Smart nanosensors and methods for detection of nanoparticles and their potential toxicity in air

Nanoparticles are increasingly used in various products, and their unavoidable release into the environment is a becoming major concern. In order to understand their effects in environment components (air, soil, water), important stages are detection of nanoparticles in environment and their toxicity. The current chapter is provided a detailed overview of the background information of nanoparticles, their detection methodology and interaction with air. In the section of detection of nanoparticles, we are focusing on the sample in matrix, sample preparation methods and detection techniques. Available analytical sample preparation and detection techniques as well as emerging techniques such as electroanalytical and sensors based, are also presented. This section also includes overview potential gaps and advantages in the analytical methodology. This chapter also evaluates the toxicity of these nanoparticles in environment with focusing interaction in air. For this purpose, their release, transformation and toxicity approaches were examined with available literature examples.
