Give functionality as a drug delivery automobile. Lastly, the TRAP monomer has been shown to bind RNA [17] and, therefore, the TRAP NT has the potential to function as a redox-sensitive delivery platform for RNA biomedicines like RNAi, despite the fact that this remains to become explored in detail.contaminants that can then be filtered out of a solution. TRAP subunits could also be mutated to decrease the hydrophobicity of your outer surface and improve solubility in the nanotube following assembly. On top of that, sequestration of smaller molecules inside 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 ten of 24 [17] and, hence, the TRAP NT has the potentiFigure 5.
