Abstract
Green active film from chitosan (C) incorporated with spontaneous emulsified cinnamon oil nanoemulsion (CONE; droplet size of 79.27 nm and polydispersity index of 0.27) was developed. The obtained chitosan film containing CONE (C + CONE) had tensile elongation and light protective effect higher than C film due to the incorporation of bioactive compounds from cinnamon oil as proven by Fourier Transform Infrared Spectroscopy. The effect of C + CONE as active edible coating on the physical, chemical, and microbiological properties of dried shrimp was then investigated. The quality of samples coated with C + CONE (DS + C + CONE) was compared to those coated with C (DS + C) and without coating (DS). In this study, C + CONE could enhance astaxanthin content and reduce lipid oxidation in dried shrimp. During 6 weeks of storage, C + CONE was found to be an effective antimicrobial coating that significantly inhibited growth of bacteria, delayed lipid oxidation and retarded the production of volatile amines in dried shrimp. DS + C + CONE had lower malonaldehyde equivalents (0.52 mg/kg oil), trimethylamine (11.74 mg/100 g), total volatile base nitrogen (84.33 mg/100 g) and total viable count (4.80 Log CFU/g), but had higher astaxanthin content (12.53 ± 0.12 μg/g) than DS and DS + C. The results suggested that the developed C + CONE coating has potential to be used as active coating for preserving food quality.

Abstract
In this paper, an oil-in-water (O/W) nanoemulsion (NE) prepared by water cold dilution of an O/W microemulsion (ME) was introduced as a sample matrix in microemulsion electrokinetic capillary chromatography (MEEKC) for the highly hydrophobic compounds analysis. Several model compounds with log PO/W values in the 4.1-10.9 range, from different chemical groups, including retinol, α-tocopherol, cholecalciferol, phylloquinone, menaquinone-7, dichlorodiphenyltrichloroethane, ivermectin have been tested. As a proof of the concept of NE formation, a dynamic light scattering technique was employed to determine the size distribution profile of NE particles. Moreover, due to relatively low conductivity of the NE matrix (50-100 times lower in comparison to the separation buffer) and a negative electric charge provided to hydrophobic compounds through NE dispersed phase, NE matrices have been combined with preconcentration techniques based on electrokinetic dosing, namely field amplified sample injection (FASI) and pressure assisted electrokinetic injection (PAEKI). The detection limits for vitamin K1 and K2-MK7 in the NE matrix in combination with FASI (NE-MEEKC-FASI) as well as PAEKI (NE-MEEKC-PAEKI) were up to 42.9 and 12.1 ng mL-1, respectively. In comparison to standard hydrodynamic injection for microemulsion sample matrix NE-MEEKC-PAEKI grant 45-fold improvement in signal sensitivity. The study presents an innovative approach, as it enables the use of preconcentration techniques for highly hydrophobic compounds (log PO/W > 4), which was not previously possible for implementation in the electromigration techniques. Likewise, the use of organic solvents has been reduced by using ME as a solvent for stock solutions and diluting with water prior to the analysis. The application to real samples was investigated using a dietary supplement containing vitamin K2-MK7 obtained from the fermentation product of soybeans.

Abstract
The present research had been attempted to formulate and characterize tocotrienols-rich naringenin nanoemulgel for topical application in chronic wound conditions associated with diabetes. In due course, different phases of the nanoemulsion were chosen based on the solubility study, where combination of Capryol 90 and tocotrienols, Solutol HS15, and Transcutol P were selected as oil, surfactant, and cosurfactant, respectively. The nanoemulsions were formulated using the spontaneous emulsification method. Subsequently, Carbopols were incorporated to develop corresponding nanoemulgels of the optimized nanoemulsions. Thermodynamically stable optimized nanoemulgels were evaluated for their globule size, polydispersity index (PDI), surface charge, viscosity, mucoadhesive property, spreadability, in vitro release and release mechanism. Further, increasing polymer concentration in the nanoemulgels was reflected with the increased mucoadhesive property with corresponding decrease in the release rate of the drug. The optimized nanoemulgel (NG1) consisted of uniform dispersion (PDI, 0.452 ± 0.03) of the nanometric globules (145.58 ± 12.5) of the dispersed phase, and negative surface charge (−21.1 ± 3.32 mV) with viscosity 297,600 cP and good spreadability. In vitro release of naringenin in phosphate buffer saline revealed a sustained release profile up to a maximum of 74.62 ± 4.54% from the formulated nanoemulgel (NG1) within the time-frame of 24 h. Alternatively, the release from the nanoemulsion was much higher (89.17 ± 2.87%), which might be due to lack of polymer coating on the dispersed oil droplets. Moreover, the in vitro release kinetics from the nanoemulgel followed the first-order release and Higuchi model with non-Fickian diffusion. Therefore, encouraging results in this research is evident in bringing a promising future in wound management, particularly associated with diabetes complications. Thermodynamically stable naringenin-loaded tocotrienol-rich nanoemulgels were fabricated using spontaneous method. Developed nanoemulgel possesses nanometric globule size with good spreadability. Controlled in vitro release was obtained over a period of 24 h. First-order release and Higuchi model with non-Fickian diffusion was established in the in vitro release kinetic profile. This nanoemulgel could be a promising tool in the management of chronic wound condition.

Abstract
The phase and diffusion characteristics of ternary mixture (oil, surfactant, and co-surfactant) were investigated for their utilization as a precursor for the fabrication of lipid-based delivery carriers. Different types of phases (W/O microemulsion, bicontinuous, liquid crystal, gel and O/W conventional emulsion phases) were generated depending on the content of the co-surfactant aqueous solution. A suspension with the smallest lipid particle was obtained from the bicontinuous phase, followed by the W/O microemulsion, liquid crystal, O/W conventional emulsion, and gel. The W/O microemulsion and bicontinuous phases showing a phase transition into the hexagonal phase of lyotropic liquid crystal, were found to be suitable for lipid-based delivery carriers with small particle size distribution and quercetin encapsulation efficiency. Thus, the ternary mixtures of oil, surfactant and co-surfactant could be utilized as a precursor for the production of lipid-based delivery carriers with various particle sizes.

Abstract
Perfluorohexane-loaded nanocapsules are interesting materials for many biomedical applications such as oxygen delivery systems or contrast agents. However, their formulation into stable colloidal systems is challenging because of their hydro- and lipophobicity, high density and high vapour pressure. In this study, perfluorohexane-loaded polymeric nanocapsules are prepared for the first time by low-energy emulsification and selective solvent diffusion. The colloidal stability of the perfluorohexane nano-emulsion templates has been improved by the incorporation of an apolar low-density oil (isopropyl myristate) in the dispersed phase, thus addressing droplet coarsening and migration phenomena. The perfluorohexane-loaded nanocapsules prepared from the nano-emulsions show sizes smaller than the corresponding emulsion templates (below 150 nm by dynamic light scattering) and exhibit good stability under storage conditions. Hyperspectral enhanced dark field microscopy revealed a layered core/shell structure and allowed also to confirm the encapsulation of perfluorohexane which was quantified by elemental microanalysis. Although isopropyl myristate has an unfavourable biocompatibility profile, cell viability is enhanced when perfluorohexane is present in the nanocapsules, which is attributed to its high oxygen transport capacity.

Abstract
Encapsulation of magnetic nanoparticles (MNP) into PLGA nanoparticles has been achieved by nano-emulsion templating using for the first time both, a low-energy emulsification method as well as biocompatible components accepted for pharmaceuticals intended for human use. The incorporation of MNP by nano-emulsion templating method proposed in this work has been investigated in two different systems applying mild process conditions and is shown to be simple and versatile, providing stable MNP-loaded PLGA nanoparticles with tunable size and MNP concentration. MNP-loaded PLGA nanoparticles showed sizes below 200nm by DLS and 50nm by TEM, and mean MNP loading per PLGA nanoparticle of 1 to 4, depending on the nanoparticle dispersion composition. Physical-chemical features suggest that the MNP-loaded PLGA nanoparticles obtained are good candidates for intravenous or intratumoral administration.
