Synthesis and analysis of DT and S3-DT. A Four single-stranded DNA fragments formed a regular tetrahedral structure (pyramid shape) through complementary pairing. B Gel electrophoresis was utilized to detect the molecular sizes of A chain, A + B chain, A + B + C chain, DT, and S3-DT. C The particle size of DT was 14.23 ± 3.79 nm, and that of S3-DT was 23.02 ± 6.54 nm. D DT or S3-DT was incubated in a complete medium for 0–24 h and then detected by gel electrophoresis. E DT or S3-DT was incubated in 1:1 FBS for 0–7 h and then detected by gel electrophoresis. The experiments were repeated thrice
