Abstract

Disclosed is an apparatus and method for inserting one or several chemical or biological species into phospholipid containers that are controlled within a microfluidic network, wherein individual containers are tracked and manipulated by electric fields and wherein the contained species may be chemically processed.

Claims (8)

1. A synthetic vesicle having a bilayer membrane comprising 1-Palmitoyl-2-10, 12 tricosadiynoyl-sn-glycero-3-phosphocholine and cholesterol in a 10:1 molar ratio.

2. A synthetic vesicle formed by the process, comprising the steps of:

preparing a carrier media solution comprising chloroform and methanol;

preparing a liposome solution of 0.1M 16:0-23:2 DIYNE PC dissolved in chloroform and a cholesterol solution of 0.1M cholesterol solution dissolved in chloroform, said 16:0-23:2 DIYNE PC having polymerizable tail groups;

combining said liposome, said cholesterol, and said carrier solutions together with a quantity of phosphate buffer saline solution (“PBS”) to provide a vesicle solution;

introducing said vesicle solution into a rotary evaporator;

applying a dynamic partial vacuum to said rotary evaporator in order to boil off said carrier solution and thereby leaving a polydisperse vesicle solution encapsulating PBS; and

irradiating said vesicle solution with a source of ultraviolet light in order to polymerize said tail groups.
