    • Application of gold nanoparticles for electrochemical DNA biosensor 

      Ahmed Mishaal, Mohammed; Ruslinda, Abdul Rahim, Dr.; Ibraheem Jaleel, Ibraheem; Foo, Kai Loong; Hasrul Hisham, Che Ahmad; Uda, Hashim, Prof. Dr.; Yarub, Al-Douri, Assoc. Prof. Dr. (Hindawi Publishing Corporation, 2014)
      An electrochemical DNA biosensor was successfully fabricated by using (3-aminopropyl)triethoxysilane (APTES) as a linker molecule combined with the gold nanoparticles (GNPs) on thermally oxidized SiOthin films. The SiOthin ...

    • Gold nanoparticle sensor for the visual detection of pork adulteration in meatball formulation 

      Md Eaqub, Ali; Uda, Hashim, Prof. Dr.; Shuhaimi, Mustafa, Assoc. Prof. Dr.; Yaakob, Che Man, Prof. Datuk Dr.; Kh. N. Islam (Hindawi Publishing Corporation, 2012)
      We visually identify pork adulteration in beef and chicken meatball preparations using 20 nm gold nanoparticles (GNPs) as colorimetric sensors. Meatball is a popular food in certain Asian and European countries. Verification ...

    • Nanoparticle sensor for label free detection of swine DNA in mixed biological samples 

      M. E., Ali; Uda, Hashim, Prof. Dr.; S., Mustafa; Y. B., Che Man; M. H. M., Yusop; Mohd Fazalul, Bari; Kh. N., Islam; M. F., Hasan (IOP Publishing Ltd., 2011-05-13)
      We used 40 5nm gold nanoparticles (GNPs) as colorimetric sensor to visually detect swine-specific conserved sequence and nucleotide mismatch in PCR-amplified and non-amplified mitochondrial DNA mixtures to authenticate ...
