FT-IR spectra of commercial sericin (Sigma-Aldrich, MO, USA) and the sericin extract were analyzed using the VERTEX 70 Fourier transform infrared spectrometer (Bruker, Ettlingen, Germany). Spectra of the samples were detected in the range from 4000 to 400 cm-1 with a spectral resolution of 4 cm-1. Each spectrum was scanned 100 times, and then the average was recorded for analysis.

The surface morphology of freeze-dried hydrogels swelled at different swelling conditions were analyzed using a scanning electron microscope (JSM-6400; JEOL Co., Ltd., Tokyo, Japan). Prior to the observation, the hydrogel surfaces were coated with platinum (SB1361; Jieou Road Science and Trade Co., Ltd, Beijing, China) to render them electrically conducive. The FTIR spectra of the prepared hydrogel and dried CSEL were recorded on VERTEX 70 Fourier transform spectrometer (Bruker Optics, Karlsruhe, Germany) with a wavelength range of 4000 to 400 cm -1 , using the KBr disk method with a mass ratio of sample to KBr 1:100.

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.
