- Abstract
- Mixtures of diethyl glycol dimethyl ether vapors
and argon were used to feed RF (13.56 MHz) glowdischarges
and coat polystyrene substrates with poly(ethylene oxide)
(PEO)-like thin films. Different power input values have been
used to obtain coatings with different cell-adhesive properties.
Cell-culture experiments showed a tight correlation
between the adhesion/morphology of cultured cell-lines and
the chemical composition of the coatings; the ability of PEOlike
coatings to discourage or promote cell adhesion could
thus easily be related to the power delivered to the plasma.
Combined deposition processes of different PEO-like coatings
have been performed, with the method of physical
masking, to produce surfaces micro-patterned with celladhesive
tracks alternating with cell-repulsive domains. The
micro-arrangement of different cell-adhesive domains enabled
the patterning of cell cultures and induced the alignment
of cells along predefined directions.
