Because of chemical behaviors of real DNA molecules, the nanotechnology envisioned by the Defense Department in this Solicitation will be possible only if design automation software creates nanostructures that exploit artificially expanded genetic information systems (AEGIS). AEGIS DNA molecules have more than the four nucleotides (GACT) found in natural DNA. In Phase 1, we delivered a demonstration project showing that adding nucleotides to standard DNA supports three-dimensional self-assembling nanoarchitectures at the frontier of the field. We also improved several of the AEGIS components. This progress will allow Phase 2 to deliver kits for specialists, non-specialists, and students that combine AEGIS DNA with non-DNA linkers to give a nano AEGIS"Lego"kit. We will also deliver a nanostructure as a signaling element to detect DNA from insect-borne pathogens that cause rickettsial diseases (e.g. typhus). This project overlaps Firebird's business, which supports human diagnostics based on reagent innovations like AEGIS. Adding nanotechnology to its existing business makes commercial sense, and will help"dual uses"emerge from this project.

Because of chemical behaviors of real DNA molecules, the nanotechnology envisioned by the Defense Department in this Solicitation will be possible only if design automation software creates nanostructures that exploit artificially expanded genetic information systems (AEGIS). AEGIS DNA molecules have more than the four nucleotides (GACT) found in natural DNA. Our software will accommodate nanoarchitectures built from these four, plus eight additional orthogonally pairing AEGIS nucleotides. By evading the computational challenges associated with natural DNA nanostructures, AEGIS will allow delivery at the end of Phase I, ahead of schedule, software that helps nanotechnologists design nanostructures that incorporate binding and catalytic DNA molecules, sensing functionality, and optical signaling elements. Additional benefits of AEGIS DNA nanostructures are their enhanced stability and potential to support continuous environmental monitoring. Also ahead of schedule, our Phase I work will deliver a physical example of a nanostructure containing these functional elements. This will allow Phase II to focus on higher level nanostructure performance, including dynamic architectures, interfaces to electrical output, and amorphous computing. This project overlaps Firebird's business, which supports human diagnostics based on reagent innovations like AEGIS. Adding nanotechnology to its existing business makes commercial sense, and will help"dual uses"emerge from this project.

Firebird will deliver a hand-held CLIA-waivable battery-powered device that will allow point-of-need detection of norovirus RNA, with a fluorescence readout excited by a battery-powered LED. The readout can be interpreted at the point-of-need, or transmitted by cell phone to a distant site. This devise is possible only through the application of five technologies to which Firebird has exclusive access: (a) Artificially expanded genetic information systems (AEGIS), which allow low-noise amplification of DNA and RNA (collectively xNA) from a sample; (b) self-avoiding molecular recognition systems (SAMRS), which allow introduction of multiple primers and probes to give highly multiplexed and highly flexible xNA-targeted assays; (c) isothermal xNA amplification architectures using helicase-dependent amplification (HDA), which allows xNA to be targeted without the thermocycling needed for PCR (PCR will not be forward-deployed by the Army); (d) AEGIS beacons, which allow signal readout without interference from competing natural xNA, allowing ?soup-to-nuts assays? without sample maniputations any more complicated than mixing; (e) The StrainTargeter bioinformatics platform, which supports the design of xNA-targeted assays for viruses (such as the norovirus) that are rapidly adapting. In Phase 1, the reagent support will be developed, with the Option period devoted to testing on Trisol inactivated norovirus samples.

Firebird will deliver multiplexed assays that inexpensively detect and distinguish coccidioidomycosis, blastomycosis, and histoplasmosis by targeting the genomic DNA of their causative agents. This assay uses six Firebird technologies: 1. Artificially expanded genetic information systems (AEGIS), which support ultra-clean DNA amplification with ultra-low noise despite the complexity of realbiological samples. 2. Self-avoiding molecular recognition systems (SAMRS), which permit unlimited multiplexing of xNA targeted assays, and (consequently) low cost and extreme adaptability in such assays. 3. Conversion technologies that create AEGIS-containing amplicons easily detected by Luminex without interference from any naturally found xNA. 4. Evolution-based software to select genomic targets for genus and species discrimination. 5. Novel reagent-enzyme combinations that make fungal xNA accessible to amplification. 6. Novel isothermal amplification methods to allow the assays to work near points-of-care. The initial product will address the interest of the NCEZID in analyzing environmental samples, to avoid costly FDA regulation. Firebird's investment in pipelines allows us to prepare AEGIS and SAMRS building blocks in multi-gram amounts, and their oligonucleotides on demand. Thus, this product fits well within Firebird's current product line. Specific diagnosis of fungal infections will enhance public health by providing a mechanism to save lives and prevent death serious disease.
