abstract = {The interaction between neurons and nanostructured
materials is an increasing interest due to the possibility
to manipulate the cells on the length scale of an individual
biomolecule. A comprehensive understanding of neuron
adhesion to non-biomaterials opens promising strategies to
design neuronal network and for neuron-electrode
integration. The neuronal adhesion can be mediated by
specific receptor-ligand or non-specific interactions. The
specific cell adhesion is often associated with the
interactions between cell surface receptors (integrins)and
their respective ligands from the extra cellular matrix
(ECM) components or between hemophilic neuronal cell
adhesion molecules (NCAMs) for cell-cell interactions. The
nonspecific cell adhesion is mainly induced by electrostatic
interactions. NCAMs are associated with the negatively
charge polysialic acid (PSA) and are known to be crucial for
regulating neuronal adhesion. Previously, the chemical
ligand 11-amino-1-undecanethiol (AUT)possessing positively
charged terminals have been used to functionalize gold
nanoparticles(AuNPs) on the substrate for tuning the neuron
adhesion and neurite outgrowth. However, the preparation of
cell culture samples has been restricted to the
immobilization of disordered AuNPs only. Moreover, it has
been found that the attachment of these AuNPs on the surface
has been instable during long time cell culture, which
results in particle aggregation and cytotoxicity due to
particle uptake. Although the cell adhesion is obviously
mediated by the electrostatic interactions, further studies
to understand how charges and mechanical properties of the
substrates affect the cell adhesion and neurite outgrowth
are still missing. In this work, the block copolymer micelle
nanolithography is used to synthesize both ordered and
disordered AuNP arrays of different sizes and densities.
Moreover, weakly bound (WB) and strongly bound(SB) AuNPs on
the substrates can be obtained by tuning the oxygen plasma
exposure time. The AuNPs are used as nanoplatforms to carry
the AUT ligands, while the background is blocked by cell
aversive molecules of
2-[methoxyl(polyethyleneoxy)6-9-propyl]trichlosilane (PEG).
