Conteúdo: | In this book chapter, we report the recent advances in the development and application of chemical sensors based on green composite materials for environmental analysis. Emphasis is given on the sensor performance in terms of materials employed (including macromolecules from vegetal sources combined with varied nanostructures), structure–property relationships, and device fabrication technology. Specifcally, the chapter focuses on green materials obtained from vegetal biomass including cellulose, lignin, starch, alginate, pectin, and vegetal protein, indicating the viability for the construction of non-toxic, recyclable, renewable, and biodegradable devices. Firstly, a brief overview on different types of chemical sensors, including electronic tongues, electrochemical sensors, and chemical optical sensors, is presented. Then, the general aspects of green composites as sensing layers are outlined and discussed with respect to their application in environmental analytical chemistry. Emphasis is placed on results reporting the detection of heavy metals and bacterial contamination in water as wells as hazardous volatile organic compounds. Lastly, a brief perspective on the challenges and upcoming opportunities toward the development of novel sensing devices based on green composites is discussed
