An electrical microenvironment constructed based on electromagnetic induction stimulates neural differentiation

Abstract

A NH2-MXene/PLLA nerve conduit with a conductive network structure is constructed by laser additive manufacturing, which can generate electrical signals driven by electromagnetic induction, and the generated electrical signals can promote the differentiation of nerve cells.

Piezoelectric Polarization Enhanced Photogenerated Carrier Separation of Bi2S3–BaTiO3 Nanostructure-Based Photoelectric Poly-L-lactic Acid Scaffold for Stimulating Cell Growth

“…Compared with other groups, the PLLA/Bi 2 S 3 –BaTiO 3 bone scaffold exhibited a higher cell count and improved cell spreading when exposed to light and ultrasound stimulation. It was observed that adjacent cells overlapped, suggesting that the enhanced electrical stimulation of the bone scaffold may be responsible for these effects. , …”

“…It was observed that adjacent cells overlapped, suggesting that the enhanced electrical stimulation of the bone scaffold may be responsible for these effects. 36,37 After 3 days of cell culture, the viability of cells on different bone scaffolds was assessed using a live/dead fluorescence staining assay. 38 In this assay, live cells were stained green, while dead cells were stained red.…”

Sustained Endogenous Nitric Oxide Catalytic System Endows Skin Scaffolds with Antibiofilm and Antibacterial Activities

“…After ultrasonically stirring and drying, the mixed powder was further mechanically ground for 30 min. A PPDO/Cu@ZIF-8 porous skin scaffold was prepared by a selective laser sintering (SLS) technique according to the previous process. − The preparation parameters were set as a laser scanning speed of 400 mm/s, laser power of 6 W, a line spacing of 0.24 mm, and a monolayer thickness of 0.15 mm. In addition, the PPDO/ZIF-8 and PPDO scaffolds were prepared with the same parameters set as the comparison groups.…”

Oxygen vacancy healing boosts the piezoelectricity of bone scaffolds

“…Initially, the hydrophilicity of all scaffolds was evaluated because it could influence cell adhesion and proliferation. [57][58][59] Obviously, the PLLA scaffold exhibited hydrophobicity ascribed to its water contact angle reaching 90°(Fig. 6a).…”
