Deliver functionality as a drug delivery car. Lastly, the TRAP monomer has been shown to bind RNA [17] and, thus, the TRAP NT has the potential to function as a redox-sensitive delivery platform for RNA biomedicines for instance RNAi, while this remains to become explored in detail.contaminants that may then be filtered out of a option. TRAP subunits could also be mutated to reduce the hydrophobicity of the outer surface and improve solubility from the nanotube following assembly. Furthermore, sequestration of smaller molecules within the interior from 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 ten of 24 [17] and, thus, the TRAP NT has the potentiFigure 5.
