Polymetric NPs containing both JO and PTX (NPs/PTX-JO) and NPs lacking JO (NPs/PTX) were prepared by (low MW)-surfactant-free nanoprecipitation [28 (link)]. Different amounts of JO (1.5, 4.8, 9.6, and 19.2 μL) were dissolved in 0.8 mL acetonitrile (ACN) containing 70 μM PP and 14 μM PTX. Thereafter, ACN was added dropwise into ultrapure water (Biological Industries, Kibbutz Beit-HaEmek, Israel), and stirred at room temperature to obtain NPs with different PTX:JO molar ratios of 1:0.16 (1:1 w/w [29 (link)]),1:0.5, 1:1, and 1:2, respectively. S15-APTs were covalently conjugated to the NPs as previously described [14 (link)].
