General description

Iodine is a halogen compound. It is mainly present in sodium iodate (NaIO3) and sodium periodate (NaIO4) deposits. Iodine is a part of thyroxin hormone produced by the thyroid gland. It controls the body′s rate of physical and mental development.

Application

Iodine (I2) was used in the following studies:
  • Synthesis of oligonucleotides using a standard Applied Biosystems 392 DNA/RNA Synthesizer.
  • Fabrication of electrochemical solar cells by using the single-walled carbon nanotubes (SWNTs)-modified fluorine-doped tin oxide coated glass (FTO) glass as the working electrode.
  • To compose iodide-based solution, used as the liquid electrolyte in the dye-sensitized solar cells.

It may be used for the trace-labelling of proteins. It may be used for the iodination methods, in which the cationic portion of the iodine molecule bounds to the ring structure of tyrosine. Theoretical efficiency of labelling achieved is 50%.

In this paper, we demonstrate in situ synthesis of oligonucleotide probes on poly(dimethylsiloxane) (PDMS) microchannels through use of conventional phosphoramidite chemistry. PDMS polymer was moulded into a series of microchannels using standard soft lithography (micro-moulding), with dimensions <100 microm. The
