Platforms for Bioorthogonal Oligonucleotide-templated Reactions: Translating Concepts into Devices
Keywords:Oligonucleotide-templated reaction, Sensing, Hydrogel, Diagnostic, Paper-microfluidic
AbstractThe exponential improvements made in DNA sequencing technologies, together with the rapidly declining associated costs, has increasingly led to the expansion of the field of personalised genomic medicine. Changes in the sequence or copy number of specific deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) molecules represent key signatures for the diagnosis, prognosis, classification and monitoring of a broad range of pathologies, most notably cancer. Technologies that can detect these changes require analytical tools that can detect DNA or RNA with high sensitivity and high specificity. Sensing based on bioorthogonal oligonucleotide-templated reactions (OTRs) has been recognised as an elegant strategy that satisfies these criteria and was successfully used for the quantitative detection of nucleic acids both in vitro and in vivo. Herein, we will focus on recent efforts to implement bioorthogonal OTRs into clinically useful biosensors using probes immobilised on or embedded in customised materials and platforms.
