Abstract

With advances in nanotechnology, particles with various size, shape, surface chemistry, and composition can be easily produced. Nano- and microparticles have been extensively explored in many industrial and clinical applications. Ensuring that the particles themselves are not possessing toxic effects to the biological system is of paramount importance. This paper describes a proof of concept method, in which a microfluidic system is used in conjunction with a cell microarray technique aiming to streamline the analysis of particle-cell interaction in a high throughput manner. Polymeric microparticles, with different particle surface functionalities, were first used to investigate the efficiency of particle-cell adhesion under dynamic flow. Silver nanoparticles (AgNPs, 10 nm in diameter) perfused at different concentrations (0 to 20 μg/mL) in parallel streams over the cell microarray exhibited a higher toxicity compared to the static culture in the 96-well-plate format. This developed microfluidic system can be easily scaled up to accommodate a larger number of microchannels for high throughput analysis of the potential toxicity of a wide range of particles in a single experiment.
