摘要： Apparatus for fluorescent and ion sensing of DNA nucleotide incorporation events including DNA nucleotide incorporation structure designed to have sequencing primers bonded to a surface for the incorporation of DNA nucleotides thereon. At least some of the DNA nucleotides having a fluorescent label. A photodiode positioned adjacent the incorporation structure and an illumination device positioned adjacent the DNA nucleotide incorporation structure to illuminate DNA nucleotides incorporated onto the sequencing primers. The illumination device exciting the fluorescent labels when incorporation occurs and the photodiode positioned to sense the excited fluorescent labels. Ion sensing apparatus positioned adjacent the DNA nucleotide incorporation structure including a metal oxide thin film transistor with a gate electrically coupled to receive an electrical signal indicative of ion emissions produced by the DNA nucleotide incorporated onto DNA target fragments or sequencing primers.
