abstract = {Liposomes, due to their mimetic cellular composition, are gaining great attention as release systems for lipophilic and hydrophilic molecules. However, liposomes can present a high tendency to degrade and aggregate into biological fluids and under storage conditions. To overcome these limitations, in this work, a stabilizing strategy consisting in liposomes incorporation into polymeric granules was studied. Wet granulation was adopted to produce granules of hydroxypropyl methylcellulose (HPMC) and liposomal suspensions were used as the binder phase. In particular, in this study, three different percentages of liposome load in HPMC granules were investigated (1%, 5% and 10% w/w) focusing the attention on several relevant technological characteristics of the achieved solid particulates: size, flow index, mechanical strength (granules without liposomal inclusions were used as a control). Morphological observations (by TEM) confirmed the presence of intact liposomes in dry HPMC granules; moreover, it was found that the binder phase with the lower liposome concentrations (1%, 5%) did not significantly affect size, flowability and hardness of the lipid-polymer granules. Instead, the granules containing the highest percentage of liposomes (10% w/w) have larger dimensions, harder structure and reduced flowability. Therefore, the followed process strategy, under liposomal concentration restrictions, allowed to obtain both the liposomes stabilization, a not trivial technological issue, and the production of particulates with good solid state properties, useful as a versatile dosage form (lipid carriers in polymer carriers).},

After an evaluation of its fluid dynamic nature, the simil-microfluidic (SMF) apparatus was first used to study the effects of the adopted process parameters on vesicles dimensional features by using ultrasonic energy to enhance liposomes homogenization. Subsequently, iron-nanoliposomes were produced at different weight ratios of ferrous sulfate to the total formulation components (0.06, 0.035, 0.02, and 0.01 w/w) achieving, by using the 0.01 w/w, vesicles of about 80 nm, with an encapsulation efficiency higher than 97%, an optimal short- and long-term stability, and an excellent bioavailability in Caco-2 cell line. Moreover, a comparison realized between the SMF method and two more conventional production techniques showed that by using the SMF setup the process time was drastically reduced, and the process yield increased, achieving a massive nanoliposomes production. Finally, duty-cycle sonication was detected to be a scalable technique for vesicles homogenization. },

In this context, nanoliposomes have had a great impact in topical preparations and dermocosmetics, allowing the transcutaneous penetration and absorption of several active ingredients and improving the stability of sensitive molecules. Despite the recent boom of this class of delivery systems, their industrial production is still limited by the lack of easily scalable production techniques. In this work, nanoliposomes for the topical administration of vitamin D3, K2, E, and curcumin, molecules with high antioxidant and skin curative properties but unstable and poorly absorbable, were produced through a novel simil-microfluidic technique. The developed high-yield semi continuous method is proposed as an alternative to face the problems linked with low productive conventional methods in order to produce antioxidant formulations with improved features. The novel technique has allowed to obtain a massive production of stable antioxidant vesicles of an 84–145 nm size range, negatively charged, and characterized by high loads and encapsulation efficiencies. The obtained products as well as the developed high-performance technology make the achieved formulations very interesting for potential topical applications in the cosmetics/cosmeceutical field. },

To improve their stability, permeability, and some specific surface properties, such as mucoadhesiveness, these structures can require a process of surface engineering. The interaction of lipid vesicles with oppositely charged polyelectrolytes seems to be an interesting solution, especially when the negatively charged liposomes are complexed with the cationic chitosan. In this work, a novel simil-microfluidic technique was used to produce both chitosan-coated vesicles and a vegan alternative composed of cholesterol-free liposomes coated by Guar Hydroxypropyltrimonium Chloride (Guar-HC). The combination between the experimental approach, based on experimental observations in terms of Z-potential, and size evolutions, and the theoretical approach, based on concepts of saturation, was the methodology applied to define the best polycation concentration to fairly cover (vegan or not) liposomes without aggregation. The smart production of coated nanolipid structures was confirmed by characterizations of morphology, mucoadhesiveness, and stability.},

The growth of such powerful biologic therapeutics has gone hand in hand with the progress in delivery systems technology, which is absolutely required to improve their safety and effectiveness. Lipid carrier systems, particularly liposomes, have been proven to be the most suitable vehicles meeting NABDs requirements in the medical healthcare framework, limiting their toxicity, and ensuring their delivery and expression into the target tissues. In this review, after a description of the several kinds of liposomes structures and formulations used for in vitro or in vivo NABDs delivery, the broad range of siRNA-liposomes production techniques are discussed in the light of the latest technological progresses. Then, the current status of siRNA-lipid delivery systems in clinical trials is addressed, offering an updated overview on the clinical goals and the next challenges of this new class of therapeutics which will soon replace traditional drugs},

abstract = {Liposomes constitute a class of prominent drug delivery systems due their cell-mimetic behaviour. Despite
their high biocompatibility, biodegradability and low intrinsic toxicity, their poor stability in biological fluids
as well as in stock conditions (high tendency to degrade or aggregate) have led to new approaches for
liposome stabilization (e.g., surface covering with polymers). Here, liposomes were enwrapped by the
natural biocompatible polymer chitosan to achieve stable shell–core nanostructures. Covered
nanoliposomes were produced using an innovative continuous method based on microfluidic principles.
The produced hybrid polymeric-lipid nanoparticles were characterized in terms of structural properties,
size and stability. Moreover, phenomenological aspects in formation of nanoliposomal vesicles and
chitosan layering, product quality (structure, size) and manufacturing yield related to this novel method
were compared with those of the conventional dropwise method and the obtained products. The
proposed simil-microfluidic method led to the production of stable and completely chitosan-covered
liposomes with a shell–core nanostructure that avoided the disadvantages inherent in the conventional
method (which are time-consuming and/or require bulky and more expensive equipment).},

abstract = {Non-steroidal anti-inflammatory drugs (NSAIDs), i.e. indomethacin used for rheumatoid arthritis and non-rheumatoid inflammatory diseases, are known for their injurious actions on the gastrointestinal (GI) tract. Mucosal damage can be avoided by using nanoscale systems composed by a combination of liposomes and biodegradable natural polymer, i.e. chitosan, for enhancing drug activity.

Aim of this study was to prepare chitosan-lipid hybrid delivery systems for indomethacin dosage through a novel continuous method based on microfluidic principles. The drop-wise conventional method was also applied in order to investigate the effect of the two polymeric coverage processes on the nanostructures features and their interactions with indomethacin. Thermal-physical properties, mucoadhesiveness, drug entrapment efficiency, in vitro release behavior in simulated GI fluids and stability in stocking conditions were assayed and compared, respectively, for the uncoated and chitosan-coated nanoliposomes prepared by the two introduced methods.

The prepared chitosan-lipid hybrid structures, with nanometric size, have shown high indomethacin loading (about 10%) and drug encapsulation efficiency up to 99%. TEM investigation has highlighted that the developed novel simil-microfluidic method is able to put a polymeric layer, surrounding indomethacin loaded nanoliposomes, thicker and smoother than that achievable by the drop-wise method, improving their storage stability. Finally, double pH tests have confirmed that the chitosan-lipid hybrid nanostructures have a gastro retentive behavior in simulated gastric and intestinal fluids thus can be used as delivery systems for the oral-controlled release of indomethacin.

Based on the present results, the simil-microfluidic method, working with large volumes, in a rapid manner, without the use of drastic conditions and with a precise control over the covering process, seems to be the most promising method for the production of suitable indomethacin delivery system, with a great potential in industrial manufacturing.},

The protocol basically consists in the realization of a contact between two flows, lipids/ethanol and water solutions, inside a tubular device where interdiffusion phenomena allow the formation of lipid vesicles. Effects of solutions flow rates and lipids concentrations on size and size distribution have been investigated. Moreover, ultrasonic energy was used to enhance homogenization of the hydroalcoholic final solutions and to promote the vesicles size reduction. By this protocol a massive output has been achieved; increasing the ratio between the water volumetric flow rate to the lipids-ethanol volumetric flow rate the liposomes dimension decreases; at equal flow rates, when the lipids concentration increases also the liposomes size has been observed increasing. },
