Aptamer-based Biosensor for Environmental Monitoring
Since their discovery, aptamers have captivated the attention of researchers. Today aptamers are available for a wide variety of target molecules ranging from metal ions to whole cells. In this chapter the description of aptamer production and of their interesting properties for biosensing are reported. Applications to environmental monitoring, such as detection of pathogens, toxins, drugs, and organic and inorganic pollutants, are also illustrated.
