Decellularized allografts offer potential as heart valve substitutes and scaffolds for cell seeding. The effects of decellularization on the quasi-static and time-dependent mechanical behavior of the pulmonary valve leaflet under biaxial loading conditions have not previously been reported in the literature. In the current study, the stress-strain, relaxation and creep behaviors of the ovine pulmonary valve leaflet were investigated under planar-biaxial loading conditions to determine the effects of decellularization and a novel post-decellularization extracellular matrix (ECM) conditioning process.

- Researchers successfully used an atomic force microscope (AFM) to create nanometer-scale patterns in self-assembled monolayers (SAMs) made from 1-alkenes on hydrogen-passivated silicon substrates.
- The technique, known as nanoshaving, demonstrates both flexibility and effectiveness in forming well-defined nanoscale features in a controlled way.
- By adjusting the applied load and the number of etching scans, they achieved features with varying depths ranging from 2 to 15 nm, while also comparing the results with patterns created on different surfaces like silicon and mica.
