Vesicle-based method for collecting, manipulating, and chemically processing trace macromolecular species
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.
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.
