Inchrosil Device (Picture: J.Rayon)

Inorganic Chromosome based in Silicon (InChroSil) is an electronic device, which has the same organization and structure of organic DNA (double helix), except for the chemical reactions. This device was developed using the standard technology Complementary metal–oxide–semiconductor (CMOS) and will be made in the nanometric scale, being the first inorganic DNA based in Silicon.

History

InChroSil was invented and patented in 2006 by two brothers and one Sister (Silvia, Carlos and Jose Daniel Llopis) in your house and few economics resources. The first prototype was a single nucleotide pair and had a size of a sheet of paper. Today it has developed and improved the Integrated circuit and can save billions of nucleotides and with a space-saving storage of 88 percent compared to the current genetic storage systems.

It is currently building prototypes in the clean room of Microsystems Technology Laboratories MTL of Massachusetts Institute of Technology MIT and staff Threellop Nanotechnology Inc (owner of industrial property (patent)).

Inchrosil characteristic

InChroSil allow us to store in less space, more genetic information (saving 88 percent). Current systems have a problem with the amount of information storage that organizations and institutions require. I.e. the human genome has approximately 3,000 million pairs of nucleotides, and is divided into 23 chromosomes. This information is too big for available systems, so currently only the principal chain is stored, meaning that holes within the DNA are not represented. With InChroSil, we offer less space and more information, with higher performance. We can store the entire structure of the DNA (principal and secondary chains), meaning InChroSil can store and represent even incomplete chains including the existent holes within the DNA chain.

This device uses non‐volatile digital memory, less storage space, is portable and allows for rewriting. It is also able to store non‐genetic information in the nucleotides (the basic elements of the DNA strand). The nucleotides can be used to represent genetic information, text, files, or even pictures in a more compact manner and with a wide range of device, hardware and software compatibility.

Uses to InChroSil

Inchrosil is used mostly for mass storage sequences DNA, with their uses:

• Fingerprinting staff, with the storage of the genetic fingerprint. His invention is Dr. Alec Jeffreys at the University of Leicester in 1984.
• Genetic studies, with the tool where large sequences would be stored, which could be compared and manipulated digitally.
• Genebanks, which store large amounts of genetic information.
• Classification of species and animals.
• Tool medical studies (genetic).
