There are two major challenges in the development of liposomal drug delivery systems for hydrophilic proteins: 1) low protein encapsulation efficiency, especially in the predominantly used small vesicle size range (50 150 nm); and 2) poor protein stability during preparation, especially if harsh processing conditions and/or organic solvents are involved. "Intelligent liposomes" are employed as an efficient drug carrier for the treatment of lung cancer . detected in the formulation over the initial concentration used to make the formulation. The encapsulation efficiency is evaluated by taking the centrifuged liposome's supernatant, and measured using UV-vis at 420 nm of wavelength. Niosomes, like liposomes, are vesicular systems that can encapsulate both hydrophilic and lipophilic drugs. 3. The ethanol injection method is an interesting technique for liposome production, due to its simplicity, fast implementation, and reproducibility. The extract was assayed by total flavonoid content (TFC), and was expressed as quercetin equivalence (QE) in propolis extract weight. Liposomal encapsulation technology (LET) is the newest delivery technique used by medical investigators to transmit drugs that act as curative promoters to the assured body organs. Enzymes, however, are fragile and encapsulation requires in addition the preservation of their functionality. Nii T, Ishii F. Source.
