Multifunctional Hybridization Probes
Multicomponent (Multifunctional) Hybridization Probes/Sensors (MHPs) are nucleic acid detection systems in which two or more oligonucleotide strands assemble on a target to produce a signal, unlike conventional single-stranded hybridization probes. In an MHP, each component carries part of the recognition, binding, reporting or other function to achieve high selectivity, tightly bind nucleic acid analytes or produce detectable signals.
History and examples
Earlier examples of two-component hybridization probes use two fluorophore-labeled oligonucleotides that hybridize to the abutting positions of a nucleic acid analyte and produce Förster Resonance energy transfer (FRET) signal.[1] The idea was later commercialized as LightCycler technology.[2] This was followed by the introduction of a series of binary (split) probes for nucleic acid analysis.[3] In binary probes two components act in cooperation with each other to produce a detectable signal.[4]
Next step in conceptualization of MHPs was done in 2011 when in Molecular beacon (MB) probe-based MHP also known as X sensor named after DNA crossover structure was described.[5] In the X sensor, each strand (f and m) has two parts: one binds the MB probe, and the other binds the target nucleic acid (analyte). Strand f has a long analyte-binding arm that can unwind and strongly bind the analyte, while strand m has a short arm that forms a stable complex only with a perfectly matched target. The MB probe generates a fluorescent signal. Each component of the X sensor performs a distinct role but works cooperatively. This design enables the sensor to: (1) produce a fluorescent signal, (2) detect targets with high selectivity, and (3) tightly bind structured analytes like natural RNA.[6]
The MHP concept evolved into "DNA machines" for nucleic acid analysis, where some probe components were integrated into a single DNA nanostructure.[9] For example, in a DNAzyme (Dz)-based machine, Arms 1, 3 and 4 were linked to a common platform to cooperatively bind viral RNA, while Arm 2 provided high target selectivity.[10] The Dz core produces a fluorescent signal. A tile-associated hook delivered the fluorogenic substrate, greatly enhancing sensor sensitivity. This design highlights the value of a shared platform that unifies multiple components for coordinated action.[11]
