Preparation and characterizations of Bor/RB-M. A Synthetic route of Bor-PEG400-LA, B 1H NMR spectrum, and C HRMS analysis of Bor-PEG400-LA. D Particle size and PDI of Bor/RB-M with different feeding of Bor-PEG400-LA. E Size distribution of Bor/RB-M studied DLS. The left and right inserted pictures are Bor/RB-M solution and its TEM image. The bar is 100 nm F Zeta potential of the microemulsions. G EE of RH and BCL in RB-M and Bor/RB-M. H Stability of Bor/RB-M within 9 days. I Release profile of BCL and RH from Bor/RB-M within 24 h. All the data are shown as mean ± SD, n = 6
