“…1D inset), which was evaluated by Randles-Sevcik equation using K 3 Fe(CN) 6 /K 4 Fe(CN) 6 as an indicator (Jiang & Wang, 2009;Sun, Qin, Zhao, & Jiao, 2010): I p = (2.687 Â 10 5 ) n 3/2 t 1/2 D 1/2 AC (Jiang & Wang, 2009), where n = 1, t is scan rate (V s À1 ), D = 5.7 Â 10 À6 cm 2 s À1 and C is the concentration (mol cm À3 ) of the K 3 Fe(CN) 6 /K 4 Fe(CN) 6 ; The effective surface area (A) is proportional to I p /t 1/2 which is shown in the inset of Fig. 1D.…”

Real-Time Evaluation of Live Cancer Cells by an in Situ Surface Plasmon Resonance and Electrochemical Study

“…Electrochemical techniques are widely used in biomedical applications, such as detection of bioactive molecules , and determination of interactions between bioactive agents and biological supramolecules. − Jiang and co-workers proposed a highly sensitive electrochemical method for analyzing daunorubicin (DNR) with a low detection limit of 10 nM and a wide linear range of 10–500 nM. Moreover, analysis of cell features − and evaluation of the therapeutic efficiency of drugs , are also possible because of their simple operation process, fast response speed, high sensitivity, and good accuracy.…”
