Deliver 302-79-4 MedChemExpress functionality as a drug delivery car. Lastly, the TRAP monomer has been shown to bind RNA [17] and, thus, the TRAP NT has the possible to function as a redox-sensitive delivery platform for RNA biomedicines which include RNAi, while this remains to be explored in detail.contaminants which will then be filtered out of a answer. TRAP subunits could also be mutated to lower the hydrophobicity of the outer surface and improve solubility on the nanotube just after assembly. In addition, sequestration of small molecules within the interior on the TRAP NT could give functionality as a drug delivery vehicle. Lastly, the TRAP monomer has been shown to bind RNA Biomedicines 2019, 7, 46 10 of 24 [17] and, thus, the TRAP NT has the potentiFigure 5.
