Webb26 jan. 2024 · Aptamer switches are attractive nature-inspired tools for developing smart materials and nanodevices. However, the thermal robustness and programmability of current aptamer switches are often … WebbThe basic mechanism of action is that an RNA molecule with a complementary sequence to that of the switch region of the toehold switch binds to the switch and causes the structure to open up, removing the toehold structure and revealing the RBS to allow the ribosome to bind. This mechanism is discussed in further detail below. Green et al. 2014:

WebbThe Design. Toehold switches contain multiple parts, namely: the trigger binding site, the ribosome binding site (RBS), the seven amino acid long linker sequence and the protein coding sequence. The trigger binding site on each toehold switch is the reverse complement to the trigger RNA strand. As the miRNAs are both 22 nucleotides long, the ... Webb27 jan. 2024 · Notably, for both MERS-CoV and SARS-CoV-2 target RNA, we detected as few as 120 copies per reaction (12 copies/μL, 20 aM), the highest sensitivity reported using a toehold switch sensor. When NASBA was used as an amplification step for the toehold reaction, the detection limit was 3 fM of Zika viral RNA [ 12 ].
