Characteristics and cellular uptake of tFNAs. a Structure of tFNAs. b Results of HPCE showing the successful assembly of tFNAs. c A TEM image showing the tFNA morphology. d Size of the tFNA molecule. e Zeta potential of the synthesized tFNAs. f Cy5-ssDNAs and Cy5-tFNAs taken up by HaCaT cells (Cy5-ssDNAs and Cy5-tFNAs: red; nucleus: blue; cytoskeleton:green). Scale bars are 100 pm. g Cy5-ssDNAs and Cy5-tFNAs taken up by HSF cells (Cy5-ssDNAs and Cy5-tFNAs: red; nucleus: blue; cytoskeleton:green). Scale bars are 100 pm
