“…ZnO NRs with controlled shape and order could be grown by thermal vapor deposition (TVD) (Huang et al, 2001b;Giri et al, 2010;Li et al, 2008;Yao et al, 2002), metal-organic chemical vapor deposition (Yuan & Zhang, 2004;Park et al, 2002;Kim et al, 2009), molecular beam epitaxy (Heo et al, 2002), hydrothermal/solvothermal methods (Breedon et al, 2009;Verges et al, 1990;Alvi et al, 2010;Tak & Yong, 2005;Pacholski et al, 2002;Song & Lim, 2007) and top down approach by etching (Wu et al, 2004). Among those techniques, vapor deposition and chemical methods are the widely used techniques for their versatility about controllability, repeatability, quality and mass production.…”

“…A mixture of 30 mM NaOH solution in methanol and 10 mM zinc acetate dehydrate in methanol was used as a seed solution for the ZnO nanorods under stirring at 60°C for 2 hours. This seed solution was spincoated onto a Ag/Ti/PES substrate at 1000 rpm for 30 s. The uniformity and density of the ZnO seed layer on the substrate depend on the spin-coating speed and time [10], [11]. Also, the density of ZnO nanorods depends on the density of ZnO seed layer [11].…”

-This paper describes the power generating property of hydrothermally grown ZnO nanorods on a flexible polyethersulfone (PES) substrate. The piezoelectric currents generated by the ZnO nanorods were measured when bending the ZnO nanorod by using I-AFM, and the measured piezoelectric currents ranged from 60 to 100 pA. When the PtIr coated tip bends a ZnO nanorod, piezoelectrical asymmetric potential is created on the nanorod surface. The Schottky barrier at the ZnO-metal interface accumulates elecntrons and then release very quickly generating the currents when the tip moves from tensile to compressed part of ZnO nanorod. These ZnO nanorods were grown almost vertically with the length of 300-500 nm and the diameter of 30-60 nm on the Ag/Ti/PES substrate at 90°C for 6 hours by hydrothermal method. The metal-semiconductor interface property was evaluated by using a HP 4145B Semiconductor Parameter Analyzer and the piezoelectric effect of the ZnO nanorods were evaluated by using an I-AFM. From the measured I-V characteristics, it was observed that ZnO-Ag and ZnO-Au metal-semiconductor interfaces showed an ohmic and a Schottky contact characteristics, respectively. ANSYS finite element simulation was performed in order to understand the power generation mechanism of the ZnO nanorods under applied external stress theoretically.

Abstract. Blood typing is a critical test in many medical procedures, especially for blood transfusion. Incompatible red blood cells (RBCs) in transfusion might result in intravascular hemolysis and even cause recipients death. The test result of blood typing can be determined by observing the agglutination of RBCs. In this study, a microfluidic blood typing chip with interdigitated electrodes is presented. ZnO nanowires were synthesized on the interdigitated electrodes so that voltammetry measurement was employed to determine the test results of blood typing. The experimental results show that the discrimination between agglutination and non-agglutination was obvious and successful determinations of RBC agglutinations in blood typing tests were achieved by means of voltammetry measurement.
