To better understand the life-cycle of a nanoparticle (NP) it is important to study how nanoparticles adhere to substrates. Various removal techniques were used to study the adhesion strength of silver nanoparticles to carbon substrates with different surface chemistries. TEM and IR were used to characterize the NPs and substrate respectively. We developed a qualitative method to determine adhesion strength. A brush is run along the surface and the change in nanoparticle concentration is measured using AAS. Refinement of this process is needed to show a correlation between the force of adhesion and the surface chemistry, namely the determination of surface area of the substrate and precise control over the bristle of the brush.
