Nanocomposite gold-silk nanofibers.

Assembly of DNA-functionalized gold nanoparticles on electrospun nanofibers as a fluorescent sensor for nucleic acids.

A facile approach was developed to assemble DNA-functionalized gold nanoparticles on the electrospun nanofibers. This novel nanocomposite was successfully applied to constructing a highly sensitive and selective fluorescent sensor for nucleic acids.

Silk Fibroin/Gold Nanocrystals: A New Example of Biopolymer-based Nanocomposites

The dispersion of nanoparticles in ordered polymer nanostructures can provide control over particle location and orientation, and pave the way for tailored nanomaterials that have enhanced mechanical, electrical, or optical properties. Here we used silk fibroin, a natural biopolymer, to embed gold NCs (nanocrystals), so as to obtain well-ordered structures such as nanowires and self-assembled t...

Electrospun silk fibroin nanofibers promote Schwann cell adhesion, growth and proliferation

In this study, Schwann cells, at a density of 1 × 10(5) cells/well, were cultured on regenerated silk fibroin nanofibers (305 ± 84 nm) prepared using the electrospinning method. Schwann cells cultured on the silk fibroin nanofibers appeared more ordered, their processes extended further, and they formed more extensive and complex interconnections. In addition, the silk fibroin nanofibers had no...

A novel inexpensive method for preparation of silk nanofibers from cocoons

AbstractIn the present study , a novel method for the production of silk nano fibers are presented . In this way , a mechanical and easy technique is used instead of toxic and costly chemical methods . Also , the separation of silk nano fibers from the cocoon was carried out by mechanical homogenizer and probe ultrasonic homogenizer . After the preparation of silk nanofibers , the product was c...
