Bridging the gap between research and clinical application, Biosensors and Molecular Technologies for Cancer Diagnostics explores the use of biosensors as effective alternatives to the current standard methods in cancer diagnosis and detection. It describes the major aspects involved in detecting and diagnosing cancer as well as the basic elements of biosensors and their applications in 5/5(1). Development of electrochemical biosensors One of the chief attractions of biosensors is the remarkable specificity that their biological component confers on them. Enzymes are the most commonly used reagents, but many other biologicals and bio‐ mimics have also been featured. biosensors are presently being developed for environmental analysis. Anti-PAH antibody molecules can be coupled with electronic transducers to provide new biosensor technology for the rapid determination and quantification of PAHs. Although PAHs are not immunogenic on their own, advances in immunology have provided the means toFile Size: 1MB.
