Chemosensor Arrays: Fundamental Pattern Recognition, Development and Applications provides practical advice for anyone interested in pattern recognition-driven chemical sensing. Sections will help researchers working on the design and application of chemosensor arrays, giving them the tools they need to accurately interpret data patterns in molecular recognition chemistry. Beginning with an introduction to chemosensing, its principles, and the fundamentals of computational principles and methods, the book goes on to explore key design strategies and examples with chapters on a biological nose, artificial nose, and artificial tongue. Applications for real-world scenarios are then discussed, along with considerations of future needs and developments. As demand has increased for innovative methods in simple everyday monitoring, chemists are focusing on chemical sensors based on molecular recognition chemistry. Conventional approaches involved the development of selective chemical sensors to specifically detect species of interest, whilst more recent studies have revealed the potential of cross-reactive molecular recognition. Such approaches, combined with pattern recognition, are a powerful technique to gain much qualitative and quantitative information. Outlines the chemical knowledge needed to support the rational molecular design of chemosensors for pattern recognition Discusses successful data pre-processing and accurate interpretation of results, highlighting the importance of avoiding misinterpretation or overinterpretation of results Provides guidance on array design with strategies for developing artificial tongues and noses for chemical sensing
