Highlighted Nanoindentation Applications
Development of label-free biophysical marker in osteogenic maturation: Massimo Vassali’s group from Genova demonstrated correlation between morpho-mechanical features of osteoblasts and their maturation.
The NSL complex maintains nuclear architecture stability via lamin A/C acetylation: Remi Peyronnet’s group from the UHZ in Freiburg measured the stiffness of the cytoplasm and nuclei with the CHIARO in order to understand nuclear mechanostability.
A multilayer micromechanical elastic modulus measuring method in ex vivo human aneurysmal abdominal aortas: the researchers from VU Medical Center Amsterdam have correlated results of quantitative immunofluorescence and elastic properties of abdominal aortic aneurysm tissue.
Changes in Epithelial and Stromal Corneal Stiffness Occur with Age and Obesity: the group of prof. Vickery Trinkaus-Randall from Boston University School of Medicine has found that elastic modulus was decreased in pre-Type 2 diabetic obese mice while it increased with age.
Environmental elasticity regulates cell-type specific RHOA signaling and neuritogenesis of human neurons: Timothy Gomez et al. used the PIUMA to investigate effects of various stiffness polyacrylamide and collagen hydrogels as an micro-environment for the developing hMNs and hFB neurons.
Stiffness of hydrogels for self-healing & controlled drug delivery matrices: Itamar Willner’s group from Hebrew University utilized the PIUMA to study how stiffness of constitutional dynamic network (CDN)-guided hydrogels can be controlled.
Tailoring the collagen film structural properties via direct laser crosslinking of star-shaped polylactide for robust scaffold formation: Peter Timashev’s group from the RAS in Moscow used the PIUMA to characterize changes in collagen-based scaffolds due to laser-induced curing.
Catechol-mediated and copper-incorporated multilayer coating: An endothelium-mimetic approach for blood-contacting devices: the researchers at Sichuan University, Chengdu, China have included mechanical tests by Piuma to compare coatings before and after copper coordination.
