This review (with 131 references) summarizes the progress made in the past years in the field of nanomaterial based sensing of serotonin (5-HT). An introduction summarizes the significant role of 5-HT as a biomarker for several major diseases, methods for its determination and the various kinds of nanomaterials for use in electrochemical sensing process relies principally on a precise choice of electrodes...
The authors describe an ultrasensitive electrochemiluminescence (ECL) based aptasensor for myoglobin, a biomarker for the early diagnosis of heart attack (myocardial infarction). A nanocomposite was prepared from reduced graphene oxide, ruthenium(II)-tris(2,2- bipyridyl), samarium oxide and chitosan and placed on the surface of a ccreen-printed carbon electrode (SPCE). The aptamer was immobilized...
