构建具有灵敏度高、选择性好、线形范围宽等优异特性的生物传感器是分析化学领域的永恒目标。同济大学化学系田阳研究小组报道了基于金/针状二氧化钛纳米(Au/TiO2)复合膜的细胞色素c(Cyt.c)直接电子传递,同时通过Au NPs的等离子共振诱导其氧化还原电流的增大,从而提高了检测H2O
The construction of biosensors with excellent characteristics such as high sensitivity, good selectivity and wide linear range is the eternal goal in analytical chemistry. The Tianyang team at Tongji University reported the direct electron transfer of cytochrome c (Cyt.c) based on the gold / acicular titania nanocomposite film and the increase of its redox current through the plasma resonance of Au NPs Large, thus increasing the detection of H2O
