ABSTRACT:
The wall thickness of lipid microtubules are controlled by selecting a methanol/water system and determining the required amount of a lipid to form the desired wall thickness. The lipid is dissolved in a small portion of the heated methanol and that clear solution is added to the remaining amount of the heated methanol/water system. By slowly cooling the solution, microtubules are formed which have the desired wall thickness. Preferred microtubules have a wall thickness of just 2 bilayers and they are robust so they can be further coated. They can be made with a large aspect ratio and with lengths of greater than 250 microns. The process permits production of microtubules in very high yields.
