of the proteins can affect the number and accessibility of inter-
action sites possible between different functional groups and the
colloid. IS will alter the conformation of the protein. A high IS
solution caused protein folding and compression, resulting in
low A values [20].

Bacterial adhesion and desorption to a surface are the
residence-time-dependent processes [28,35,36]. The time
dependence of this process can be regarded as the result of
the interaction and attraction of bacterial exopolymers (e.g.,
proteins, lipopolysaccharides, and other biopolymers) to the
ical bonds of the polymers with the surface. The bond between
biopolymers and a surface may strengthen or weaken over time,
leading to adsorption and desorption rates that vary between bac-
terial strains [36]. The functional groups examined here (OH,
COOH, and NH2) are ubiquitous in the biopolymers on the bac-
terial cell surface. The current work with these functionalized
groups highlights the importance of both the specific functional
group as well as residence time on the adhesion force between
effects observed here with these functional groups over time
occur with polymers on the surfaces of bacteria. It has been
found, for example, that adhesion force between an AFM tip
and a bacterial surface increases over time [28], consistent with
our expectations based on results from the current study. Taken
together, these observations demonstrate the importance of spe-
cific molecular-scale interactions between functional groups and
surfaces conditioned with proteins and other polymers, and help
us to better understand factors that affect bacterial adhesion.

The OH-functionalized latex colloid produced the higher
adhesion forces than COOH or NH2-functionalized colloids
to three of the four proteins (BSA, lysozyme, poly-d-lysine).
The NH2-functionalize colloid exhibited the smallest adhesion
force. The adhesion forces between functionalized colloids and
protein-coated surfaces increased with residence time due to
protein rearrangement and water exclusion over time (<100 s).
Adhesion forces decreased inversely with IS in all cases, likely
as a result of conformational and size changes of the proteins in
response to solution IS.
These AFM measurements demonstrate the importance of
molecular-scale interactions between proteins and specific func-
tional groups on surfaces. Studying these specific interactions
will help us to better understand the interactions between bacte-
rial cell surfaces, which are composed of a complex mixture of
proteins, polysaccharides and other biopolymers, and surfaces
which are often pre-conditioned by organic matter in water. A
better understanding of interactions of functional groups and
biopolymers at the molecule scale will improve the understand-
ing the factors that influence microbial adhesion, leading to
improved methods to control adhesion.
