Biosensors are devices that detect the presence of microbials suchas bacteria, viruses or a range biomolecules, including proteins,enzymes, DNA and RNA. For example, they are routinely applied formonitoring the glucose concentration in blood, quality analysis offresh and waste water and for food control. Nanomaterials are idealcandidates for building sensor devces: where in just a fewmolecules can alter the properties so drastically that thesechanges may be easily detected by optical, electrical or chemicalmeans. Recent advantages have radically increased the sensitivityof nanomaterial-based biosensors, making it possible to detect oneparticular molecule against a background of billions ofothers.
Focusing on the materials suitable for biosensor applications, suchas nanoparticles, quantum dots, meso- and nanoporous materials andnanotbues, this text enables the reader to prepare the respectivenanomaterials for use in actual devices by appropriatefunctionalization, surface processing or directed self-assembly.The emphasis throughout is on electrochemical, optical andmechancial detection methods, leading to solutions for today's mostchallenging tasks.
The result is a reference for researchers and developers,disseminating first-hand information on which nanomaterial is bestsuited to a particular application - and why.
