水凝胶机械性能测试

简介：The Piuma Nanoindenter is a new and versatile instrument for the characterization of the mechanical properties of soft hydrogels. Check our recently released application note on agarose and gelatin to get an impression about some essential measurements the Piuma can perform! And it does not stop here: very soft hydrogels, other biomaterials, tissues, cell sheets and even single cells are all part of the Piuma domain, which provides researchers with unparalleled accuracy and ease of use in mechanical experiments.利用piuma生物纳米压痕研究水凝胶的力学性质，包括杨氏模量，表面形貌等性质。

骨水泥的杨氏模量测试

简介：Biosilica, a biocompatible, natural inorganic polymer that is formed by an enzymatic, silicatein-mediated reaction in siliceous sponges to build up their inorganic skeleton, has been shown to be morphogenetically active and to induce mineralization of human osteoblast-like cells (SaOS-2) in vitro. In the present study, we prepared beads (microspheres) by encapsulation of β-tricalcium phosphate [β-TCP], either alone (control) or supplemented with silica or silicatein, into the biodegradable copolymer poly(D,L-lactide-co-glycolide) [PLGA]. Under the conditions used, ≈5% β-TCP, ≈9% silica, and 0.32 μg/mg of silicatein were entrapped into the PLGA microspheres (diameter≈800 μm). Determination of the biocompatibility of the β-TCP microspheres, supplemented with silica or silicatein, revealed no toxicity in the MTT based cell viability assay using SaOS-2 cells. The adherence of SaOS-2 cells to the surface of silica-containing microspheres was higher than for microspheres, containing only β-TCP. The formation of new bone induced by the microspheres is also evident from measurements of the stiffness/reduced Young's modulus of the regenerated bone tissue. The reduced Young's modulus of the regenerating bone tissue around the implants was markedly higher for the silica-containing microspheres (1.1 MPa), and even more for the 1:1 mixture of the silica- and silicatein-containing microspheres (1.4 MPa), compared to the β-TCP microsphere controls (0.4 MPa). We propose that based on their morphogenetic activity on bone-forming cells in vitro and the results of the animal experiments presented here, silica/ biosilica-based scaffolds are promising materials for bone repair/regeneration.
