22. Effects of temperature, acyl chain length, and flow-rate ratio on liposome formation and size in a microfluidic hydrodyanmic focusing device
Topic: Microfluidics
Published: 3/21/2010
Authors: Justin M Zook, Wyatt N Vreeland
Abstract: Microfluidic hydrodynamic focusing of an alcohol/lipid mixture into a narrow fluid stream by two oblique buffer streams provides a controlled and reproducible method of forming phospholipid bilayer vesicles (i.e., liposomes) with relatively monodispe ...

24. IMPACT OF IMMOBILIZATION SUPPORTS FOR POLYESTERS SYNTHESIS ACTIVITY OF CANDIDA ANTARTICA LIPASE B
Topic: Microfluidics
Published: 1/1/2010
Authors: Atul Bhangale, Santanu S. Kundu, Wenchun Xie, William E Wallace III, Kathleen M. Flynn, Kathryn L Beers, Richard Gross
Abstract: Epoxy functionalized supports are known to be suitable for industrial-scale immobilization of enzymes for biocatalysis. However, chemistry across these epoxy groups is known to affect the catalytic performance of the enzymes.In order to achieve a ba ...

27. Droplet Formation at Microfluidic T-junctions
Topic: Microfluidics
Published: 12/31/2008
Authors: David A LaVan, Xiang Xu
Abstract: Analysis of droplet formation in microfluidic systems is important to understand the operation of these devices, and to permit optimal design and process control. Droplet formation in microfluidic T-junction devices was studied using experimental an ...

Topic: Microfluidics
Published: 10/20/2008
Author: Andreas Jahn
Abstract: A method is presented for achieving high entrapment efficiencies of a hydrophilic drug simulant, sulforhodamine B (SRB), in nanometer-scale liposomes using a continuous-flow microfluidic system. Liposome size and size dispersion are determined using ...
