Provide functionality as a drug delivery car. Lastly, the TRAP monomer has been shown to bind RNA [17] and, as a result, the TRAP NT has the potential to function as a redox-sensitive delivery platform for RNA biomedicines such as RNAi, despite the fact that this remains to be explored in detail.contaminants that can then be filtered out of a answer. TRAP subunits could also be mutated to lower the hydrophobicity with the outer surface and raise solubility of your nanotube just after assembly. On top of that, sequestration of tiny molecules inside the interior with 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 five.
