Evidence is presented here that cupric ions play a part in the natural spinning of Bombyx mori silk. Proton induced X-ray emission studies revealed that the copper content increased from the posterior part to the anterior part of silk gland, and then further increased in the silk fiber. Spectrophotometric analysis demonstrated that cupric ions formed coordination complexes with silk fibroin cha...
Introduction Past experiments have already proven that silk, a natural protein produced by silkworms and spiders, exhibit intriguing physical properties such as exceptionally high moduli and toughness. Silk fibroins (SF) can be further reconstituted into ultrathin (<100 nm) films while retaining most of these properties for a wide variety of bioapplications. These ultrathin films can be further...
Abstract Background Mulberry silkworm ( Bombyx mori L.) is one of the best-studied insect models, regularly used as a type specimen for thermal tolerance experiments on insects. Still, upper lethal limit this lepidopteran has never been explored extensively using any sort conventional assay method. The present study deals with employment different protocols survivorship three breeds mulberry B....
The infection of Bombyx mori nucleopolyhedrovirus (BmNPV) in silkworms is often lethal. It is difficult to prevent, and its lethality is correlated with both viral particle characteristics and silkworm strains. Low doses of titanium dioxide nanoparticles (TiO2 NPs) can promote silkworm growth and improve its resistance to organophosphate pesticides. In this study, TiO2 NPs' effect on BmNPV resi...
