Silk fibers in the three layers of Attacus atlas (A. atlas) cocoons have morphological structure and tensile properties similar to that of Bombyx mori silk. Attempts are being made to produce silk for commercial applications from cocoons of relatively unknown wild insects due to the unique properties of the fibers and as a source of income and employment. In this research, A. atlas cocoons were used to study the chemical composition, morphology, physical structure and tensile properties of the… 
Mechanical Properties and Biocompatibility of Attacus atlas and Bombyx mori Silk Fibers Released from Cocoons by Alkali Treatment
It is found that 100 mM NaOH concentration was efficient for complete A. atlas cocoon disintegration to individual fibers; while in case of B. mori, near complete hydrolysis was observed at the same concentration as shown SDS-PAGE and weight analysis.
Structure and Functions of Cocoons Constructed by Eri Silkworm
The high sericin content of the cocoon coat, as well as the excellent ultraviolet absorption and antimicrobial abilities of Sericin, allows E cocoons to effectively prevent ultraviolet rays and microorganisms from invading pupae.
Study On Structure And Anti-Uv Properties Of Sericin Cocoons
Abstract Through biogenetic engineering, the posterior silk glands of Bombyx mori larvae are degenerated, and only the middle silk glands are retained to secrete sericin to produce sericin fibers, so
Tensile Properties and Biocompatibility of Indonesian Wild Silk Cricula Trifenestrata: A Preliminary Study
As it is reported in many publication about successful work of many research in developing biomaterial from Bombyx mori silk which is attract many researchers to observe the possibilities in using
Comparative Analysis of Structure and Properties of Stereoscopic Cocoon and Flat Cocoon
Abstract Cocoon is a kind of natural biopolymer material with reasonable structure and various functions. However, its structure and functions are often destroyed in practical application. In this
Non-mulberry Silk Fibers
Wild or non-mulberry silks are produced from various species of insects. Most popular non-mulberry silks that are commercially available are tasar (Antheraea mylitta), eri (Samia cynthia ricini), and
Cytotoxicity Test of Brown Silk from Attacus atlas L. on Rat Smooth Muscle Cells
Natural brown silk biomaterial from silkworm Attacus atlas L. (A. atlas L.) is a biopolymer that has many advantages compared to commercial silk from Bombyx mori (B. mori). The aim of this study was
Impact of different silkworm dietary supplements on its silk performance
This study aims to evaluate the effect of silkworm larva (Bombyx mori) diet supplementation with two amino acids (threonine and valine) on the cocoon production and on the structural and mechanical
Species identification of Bombyx mori and Antheraea pernyi silk via immunology and proteomics
Compared with conventional methods for distinguishing silk species, immunological and proteomics techniques used in tandem can provide intact information and have the potential to provide accurate and reliable information for species identification.
Microfibers as Physiologically Relevant Platforms for Creation of 3D Cell Cultures.
It is shown that microfibers are a highly tunable and versatile tool with great promise for creating 3D cell cultures with specific properties.


Structure and properties of cocoons and silk fibers produced by Hyalophora cecropia
This paper shows that silk fibers produced by cecropia (Hyalophora cecropia) have similar tensile properties but different amino acid composition than that of mulberry (Bombyx mori) silk. The
Tensile properties of Attacus atlas silk submerged in liquid media
Tensile properties of Attacus atlas (Saturniidae) silk were measured in air, water, and ethanol. Control samples in air showed a large variability, so a normalization method was developed to enable
Structure and properties of ultrafine silk fibers produced by Theriodopteryx ephemeraeformis
The composition, morphology, physical structure, thermal stability, and tensile properties of silk fibers produced by bag worms were studied and could be useful for some of the applications currently using the B. mori and wild silk fibers.
