abstract = {We describe the formation and structure of
nucleolipid/dendrimer multilayer films controlled by non-
covalent interactions to obtain biomaterials that exhibit
molecular recognition of nucleic acids. Layers of cationic
poly(amidoamine) (PAMAM) dendrimers of generation 4 and the
anionic nucleolipids 1,2-
dilauroyl-sn-glycero-3-phosphatidylnucleosides (DLPNs) based
on uridine (DLPU) and adenosine (DLPA) were first formed at
the silica–water interface. The PAMAM/DLPN layers were
then exposed to short oligonucleotides, polynucleotides and
single stranded DNA (ssDNA). The interfacial properties were
characterized using quartz crystal microbalance with
dissipation monitoring, attenuated total reflection Fourier
transform infrared spectroscopy and neutron reflectometry.
Both types of DLPN were found to adsorb as aggregates to
preadsorbed PAMAM monolayers with a similar interfacial
structure and composition before rinsing with pure aqueous
solution. Nucleic acids were found to interact with
PAMAM/DLPA layers due to base pairing interactions, while
the PAMAM/DLPU layers did not have the same capability. This
was attributed to the structure of the DLPA layer, which is
formed by aggregates that extend from the interface towards
the bulk after rinsing with pure solvent, while the DLPU
layer forms compact structures. In complementary experiments
using a different protocol, premixed PAMAM/ DLPN samples
adsorbed to hydrophilic silica only when the mixtures
contained positively charged aggregates, which is
rationalized in terms of electrostatic forces. The
PAMAM/DLPA layers formed from the adsorption of these
mixtures also bind ssDNA although in this case the
adsorption is mediated by the opposite charges of the film
and the nucleic acid rather than specific base pairing. The
observed molecular recognition of nucleic acids by
dendrimers functionalized via non-covalent interactions with
nucleolipids is discussed in terms of biomedical
applications such as gene vectors and biosensors.},
