In spite of all the efforts on deciphering such spinning process of spiders, the underlying mechanism currently is yet to be fully revealed. In this research, we designed a novel approach to quantitatively estimate the overall concentration change of spider silk along the progression of liquid-to-solid silk transition from the gland silk. As a prior characterization, we first studied the influe...
We present a silk biomaterial platform with highly tunable mechanical and degradation properties for engineering and regeneration of soft tissues such as, skin, adipose, and neural tissue, with elasticity properties in the kilopascal range. Lyophilized silk sponges were prepared under different process conditions and the effect of silk molecular weight, concentration and crystallinity on 3D sca...
Bombyx mori (silkworm) silk proteins have been utilized as unique biomaterials for various medical applications. To develop a novel affinity silk material, we generated a transgenic silkworm that spins silk protein containing the fibroin L-chain linked with the single-chain variable fragment (scFv) as a fusion protein. Previously, the scFv-conjugated "affinity" silk powder specifically immunopr...
Arthropods face several key challenges in processing concentrated feedstocks of proteins (silk dope) into solid, semi-crystalline silk fibres. Strikingly, independently evolved lineages of silk-producing organisms have converged on the use of liquid crystal intermediates (mesophases) to reduce the viscosity of silk dope and assist the formation of supramolecular structure. However, the exact na...
Silk-based medical products have a long history of use as a material for surgical sutures because of their desirable mechanical properties. However, silk fibroin fabric has been reported to be haemolytic when in direct contact with blood. The layer-by-layer self-assembly technique provides a method for surface modification to improve the biocompatibility of silk fibroin fabrics. Regenerated sil...
Background: Laparoscopic Surgery (LS) may be associated with many port site complications such as hernia, bleeding, infection, subcutaneous emphysema and ugly scars. Some of these complications are serious such as obstructed port site hernia . Rate of these complications is low depending on size and site of the port incision, type of the trocar that it is used, the condition of the patient a...
The primary objective of this research is to elucidate the interactions, mechanisms and biochemistry of the spider silk producing process at the molecular level. Our primary focus is to characterize the protein-rich fluid in the various spider silk producing glands. We have been using a battery of magnetic resonance methods including solution and solid-state nuclear magnetic resonance (NMR) and...
Silk Fibers has emerged as a versatile biomaterial for regenerative medicine. In article 2203237, Christine Radtke and co-workers use silk-based nerve conduit filled with spider silk fibers to treat rat sciatic defect. The silk-in-silk achieves similar performance the current gold standard, autograft, represents promising approach reconstruction.
