REVERSING BIAS IN POLYMER SYNTHESIS ELECTRODE ARRAY
Polymers synthesized by solid-phase synthesis are selectively released from a solid support by reversing the bias of spatially addressable electrodes. Change in the current and voltage direction at one or more of the spatially addressable electrodes changes the ionic environment which triggers cleavage of linkers that leads to release of the attached polymers. The spatially addressable electrodes may be implemented as CMOS inverters embedded in an integrated circuit (IC). The IC may contain an array of many thousands of spatially addressable electrodes. Control circuity may independently reverse the bias on any of the individual electrodes in the array. This provides fine-grained control of which polymers are released from the solid support. Examples of polymers that may be synthesized on this type of array include oligonucleotides and peptides.
MOLECULAR LIBRARY ENCODING SYSTEM AND METHODS
The present invention provides methods and systems for encoding and decoding of synthesis steps and conditions of combinatorial synthesis of molecular library on carrier-beads. The encoding is performed at each step of synthesis by attachment of smaller fluorescently labelled beads (label-beads) to the surface of a carrier-bead (carrier-bead). The number of label-beads should be such that each is spatially resolvable on a surface of the carrier-bead. Alternatively label-beads are detachable, or the carrier-bead are dissolvable, so the label-beads could be dispersed over large enough distance to be resolved spatially. The fluorescent spectrum of each of the label-beads carries information of the synthesis step and synthesis, i.e., a spectral barcode or binary encoding system. During decoding of the spectrally identified label-beads, a fluorescent spectrum of each spatially resolvable label-bead is determined.
Selectively controllable cleavable linkers
Selectively controllable cleavable linkers include electrochemically-cleavable linkers, photolabile linkers, thermolabile linkers, chemically-labile linkers, and enzymatically-cleavable linkers. Selective cleavage of individual linkers may be controlled by changing local conditions. Local conditions may be changed by activating electrodes in proximity to the linkers, exposing the linkers to light, heating the linkers, or applying chemicals. Selective cleaving of enzymatically-cleavable linkers may be controlled by designing the sequences of different sets of the individual linkers to respond to different enzymes. Cleavable linkers may be used to attach polymers to a solid substrate. Selective cleavage of the linkers enables release of specific polymers from the solid substrate. Cleavable linkers may also be used to attach protecting groups to the ends of growing polymers. The protecting groups may be selectively removed by cleavage of the linkers to enable growth of specific polymers.

CONTROLLED PORE CERAMICS CHIPS FOR HIGH THROUGHPUT SOLID STATE OLIGONUCLEOTIDE SYNTHESIS
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.
