Process optimization for preparation of curcumin and quercetin co-encapsulated liposomes using microfluidic device
The aim of this study was to prepare, characterize and evaluate liposomes co-encapsulated with curcumin and quercetin using a droplet-based microfluidic device. Curcumin and quercetin co-encapsulated liposomes made of phosphatidylcholine and cholesterol were synthesized using a droplet-based microfluidic device with different flow rate ratios of 9:1, 6:1, 3:1 and 1:1 of the aqueous to organic phase at 100 to 160 µl/min flow rate. The dynamic light scattering technique showed that 9:1 and 6:1 flow rate ratios at 140 and 160 µl/min flow rates, respectively provide desired particle size range of 200–250 nm and 0.17–0.23 polydispersity index. The greatest encapsulation and loading efficiency achieved for curcumin and quercetin was 68 ± 9.2%, 14 ± 1.8%, and 36 ± 2.7%, 7.2 ± 0.5%, respectively with 6:1 flow rate ratio. Cell uptake studies performed on human oral carcinoma cells, FaDu using confocal laser scanning microscopy showed that the liposomes were taken up within 2 h. Clathrin and caveolin-mediated pathways contribute to the cell uptake of liposomes. The FaDu cell viability was reduced to 49 ± 2.2, 69 ± 1.5 and 47 ± 3.5% after incubation with liposomes containing curcumin (80 µM), quercetin (86 µM) and combination (32 µM of curcumin and 26 µM of quercetin), respectively. Apoptosis assay showed that the combination liposomes inhibit FaDu cell growth through apoptosis induced cell death. In conclusion, co-encapsulated liposomes can be prepared by microfluidics-based method and curcumin and quercetin combination liposomes are effective against oral carcinoma.
期刊介绍:
Microfluidics and Nanofluidics is an international peer-reviewed journal that aims to publish papers in all aspects of microfluidics, nanofluidics and lab-on-a-chip science and technology. The objectives of the journal are to (1) provide an overview of the current state of the research and development in microfluidics, nanofluidics and lab-on-a-chip devices, (2) improve the fundamental understanding of microfluidic and nanofluidic phenomena, and (3) discuss applications of microfluidics, nanofluidics and lab-on-a-chip devices. Topics covered in this journal include:
1.000 Fundamental principles of micro- and nanoscale phenomena like,
flow, mass transport and reactions
3.000 Theoretical models and numerical simulation with experimental and/or analytical proof
4.000 Novel measurement & characterization technologies
5.000 Devices (actuators and sensors)
6.000 New unit-operations for dedicated microfluidic platforms
7.000 Lab-on-a-Chip applications
8.000 Microfabrication technologies and materials
Please note, Microfluidics and Nanofluidics does not publish manuscripts studying pure microscale heat transfer since there are many journals that cover this field of research (Journal of Heat Transfer, Journal of Heat and Mass Transfer, Journal of Heat and Fluid Flow, etc.).
