A synthesis device comprises a plurality of pipes, a feeding unit, a reaction vessel, and a measurement mechanism. The pipes extend from a plurality of storage containers, respectively, in which a plurality of types of solutions are stored. The feeding unit is configured to feed the solutions in the storage containers through the pipes. The solutions selectively fed from the storage containers are put in the reaction vessel to generate a synthesized product by chemical synthesis. The measuring mechanism is provided between the storage containers and the reaction vessel in a middle of an overall flow path including the pipes, the measuring mechanism being configured to measure the solutions fed to the reaction vessel.

A nano-structured ceramic film with controlled pore size for the high throughput synthesis of oligonucleotides (DNA and RNA). The film can be cut into chips of predetermined size, and code printed for optical recognition in automated DNA synthesizers. The chips are easily activated under very mild conditions and silanization proceeds uniformly to allow reagents to flow unhindered through its open pores. Mono layer modifications, such as covalently bound silane coupling agents, allows for the addition of universal linkers and improved yields compared to conventional approaches.

Nucleic acid memory strands encoding digital data using a sequence of homopolymer tracts of repeated nucleotides provides a cheaper and faster alternative to conventional digital DNA storage techniques. The use of homopolymer tracts allows for lower fidelity, high throughput sequencing techniques such as nanopore sequencing to read data encoded in the memory strands. Specialized synthesis techniques allow for synthesis of long memory strands capable of encoding large volumes of data despite the reduced data density afforded by homopolymer tracts as compared to conventional single nucleotide sequences.

A method of synthesizing an oligonucleotide using a nanofluidic device including a plurality of nanopore channels, a plurality of electrodes, and an electrolyte solution, includes coupling a primer to an inner wall of a nanopore channel of the plurality of nanopore channels, the primer having a protecting group.
