    • Area-selective ZnO thin film deposition on variable microgap electrodes and their impact on UV sensing 

      Qazi Muhammad, Humayun; Muhammad Kashif, Muhammad Faroow; Uda, Hashim, Prof. Dr. (Hindawi Publishing Corporation, 2013)
      ZnO thin films were deposited on patterned gold electrodes using the sol-gel spin coating technique. Conventional photolithography process was used to obtain the variable microgaps of 30 and 43 μm in butterfly topology by ...

    • Fabrication of nanowire using ash trimming technique 

      Tijjani Adam, Shuwa; Uda, Hashim, Prof. Dr.; Leow, Pei Ling; Qazi Muhammad, Humayun (Trans Tech Publications, 2013)
      The paper present a report on fabrication of Nanowire using plasma oxidation, we monitor changes by studying the morphology and Δw/Δh, the study also revealed that the proposed fabrication method could potentially be used ...

    • Low cost detection of pH and its effect on the capacitive behavior of micro-gap sensor 

      Qazi Muhammad, Humayun; Uda, Hashim, Prof. Dr.; Tijjani Adam, Shuwa (Trans Tech Publications, 2014)
      The article describes the fabrication and characterization of silver microgap sensor on silicon substrate. By employing cheap photolithography process the proposed microgap sensor has been fabricated. The silver microgap ...

    • Nanobiosensor for the detection and quantification of pork adulteration in meatball formulation 

      Md. Eaqub, Ali, Dr.; Uda, Hashim, Prof. Dr.; Shuhaimi, Mustafa; Yaakob, Che Man; Tijjani Adam, Shuwa; Qazi Muhammad, Humayun (Taylor & Francis, 2014)
      A 27-nucleotide AluI fragment of swine cytochrome b (cytb) gene was integrated to 3-nm diameter citrate–tannate-coated gold nanoparticles to fabricate a species-specific nanobiosensor. The biosensor was applied to authenticate ...

    • Selective growth of ZnO nanorods on microgap electrodes and their applications in UV sensors 

      Qazi Muhammad, Humayun; Muhammad Kashif, Muhammad Faroow; Uda, Hashim, Prof. Dr.; Ahsanulhaq, Qurashi (Springer, 2014-01)
      Selective area growth of ZnO nanorods is accomplished on microgap electrodes (spacing of 6μm) by using a facile wet chemical etching process. The growth of ZnO nanorods on a selected area of microgap electrode is carried ...

    • ZnO thin film deposition on butterfly shaped electrodes for ultravioletsensing applications 

      Qazi Muhammad, Humayun; Muhammad Kashif, Muhammad Faroow; Uda, Hashim, Prof. Dr. (Elsevier GmbH, 2013-12)
      ZnO thin film was deposited on patterned gold electrodes using sol-gel spin coating technique. Conven-tional photo-lithography with wet etching process was used to create butterfly shaped 13-m gap fromzero gap chrome mask. ...
