Secondary structures calculated from analysis of the IR spectra covering the amide I region (1735–1580 cm–1) of freeze dried silk from T. lintearius, degummed silk fibroin from B. mori, and the nanoparticles obtained from them. Data are expressed as mean ± SD (n = 3). Groups denoted by different letters are statistically different (p < 0.05).
