vitamin e (α-tocopherol) is a natural antioxidant very useful for preventing the harmful effects of uv sun rays as skin aging and cancers. in this study, different mlv formulations were made using egg lecithin and varying molar ratios of α-tocopherol and/or cholesterol, and their encapsulation efficiencies were determined. the best liposomal product was incorporated into a carbomer 980 gel. the...
Rifampicin biodegradable microcapsules were prepared by feasible emulsification-ionic gelation method for a novel controlled release product. Sodium alginate and Carbopol 974P were used as coating polymers in different ratios 1:1, 1:2, 1:3 and 1:4 to obtain elegant microcapsules. The formulations were characterized for encapsulation efficiency, drug loading, sieve analysis, scanning electron mi...
The aim of this study was to develop ethosomes loaded with cryptotanshinone (CPT) and formulate them as a topical gel for the treatment of acne. Ethosomes were prepared and evaluated for vesicle size, CPT loading and encapsulation efficiency. Optimized ethosomes were formulated as Carbomer 974 gels and compared with conventional hydroethanolic gels for transdermal permeation and skin deposition...
The purpose of this study was to prepare and characterize microspheres loaded by Aceclofenac. To achieve this goal Chitosan and Sodium alginate microspheres loaded by Aceclofenac were prepared by emulsification and ionic gelation methods. Morphology, size, encapsulation efficiency and drug release from these microspheres were evaluated. Microscopic evaluation of microspheres showed that microsp...
INTRODUCTION Single-cell isolation is important for biochemical screening platform in which each cell can be genetically varied and observation of individual reaction level is necessary. Microfluidic droplet-based technology enables the isolation of cells in individual aqueous chamber, but single-cell encapsulation efficiency is usually as low as 22% [1]. Several reports have been presented to ...
In this study, the preparation, characterization and drug release behaviour of gentamicin (GM)-loaded poly(D,L-lactide-co-glycolide) microspheres are described. The microspheres were produced using a double emulsion solvent evaporation technique. All the microspheres preparation resulted in spherical shape and the mean diameter was 3 microm (for empty microspheres) and between 5 and 9 microm fo...
The purpose of the present study was to prepare psoralen-doxorubicin nanostructured lipid carriers (PSO-DOX-NLC) with better physicochemical properties for further study on its multidrug resistance reversal activity on leukemia cells. PSO-DOX-NLC was synthesized by emulsion evaporation and solidification at a low temperature. PSO-DOX-NLC morphology and particle size were examined using transmis...
0.1016/j.nanoen.2 lsevier Ltd. All rig thor. [email protected] ( Abstract The efficiency of organometal trihalide perovskites (OTP) solar cells have reached that parity of single crystal silicon, and its nature abundant raw material and solution-process capability promise a bright future for commercialization. However, the vacuum based techniques for metal electrode deposition and additional encap...
