Production of hollow metal microcylinders from lipids

摘要

Process for making metallic microcylinders from pretreated diacetylenic lipid tubules which includes placing the tubules into an electroless plating bath containing a metal plating reagent, depositing by electroless plating on the surfaces of the tubules enough of a metal to make the tubules electrically conducting, separating the tubules from the plating bath, treating the tubules to remove the lipid and form the metal microcylinders, washing and drying the microcylinders to produce the metal microcylinders having aspect radio of about 12, weight average length of about 20 &mgr;, weight average outside diameter of about 1.5 &mgr;, and weight average wall thickness of about a quarter of one micron.
