Deliver functionality as a drug delivery vehicle. Lastly, the TRAP monomer has been shown to bind RNA [17] and, as a result, the TRAP NT has the prospective to function as a redox-sensitive delivery platform for RNA biomedicines which include RNAi, even though this remains to be explored in detail.contaminants that can then be filtered out of a option. TRAP subunits could also be mutated to reduce the hydrophobicity of your outer surface and boost solubility on the nanotube following assembly. On top of that, sequestration of tiny molecules within the interior of the TRAP NT could offer 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, therefore, the TRAP NT has the potentiFigure five.
