Time to progression in the TEA group [median 11.9 months, interquartile range (IQR) 5.6-18 months] was not statistically different from that in the RFA group (median 9.5 months, IQR 3.5-18.7 months) (p = 0.773). CONCLUSION TEA could be an effective alternative of RFA for the local treatment of small HCC; it is especially valuable for tumors of unfavorable location.RNA-cleaving DNAzyme is a very useful biomaterial for metal ions determination. However, parts of DNAzymes can be cleaved by several metal ions, which makes it difficult to distinguish the concentrations of different metal ions. A method was applied to determine the Cu(II) concentration by using electrochemical biosensors combined with a mathematical model. An electrochemical biosensor was fabricated using single carbon nanotubes/field-effect transistor (SWNTs/FET) functionalized with a DNAzyme named PSCu10 and its complementary DNA embedded phosphorothioate RNA (CS-DNA). The CS-DNA with amino groups at the 5' end was immobilized on the SWNTs' surface via the peptide bond and then combined with PSCu10 by identifying bases complementary pairing (Cuzyme/SWNTs/FET). The CS-DNA can be cleaved when Cu(II) bonded with the PSCu10 so that the structural change of Cuzyme improves the electrical conductivity of Cuzyme/SWNTs/FET. But CS-DNA also can be cut-off by the Hg(II) directly, which might interfere with the detection of the Cu(II) concentration using Cuzyme/SWNTs/FET. To solve this problem, Hgzyme/SWNTs/FET was employed to monitor the Hg(II) concentration at the same time, thus serving to determine the Cu(II) content through the Gaussian process regression. The biosensor array can determine the Cu(II) concentration varying from 0.01 to 10,000 nM when the Hg(II) concentration was ranging from 5 to 10,0
