Present functionality as a drug delivery vehicle. Lastly, the TRAP monomer has been shown to bind RNA [17] and, hence, the TRAP NT has the potential to function as a redox-sensitive delivery platform for RNA biomedicines which include RNAi, although this remains to be explored in detail.contaminants that may then be filtered out of a remedy. TRAP subunits could also be mutated to decrease the hydrophobicity of the outer surface and improve solubility from the nanotube right after assembly. On top of that, sequestration of smaller molecules within the interior in the TRAP NT could deliver functionality as a drug delivery vehicle. Lastly, the TRAP monomer has been shown to bind RNA Biomedicines 2019, 7, 46 10 of 24 [17] and, for that reason, the TRAP NT has the potentiFigure 5.
