“…The other elements were found the same that are carbon (C), oxigent (O), and kalium (K) as can be seen at Table I and Table II. Similar result was found for other species of wild silk that having cubic crystal on the surface such as Hyalophora gloveri , Bunaea aleinoc and Antheraea pernyi [1]. Figure 12.…”

Abstract-This Article reporting result from research in providing silk from wild silkmoth cocoon of Attacus atlas. The silkmoth is from Indonesia origin. The research was initiated by collecting the silkmoth egg from their real location. The silkmoth eggs were hatched and the larva were introduce with specific leaf that will be use as a a future food. The consideration in selecting leaf for the food is the leaf should from the three that easily and rapid grow also having ingredient that could be useful in drug, pharmacy and medical purpose. It is found the wild silkmoth Attacus atlas are like to consume a herb plant leaf of Erythrina variegate and also Cananga odorata. The cocoon resulting from feeding the caterpillar of Attacus atlas with these 2 type of leaves were observed by using scanning electron microscope (SEM) and element compositions were detected by using Energy Dispersive X-ray Spectroscopy (EDS). Different appearance of fiber are observed. With feeding with Cananga odroata resulting fiber surface covering with cubic crystal that reach with Calcium (Ca) meanwhile feeding with Erythrina variegate resulting fiber without fibrous surface which is rich with clhorine (Cl).

“…The B. mori cocoon is the most comprehensively studied type of silkworm cocoon in terms of structure and properties (Chen et al, 2012a). So it was used as the main example for analysing impact resistance and damage tolerance in cocoons.…”

“…More applied silkworm research tends to focus on methods to best extract the silk from the cocoons of the domesticated silkworm Bombyx mori or from wild cocoons (Gheysens et al, 2011;Kundu et al, 2012), or indeed on turning those silks into useful textiles or other products. In contrast, the structure of the cocoon itself has largely been ignored, although recent research shows that cocoons can be considered as hierarchical composites composed of silk fibres and sericin bonds, which confers a number of unique properties to the cocoon (Chen et al, 2012a;Chen et al, 2012b;Chen et al, 2012c).…”

“…Importantly, the animal uses a very limited number of material components, usually only silk fibre and sericin. Some cocoons also have additional features, such as extra calcium oxalate crystals on the cocoon surface in A. pernyi cocoons or the incorporation of hairs and spines (Chen et al, 2012a). In addition, some cocoons might display rather large holes, e.g.…”

SUMMARYSilk cocoons, constructed by silkmoths (Lepidoptera), are protective structural composites. Some cocoons appear to have evolved towards structural and material optimisation in order to sustain impact strikes from predators and hinder parasite ingress. This study investigates the protective properties of silk cocoons with different morphologies by evaluating their impact resistance and damage tolerance. Finite element analysis was used to analyse empirical observations of the quasi-static impact response of the silk cocoons, and to evaluate the separate benefits of the structures and materials through the deformation and damage mechanism. We use design principles from composite engineering in order to understand the structure-propertyfunction relationship of silkworm cocoons. Understanding the highly evolved survival strategies of the organisms building natural cocoons will hopefully lead to inspiration that in turn could lead to improved composite design.

Materiomics: An ‐omics Approach to Biomaterials Research

The past fifty years have seen a surge in the use of materials for clinical application, but in order to understand and exploit their full potential, the scientific complexity at both sides of the interface--the material on the one hand and the living organism on the other hand--needs to be considered. Technologies such as combinatorial chemistry, recombinant DNA as well as computational multi-scale methods can generate libraries with a very large number of material properties whereas on the other side, the body will respond to them depending on the biological context. Typically, biological systems are investigated using both holistic and reductionist approaches such as whole genome expression profiling, systems biology and high throughput genetic or compound screening, as already seen, for example, in pharmacology and genetics. The field of biomaterials research is only beginning to develop and adopt these approaches, an effort which we refer to as "materiomics". In this review, we describe the current status of the field, and its past and future impact on the biomedical sciences. We outline how materiomics sets the stage for a transformative change in the approach to biomaterials research to enable the design of tailored and functional materials for a variety of properties in fields as diverse as tissue engineering, disease diagnosis and de novo materials design, by combining powerful computational modelling and screening with advanced experimental techniques.
