 Polyanalyne nanowires have been developed as a novel platform for the detection of cardiac biomarkers such as myoglobin, myo, cardiac troponin I, acetin I, creatine kinase Mb, CKMB, and B-type natriuretic peptide, BNP. These nanowires are capable of detecting extremely low levels of these biomarkers, making them ideal for early detection of heart failure and for determining the stage of the disease. Additionally, they offer a faster response time than traditional methods, making them more reliable and efficient. Furthermore, their biocompatibility with MABS makes them suitable for use in other biosensors for cancer or other diseases.
