Understanding the importance and application of biosensors is complicated by the diverse range of methods and application and some existing text is somewhat technical in nature with little consideration to the novice. This book disseminates information on biosensors in a readable way by having unique sections for the novice and expert alike. Each chapter has an abstract, key facts, applications to other areas of health and disease, a "mini-dictionary" of key terms and summary points. In addition, the book covers optical imaging, surface plasmon resonance, microcantilevers, electrochemistry, aptamers, fluorescence, electrochemistry, nanobiosensors and nanowires.
