Interactions between endothelial and stromal cells are important for vascularization of regenerating tissue. Fibroblasts (FBs) are responsible for expression of angiogenic growth factors and matrix metalloproteinases, as well as collagen deposition and fibrotic myocardial remodeling. Recently, self-assembling peptide nanofibers were described as a promising environment for cardiac regeneration ...

Using a stainless steel mesh as a template collector, electrospun nanofiber meshes with well-tailored architectures and patterns were successfully prepared from biodegradable poly (epsilon-caprolactone) (PCL). It was found that the resulting PCL nanofiber (NF) meshes had similar topological structures to that of the template stainless steel mesh. Such PCL nanofiber meshes (NF meshes) had improv...

Staphylococcus aureus is a virulent pathogen and a major causative agent of superficial and invasive skin and soft tissue infections (SSSTIs). Antibiotic resistance in S. aureus, among other bacterial pathogens, has rapidly increased, and this is placing an enormous burden on the health care sector and has serious implications for infected individuals, especially immunocompromised patients. Alt...

Herein, a robust method to fabricate expanded nanofiber scaffolds with controlled size and thickness using a customized mold during the modified gas-foaming process is reported. The expansion of nanofiber membranes is also simulated using a computational fluid model. Expanded nanofiber scaffolds implanted subcutaneously in rats show cellular infiltration, whereas non-expanded scaffolds only hav...

Continuous nanofibers fabricated by the electrospinning technique have found increasing applications (e.g., nanofiber composites, nanofiber devices, bioengineering tissue scaffolding, etc.). For a nanofiber network subjected to a small external perturbation, the fiber segments within the network may deflect and stick to each other under the condition that their surface adhesion energy overcomes...

A dual pH and glucose responsive boronic acid containing nanofiber was constructed for the reversible capture and release of lectins. The effects of surface groups and pH values on selective lectin capture were investigated by fluorescence microscopy. Compared to the pristine nanofibrous membrane, glucose and galactose functionalized nanofiber surfaces showed significantly higher capture of Con...
