Biological Effect Evaluation of Different Sized Titanium Dioxide Nanoparticles Using Bombyx mori (Silkworm) as a Model Animal.

Titanium dioxide nanoparticles (TiO NPs) are widely used in various disciplines, and it is imperative to evaluate their safety in the environment. In this paper, Bombyx mori (silkworm) was used as a model organism to evaluate the biological effects of different sized TiO NPs, taking into consideration their effect on the larval growth, cocoon shell weight, tissues, and silk produced. The effect of the different sized TiO NPs on the larval and cocoon shell weight was dose-dependent.

Photothermal Regenerated Fibers with Enhanced Toughness: Silk Fibroin/MoS Nanoparticles.

The distinctive mechanical and photothermal properties of Molybdenum sulfide (MoS) have the potential for improving the functionality and utilization of silk products in various sectors. This paper reports on the preparation of regenerated silk fibroin/molybdenum disulfide (RSF/MoS) nanoparticles hybrid fiber with different MoS nanoparticles contents by wet spinning. The simulated sunlight test indicated that the temperature of 2 wt% RSF/MoS nanoparticles hybrid fibers could rise from 20.

A review on the biological effects of nanomaterials on silkworm ().

The production of high-quality silkworm silk is of importance in sericulture in addition to the production of biomass, silk proteins, and animal feed. The distinctive properties of nanomaterials have the potential to improve the development of various sectors including medicine, cosmetics, and agriculture. The application of nanotechnology in sericulture not only improves the survival rate of the silkworm, promotes the growth and development of silkworm, but also improves the quality of silk fiber.
