Osteogenesis of human adipose-derived stem cells on poly(dopamine)-coated electrospun poly(lactic acid) fiber mats.

Electrospinning is a versatile technique to generate large quantities of micro- or nano-fibers from a wide variety of shapes and sizes of polymer. The aim of this study is to develop functionalized electrospun nano-fibers and use a mussel-inspired surface coating to regulate adhesion, proliferation and differentiation of human adipose-derived stem cells (hADSCs). We prepared poly(lactic acid) (PLA) fibers coated with polydopamine (PDA).

Chitosan-coated electrospun PLA fibers for rapid mineralization of calcium phosphate.

In this work, hydroxyapatite (HA) mineralized on chitosan (CS)-coated poly(lactic acid) (PLA) nanofiber mat was prepared and compared in terms of mineralization characteristics. Significant calcium phosphate crystals formed on various concentrations of CS-coated PLA fiber mat with better uniformity after 2h of incubation in 10 times simulated body fluid (10× SBF). X-ray diffraction results further indicated that the composition of the deposited mineral was a mixture of dicalcium phosphate dehydrates and apatite.

Fabrication of porous carbon nanotube network.

We used the spin-coating method combined with ultrasonic atomization as a continuous, one-step process to generate a two-dimensional honeycomb network that was constructed from pure multi-walled carbon nanotubes.

A tetrahedrally coordinated cobalt(II) phosphonate with a three-dimensional framework containing two-dimensional channels.

The structure of poly[caesium(I) [(micro(4)-ethylenediphosphonato)cobalt(II)]], {Cs[Co(C(2)H(5)O(6)P(2))]}(n), reveals a three-dimensional polymeric open framework consisting of tetrahedral Co(II) atoms coordinated by four different ethylenediphosphonate O atoms and intermolecular O-H...
