Blank PLGA and CIP-loaded PLGA NP (PLGA/CIP NP) were prepared by employing the nanoprecipitation methodology, as previously described by Günday et al. [52 ]. In brief, the solvent system (consisting of 0.4 % (w/v) PLGA and 0.15 % (w/v) Span 80® solution in acetone, mixed with 4.85 % CIP solution in oleic acid) and the non-solvent system (0.15 % (w/v) aqueous Tween 80 solution) were nanoprecipitated continuously at a 1:2 ratio and an angle of 180° under ambient conditions. In case of the labelled NP preparation, 1.12 × 10⁻⁴ % (w/v) Lumogen F Red 305® (BASF, Germany) was introduced into the solvent system. The purification process, involving the removal of free formulation components and organic solvent, as well as the concentration of the formulation to achieve the desired CIP concentration, was achieved through continuous flow filtration using modified polyethersulfone MidiKros® hollow fiber filters (MWCO: 10 kDa, surface area: 235 cm²; Spectrum, Repligen Europe B.V., Netherlands).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
