Formulation
Flexibility: |
|
|
|
|
|
|
|
Size of the
nanoparticle and the physical properties of the resulting
aggregate can be controlled during the synthesis |
|
|
|
|
|
|
|
In Vivo physical
properties of the aggregates can be varied to provide material
that behaves like adipose tissue, collagen or articular
cartilage. |
|
|
|
|
|
|
|
Aggregates can be
designed to provide a variety of porosites for optimum tissue
growth if desired. |
|
|
|
|
|
|
|
Aggregates have
been optimized to perform with elastic shear and bulk material
moduli that mimic biological tissue found at different levels
of the dermal strata. |
|
|
|
|
|
|
|
Molecules can be
incorporated into the aggregates during formation for
subsequent controlled release. |
|
|
|
|
|
|
|
Physical
properties such as strength and porosity of the aggregates
can be varied by changing the nanoparticle size and with
subtle changes in the composition ratio of monomers used in
polymerization and crosslink density. |
|
|
|
|
|
|
|
The rate of pore
formation and cellular infiltration can be controlled to
optimize tissue regeneration. |
