“…Thus, it is extremely significant to detect TB for early diagnosis and prognosis judgment. Up to now, various techniques have been reported for the determination of TB, for example, electrochemiluminescence [8], chemiluminescence [9], surface enhanced Raman spectroscopy [10], fluorescence [11, 12] and electrochemical method [13–15]. Among these, special attention has been paid on the electrochemical strategy due to its relatively cheap equipment, simple operation, rapid response and high sensitivity [15, 16].…”
