Tuning compliance of nanoscale polyelectrolyte multilayers to modulate cell adhesion.
It is well known that mechanical stimuli induce cellular responses ranging from morphological reorganization to mineral secretion, and that mechanical stimulation through modulation of the mechanical properties of cell substrata affects cell function in vitro and in vivo. However, there are few approaches by which the mechanical compliance of the substrata to which cells adhere and grow can be ...
متن کاملSmooth Muscle Cell Phenotype Modulation and Contraction on Native and Cross-Linked Polyelectrolyte Multilayers
Smooth muscle cells convert between a motile, proliferative "synthetic" phenotype and a sessile, "contractile" phenotype. The ability to manipulate the phenotype of aortic smooth muscle cells with thin biocompatible polyelectrolyte multilayers (PEMUs) with common surface chemical characteristics but varying stiffness was investigated. The stiffness of (PAH/PAA) PEMUs was varied by heating to fo...
متن کاملSplaying hyperthin polyelectrolyte multilayers to increase their gas permeability.
The concept of splayed, hyperthin polyelectrolyte multilayers (PEMs) is introduced in which a bulky, hydrophilic and charged pendant group is used to increase the gas permeability of a PEM without reducing its permeation selectivity. Proof of principle studies are reported using nm-thick PEMs made from poly(sodium 4-styrene sulfonate) () and poly(allylamine hydrochloride) () bearing bulky cobal...

The polyelectrolytes poly(L-lysine) (PLL, Mw = 2.60 × 10 Da) and hyaluronic acid (HA, Mw = 1.32 × 10 Da) were purchased from Sigma Aldrich (Saint-Quentin Fallavier, France) and Lifecore Biomedical (Chaska, USA) respectively. Coupling agents as N,N′Dicyclohexylcarbodiimide 99% (DCC), N-(3-Dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride ≥ 98% (EDC), N-Hydroxysuccinimide 98% (NHS), and NHy...
