Give functionality as a drug delivery car. Lastly, the TRAP monomer has been shown to bind RNA [17] and, thus, the TRAP NT has the prospective to function as a redox-sensitive delivery platform for RNA biomedicines which include RNAi, despite the fact that this remains to be explored in detail.contaminants that could then be filtered out of a remedy. TRAP subunits could also be mutated to lower the hydrophobicity with the outer surface and raise solubility from the nanotube immediately after assembly. On top of that, sequestration of small molecules within the interior with the TRAP NT could deliver functionality as a drug delivery car. Lastly, the TRAP monomer has been shown to bind RNA Biomedicines 2019, 7, 46 10 of 24 [17] and, hence, the TRAP NT has the potentiFigure 5.
