    • Advances in biosensors: Principle, architecture and applications 

      Veeradasan, Perumal; Uda, Hashim, Prof. Dr. (Elsevier, 2014-01)
      The ability to detect pathogenic and physiologically relevant molecules in the body with high sensitivity and specificity offers a powerful opportunity in the early diagnosis and treatment of diseases. Early detection and ...

    • Fabrication and characterization of gold nano-gaps for ssDNA immobilization and hybridization detection 

      T.S., Dhahi; Uda, Hashim, Prof. Dr.; N.M., Ahmed; H., Nazma (Journal of New Materials for Electrochemical Systems, 2011)
      We develop a method for fabricating the nano-gaps directly by using just photolithography and wet etching processes without any nano lithography or difficult techniques. It shows that this resolution enhancement allows one ...
