Abstract

Biosensors are promising analytical tools for the determination and characterisation of bioactive compounds in wines, providing fast, sensitive and costeffective detection, assisting in the assessment of quality, sensory and safety attributes of wines. In this chapter, some of the most representative, recent examples of biosensors for the detection of polyphenols, biogenic amines, mycotoxins and allergens in wine are discussed, emphasizing the wealth of biosensing strategies and the particularities of wine as a complex analytical matrix.
