Abstract: Provided herein are imaging probes and systems and methods employing such imaging probes for real-time, label-free, multiplexed imaging of RNAs in living cells. More particularly, aptamer-based sensors (“aptasensors”) and molecular fuses comprising multiple aptasensors are genetically encoded imaging probes comprising RNA-target binding sequence and an intramolecular reconfiguration sequence. The probe is configured such that binding of a RNA target by the RNA-target binding sequence triggers the intramolecular reconfiguration sequence to reconfigure such that an optically detectable output is generated by the probe.

Abstract: The present disclosure describes methods, devices, reagents, and kits for the detection of one or more target molecules that may be present in a test sample. The described methods, devices, kits, and reagents facilitate the detection and quantification of a non-nucleic acid target (e.g., a protein target) in a test sample by detecting and quantifying a nucleic acid (i.e., an aptamer) where the aptamer-aptamer interactions are significantly reduced or eliminated while maintaining the aptamer-target interaction.

Abstract: The present disclosure describes improved SELEX methods for producing aptamers that are capable of binding to target molecules and improved photoSELEX methods for producing photoreactive aptamers that are capable of both binding and covalently crosslinking to target molecules. Specifically, the present disclosure describes methods for producing aptamers and photoaptamers having slower dissociation rate constants than are obtained using prior SELEX and photoSELEX methods. The disclosure further describes aptamers and photoaptamers having slower dissociation rate constants than those obtained using prior methods. In addition, the disclosure describes aptamer constructs that include a variety of functionalities, including a cleavable element, a detection element, and a capture or immobilization element.

Abstract: An object of the present invention is to develop and provide a method for efficiently producing a nucleic acid aptamer, particularly, a DNA aptamer, having higher specificity and binding activity against a target substance than those of nucleic acid aptamers obtained by conventional methods. The present invention provides a transcribable or replicable nucleic acid aptamer comprising a natural nucleotide and a non-natural nucleotide having an artificial base-pairable artificial base. The present invention also provides a method for sequencing a non-natural nucleotide-containing single-stranded nucleic acid molecule selected from a single-stranded nucleic acid library.

Abstract: This invention relates to methods for molecular detection, particularly to methods utilizing target-specific molecular probes. In exemplary embodiments, target-specific molecular probes include single-stranded deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) aptamers. In general, the molecular probe may bind with relatively high specificity to a given target. In one aspect, a method for molecular detection comprises a molecular probe paired to a reporter molecule wherein the molecular probe impairs the amplification of the reporter molecule in the absence of the target molecule.
