Analysis of microbial contamination in nanoparticle formulations.
This chapter describes a procedure for quantitative determination of microbial contamination of a nanoparticle formulation. The protocol includes tests for yeast, mold, and bacteria using Millipore sampler devices. This approach is primarily intended to avoid contamination of cell cultures and transmitting potential microbial contaminants to animals in preclinical studies of efficacy, biodistribution, and toxicity. Other methods common to microbiology will likely work equally well.
