Objective

How does nanoparticle presence affect
cellular function and behavior?


Little is known on how they interconnect
with cytoskeleton
Long term goals
Which nanoparticles are most efficient?
 What is the best way to deliver the
nanoparticles?

Methodology



Perform cell cultures with Mammalian SaOS-2 cells
Obtain either Magnetite or Gadolinium nanoparticle
cells
Encapsulate nanoparticles in liposomes


Prevents formation of large aggregates and increases
biocompatibility
Introduce nanoparticles to SaOS-2 cells and record
effect
