dynamic light scattering (DLS) analysis was carried out using a zeta sizer (Malvern Instrument Co. Ltd., UK) for evaluation of the AgNPs-EW stability. This analysis was performed using duplicate measurements and the size distribution on correlator software version Zetasizer 7.11. All the samples were diluted 100× with double distilled water before analysis.
Zeta potential measurements were carried out using a zeta sizer (Malvern Instrument Co. Ltd., UK) in a disposable cell at 25 °C. DLS and zeta potential measurements were performed to study the stability of AgNPs-EW. These measurements were carried out between 1 to 3 h after the preparation of the AgNPs-EW. The surface morphology and particles sizes of the AgNPs-EW were observed using high-resolution transmission electron microscopy (Hitachi H-7500).

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.
