MODIFIED BNC FOR CHIP CARDS AND MEDICINE
Bacterial nanocellulose (BNC) is a renewable,environmentallyfriendlymaterialthat has many advan- tageous properties, like a pure fiber network structure, a high degree of polymerization, a high mecha- nical strength, a great water holding capacity and biocompatibility. Therefore BNC attracts attention in variousapplicationfields. Here a BNC, which was modifiedwithlight-gatedDNA-Polymerases, other lightgated-proteinsand DNAis described, which can be applied in two fields:
modified BNC as a nanocellulose chip technology for data storage (Nanocellulose Chip) modified BNC as a optoelectronic device for wound monitoring and tissue engineering
Modified BNC as a nanocellulose chip technology for data storage
The emerging technology uses nanocellulose as a matrix for the new chip. Thereby text, image and sound information are encoded into DNA using light-gated polymerases. The read-out uses fluore- scent exonucleases. Light allows ultrafast substrate change (for read-in) and specific addressing of informationstored in the nanocellulose chip matrix, while light-gated proteins, specific promotor and terminator sequences enhance storage and processing further. Light-sensitive nano-pores control elec- tronic properties. Further interfaces to silicon computers use fluorescent proteins. The technology has many advantages:
the potential of ultrahigh density data storage (Billions of Gigabyte) embedding DNA ultrafast (million times faster than conventional computer chip) information processing of the nanocellulose embedded DNA use of light and light-gated proteins instead of electronics safe data storage for many thousands of years.
Modified BNC as a optoelectronic wearable for wound monitoring
The emerging technology uses nanocellulose as a matrix for a tissue repair plaster. Light-gated proteins are embedded and can displaythewoundcondition. Light-induced releaseofgrowth-factorsor phar- maceuticalscan support and accelerate wound healing.
The novel chip technology can be used as a novel data storage system, as a computer chip or a weara- ble for wound healing.
