Cytotoxicity and Endothelial Cell Adhesion of Lyophilized and Irradiated Bovine Pericardium Modified With Silk Fibroin and Chitosan
(WILEY-BLACKWELL, 2011)
Grafts of biological tissues have been used since the 1960s as an alternative to the mechanical heart prostheses. Nowadays, the most consolidated treatment to bovine pericardial (BP) bioprostheses is the crosslinking with ...
Immunosensor for diagnosis of Alzheimer disease using amyloid-beta 1-40 peptide and silk fibroin thin films
(Elsevier Science Bv, 2016)
Layer-by-Layer (LbL) films containing silk fibroin (SF) and the 40 aminoacid-long amyloid-beta peptide (A beta 1-40) were prepared with the purpose of developing a new prototype of an electrochemical immunosensor. The film ...
Silk fibroin-antigenic peptides-YVO4:Eu3+ nanostructured thin films as sensors for hepatitis C
(2016-02-01)
Nanostructured films prepared by Layer-by-Layer technique and containing silk fibroin, antigenic peptide NS5A-1 derived from hepatitis C virus (HCV) NS5A protein and YVO4:Eu3+ luminescent nanoparticles, were utilized in ...
Silk fibroin organization induced by chitosan in layer-by-layer films: Application as a matrix in a biosensor
(2017-01-02)
In this paper, we show that chitosan may induce conformation changes in silk fibroin (SF) in layer-by-layer (LbL) films, which were used as matrix for immobilization of the enzyme phytase to detect phytic acid. Three ...
Silk fibroin/hydroxyapatite composite membranes: Production, characterization and toxicity evaluation
(2020-02-01)
Alloplastic materials based on biopolymers such as silk fibroin (SF) have provided the synthesis of excellent biomaterials for bone repair. The aim of the present study was to produce SF membranes associated to hydroxyapatite ...
Ultrasound-assisted synthesis of organotin compounds and their application as luminescent dye in silk fibroin scaffolds
(2020-05-24)
In this work, we report the green synthesis of four luminescent organotin compounds 1–4 derived from amino acid Schiff bases (1: Naph-Trp-SnPh2, 2: Naph-Tyr-SnBu2, 3: Naph-Tyr-SnPh2, 4: Naph-Phe-SnPh2), obtained by ...
Immunosensor for diagnosis of Alzheimer disease using amyloid-β 1-40 peptide and silk fibroin thin films
(2016-11-01)
Layer-by-Layer (LbL) films containing silk fibroin (SF) and the 40 aminoacid-long amyloid-β peptide (Aβ1-40) were prepared with the purpose of developing a new prototype of an electrochemical immunosensor. The film showed ...
Antibacterial Silk Fibroin/nanohydroxyapatite Hydrogels With Silver And Gold Nanoparticles For Bone Regeneration
(Elsevier Science BVAmsterdam, 2017)
Silk fibroin as a biotemplate for hierarchical porous silica monoliths for random laser applications
(2018-01-01)
Bombyx mori silk fibroin offers unlimited opportunities for functionalization, processing, and biological integration. We describe in this work the design of structured organic inorganic hybrids based on silica and silk ...
