pH值测定是许多生物化学和生物过程的先决条件。采用电化学电位法和位点结合法研究了氧化锌（ZnO）纳米棒作为细胞内pH传感器的敏感性。这些纳米棒的尺寸变化，半径在50-300 nm之间，长度在2和10 μ m之间。ZnO纳米棒在室温下对pH范围（1-14）显示出约59 mV/decade的高灵敏度，假设溶液是水。这是由于ZnO纳米棒的极性和非极性表面所预期的。(c)2006年，美国物理学会。
pH determination is a prerequisite for many biochemical and biological processes. The authors have used two methods, namely, the electrochemical potential method and the site binding method to study the sensitivity of zinc oxide (ZnO) nanorods for the use as intracellular pH sensing device. The dimensions of these nanorods were varied with radii between 50-300 nm and lengths between 2 and 10 mu m. The ZnO nanorods showed a high sensitivity approximate to 59 mV per decade at room temperature for a pH range (1-14), assuming that the solution is water. This is expected due to the polar and nonpolar surfaces of the ZnO nanorods. (c) 2006 American Institute of Physics.
