Deliver functionality as a drug delivery automobile. Lastly, the TRAP monomer has been shown to bind RNA [17] and, therefore, the TRAP NT has the possible to function as a redox-sensitive delivery platform for RNA biomedicines including RNAi, while this remains to be explored in detail.contaminants that could then be filtered out of a resolution. TRAP subunits could also be mutated to lower the hydrophobicity from the outer surface and increase solubility with the nanotube soon after assembly. Moreover, sequestration of modest molecules inside the interior in the TRAP NT could give functionality as a drug delivery automobile. Lastly, the TRAP monomer has been shown to bind RNA Biomedicines 2019, 7, 46 ten of 24 [17] and, for that reason, the TRAP NT has the potentiFigure 5.
