Two kinds of dual-ligand targeting polymersomes, BT/FA-F127-PLA and (BT + FA)-F127-PLA, were prepared to study the effect of the dual-ligand distribution on the cell targeting of polymersomes. BT/FA-F127-PLA had two ligands distributed in the same polymersomes whereas (BT + FA)-F127-PLA had two ligands distributed in different polymersomes. The in vitro cytotoxicity and cellular uptake, and in vivo pharmacokinetic behaviors of BT/FA-F127-PLA were superior to those of (BT + FA)-F127-PLA. It suggested that biotin and folate ligands distributed on the same polymersomes could have the targeting effect of synergistic promotion. Further experiments on cell uptake mechanisms of polymersomes showed that the uptake of targeted polymersomes was associated with energy-dependent endocytosis, involving clathrin, caveolin protein, macropinocytosis and ligand receptor-mediated endocytosis. In addition, the effect of different density ratios of dual ligands for BT/FA-F127-PLA was further studied. The results showed that the cellular targeting effect of BT/FA-F127-PLA was the strongest when the molar ratio of biotin to folic acid was 7.5 %: 7.5 %.

Mechanical testing demonstrated that these MNs possess excellent mechanical strength, capable of withstanding at least 0.11 N per needle without rupture. In vitro drug penetration tests revealed that the MNs consistently released over 75 % of INS within a 6 h. In an animal model, ASMNs@PVP-INS reduced initial blood glucose levels from 22.4 to 5.72 mmol/L, effectively maintaining glucose control for more than 6 h without inducing hypoglycemia. Additionally, agar diffusion assays indicated that INS loading did not compromise the antimicrobial properties of antimicrobial sponge MNs (ASMNs). Skin irritation tests showed that ASMNs@PVP-INS exhibited mild irritation (PII < 0.6), with skin damage fully recovering within 8 h.

In this research, continuous twin-screw melt granulation was applied to improve the flowability of the fibers and therefore ease the further processing steps. During this work, two ASD compositions were investigated: one containing 60 % poly-vinylpyrrolidone-vinyl acetate 6:4 copolymer and 40 % itraconazole (ITR), and another one containing hydroxypropyl methylcellulose (HPMC) and ITR in the same ratio. Both fiber compositions were granulated with polyethene glycol as the binder material, while the effects of the process parameters were examined. The application of higher granulation temperature and screw configurations with increased shear forces compromised the fibrous structure, induced crystallization of the ASD, and decreased the dissolution. However, the stability of the ITR-HPMC fibers proved to be higher as their granulation at 60 °C led to granules with adequate flow properties and dissolution. Moreover, tablets with fewer excipients were pressed from them, resulting in a 34 % reduction in weight.
