METHODS AND SYSTEMS FOR PROCESSING A BIOLOGICAL SAMPLECROSS-REFERENCE
[0001] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 670,623 filed on July 12, 2024, which is incorporated by reference in its entirety.BACKGROUND
[0002] Rapid and accurate molecular diagnosis is critical for timely detection and treatment of infectious human or agricultural pathogens. Molecular Diagnostic (Dx) technologies typically involve nucleic acid amplification and detection by expensive, sophisticated equipment such as quantitative PCR (qPCR), which cannot be deployed in field or true point-of-care (PoC) scenarios, leading to delays in diagnosis and treatment. Recent pandemics have highlighted the necessity of instrument-free, cost-effective molecular Dx technologies that can be used by anyone, deployed anywhere and easily configured for any disease target. The gold standard amplification technology, PCR, requires specialized thermocycling equipment, trained (skilled) technical operators, and stringent experiment design, among other constraints. Unlike PCR, existing isothermal amplification technologies, such as LAMP, HAD, or RPA do not require a thermocycler, but still require an incubator for maintaining a constant elevated temperature. Additionally, these methods have specific design constraints, are prone to non-specific amplification which can inhibit specificity and sensitivity of detection, and cannot easily differentiate single nucleotide mismatches in target sequences. Therefore, these methods require an additional enzymatic technology for specific and sensitive detection at PoC, such as CRISPR / Cas-based SHERLOCK and DETECTR technologies. Consequently, these methods increase total detection time, manufacturing costs, and assay design complexity. There is also a current lack of effective near PON diagnostic tests utilizing real-time detection designed for very high-throughput, with little training required or medium training involved, which can be operated at a low-medium cost with medium-high sensitivity and very high specificity in small clinical labs. Recognized herein is a need for technical solutions to address these hurdles in the field.
[0003] Furthermore, nucleic acid testing (NAT) biosensing technologies, such as those employing the use of fluorophores or redox sensors, or other physicochemical detectors, are currently used in numerous applications for the detection of nucleic acids (NA) of a particular pathogen or mutated genes in an organism. NATs use the specificity and sensitivity afforded by nucleic acid base pairing to detect different NA sequences, sometimes differing by asingle nucleotide. However, for a NAT to work effectively, the detectable target sequence for the probe sequence needs to be single-stranded DNA and / or RNA. This allows for a probe having a physicochemical detector (e.g., a genosensor probe) to hybridize to its complementary sequence, which is usually a single-stranded DNA and / or RNA target.
[0004] The most used nucleic acid amplification test (NAAT) is PCR which remains the gold standard of current diagnostics. However, PCR is difficult to conduct in a point-of-need setting because of the requirement of specific cycling temperatures: for example, (i) a very high temperature (usually 95°C) required for thermal melting of dsDNA / dsRNA (either the starting sequence or the amplicons after the first amplification cycle), (ii) annealing temperature (usually between 50-70°C) for the primers to bind to, and (iii) the extension temperature for the corresponding amplification by the common polymerases (e.g., Taq (72°C)). Additionally, PCR and real-time PCR are limited to the time required for each cycle, thereby increasing the total time of the reactions. Other isothermal NAATs, such as LAMP (loop-mediated isothermal amplification), HDA (helicase-dependent isothermal DNA amplification), SDA (strand displacement amplification), NASBA (nucleic acid sequencebased amplification), RCA (rolling circle amplification), can amplify DNA or RNA in a simpler setting by avoiding the need for a cycling method. However, all the aforementioned methods still require either thermal melting of the dsDNA or dsRNA, incubation at a temperature higher than 50°C, or require the addition of finicky nucleases adding to the complexity of the process.
[0005] Additionally, most NAATs can amplify if there is contamination or are prone to primer artefact generation, and therefore nested amplification strategies or primer modifications are utilized to make the amplicon results more specific. Furthermore, most NAATs utilize a dual-strand amplification strategy to increase the number of copies exponentially. However, this results in dsDNA amplicons, which may need to be denatured before being detected by a hybridization probe sequence. While asymmetric amplification strategies can be used to amplify mostly single-stranded DNA, it heavily limits the amplification rate to a linear rate instead of the exponential rate of the dual-strand approach. While there are additional probe design strategies which rely on specific modifications in the probe or the addition of another enzyme to facilitate a change in probe structure or sequence, most of these methods can complicate the amplification design strategy or result in probe artefact generation. Recognized herein is a need for technical solutions that address these technical problems in the field.SUMMARY
